Fourteen years It's a little hard to believe. Fourteen years ago today, I launched Buffer from my apartment in Birmingham, in the UK. The launch came seven weeks after I started working on the project on the side as a contract web developer. For a few weeks, I called it bfffr until I realized that no one knew how to pronounce it. Sometimes it's better to be clear than clever. So it became bufferapp.com. Even then, people thought we were called Buffer App for a while! Eventually we were able to acquire buffer.com and clear up the confusion altogether. When I started Buffer, I had no idea how far it could come. This was a case where the dream formed over time, rather than being fully formed on day one. There's a dogma that you need to have complete clarity of the vision and outcome before you even start (and go all-in and full-time, which I also disagree with). I think there's a beauty in starting with a small dream. It just so happens that every big thing started small. Early on, my dream was just to create a tool that made it easy to Tweet consistently, build it for myself and others, and make enough money to cover my living expenses and go full-time on it. The number for me to be able to work on it full-time was £1,200 per month, and that felt almost out of reach in the beginning. Today, Buffer generates $1.65 million per month, serves 59,000 customers, and enables fulfilling work for 72 people. I've had many dreams with Buffer, each one progressively becoming more ambitious. To me it's always felt like I can just about see the horizon, and once I get there, I see a new horizon to strive for. I've tried to embrace that Buffer can continue to evolve as I, the team, and customers do. A lot happens as a founder and as a business in fourteen years. I started the company when I was 23. I was young, ambitious, and had so much to learn. My naivety served me well in so many ways. At the same time, I like to think that the years have given me a more intentional, decisive approach to business. Broadly, it feels like we've had three eras to the company so far. In our first era, we found traction, we built swiftly and with fervor, we grew a special community of users and customers, and we did it all in our own way. We were a remote company before almost anyone else, and were part of the earliest days of building in public. There's so much we did right in that first era, though we also had wind in our sails which masked our errors and immaturity. The second era of Buffer was marked by growing pains, a struggle to understand who we really are, missteps and through that, transformation, clarity, and new beginnings. These years were very much the messy middle of Buffer. They were also where I experienced my lowest lows in the journey so far. As hard as this experience was, I am grateful as it was the path I needed to walk in order to grow as a leader, cement our independence and long-term ambitions, rediscover Buffer's purpose, and start to operate with greater conviction. We're a couple of chapters into our current era. With a renewed focus on entrepreneurs, creators, and small businesses, we started making bolder moves to serve them and create a more unique offering in what had become a very crowded and commoditized space. Through a clearer strategy, strengthening our culture, and improving how we work as a team, we emerged from a multi-year decline. Last year, we turned the ship around and had a flat year. This year, we're on track for over 10% growth and a profitable year. It doesn't feel like a coincidence to me that this final era has also been the phase where I've experienced one of the most joyful and demanding experiences as a human: becoming a parent. I have a wife and I have two young boys, and they mean the world to me. I also started prioritizing my community of family and friends, as well as cultivating hobbies again. I spend time on my health and fitness, try to keep up my skiing, and recently picked up playing the piano again. Time has become a lot more precious, and with that, clarity and conviction are more vital than ever. As much as it sometimes feels hard to fit everything in, to me, it's the whole package that makes life fulfilling. When I really stop to take a step back, I feel very lucky that I've been able to do this for fourteen years. It's a long time in any sense. In tech and social media it feels like almost a lifetime already. And yet, just like those early days when I could barely imagine reaching £1,200 per month, I'm still looking toward that next horizon. I see a clear opportunity to help entrepreneurs, creators and small businesses get off the ground, grow, and thrive long-term. Photo by Simon Berger on Unsplash.
The significance of Bluesky and decentralized social media I'm delighted to share that we have introduced support for Bluesky in Buffer. This is an important moment for us as a company, and there are a number of reasons that adding Bluesky is personally meaningful for me. With Bluesky, we now support the three major social networks pushing forward a new era of decentralized social media: Mastodon, Threads and Bluesky. We have been intentional about moving fast to add these channels to our tool. Supporting independence and ownership in social media Buffer has now existed for almost 14 years, and throughout that time I've seen a lot change in social media, and in our space of tools to support people and businesses with social. We're an outlier as a product and company that has existed for that kind of timeframe with leadership and values left in tact. We've had to work hard at times to maintain control over our destiny. In 2018, we made the decision to spend $3.3M to buy out the majority of our VC investors and be able to go our long-term path. We have continued to carry out buybacks each year since 2018, and at this stage we are majority founder and team owned. One of the things I'm proudest of is that we still wholeheartedly serve individuals and creators, and have not gone up-market as many other long-running companies in our space have done. We've been fortunate to be able to scale to 56,000 paying customers and over $18M in annual revenue while taking our own unique path. Through intentional choices over the years, we have maintained a level of optionality over our future that most do not have. This independence is something I don't take for granted. Keeping ownership of our company, and through that ownership having an ability to boldly go in the direction we believe is best for customers and the team, is very important to me. This is why, as a business, we feel so philosophically aligned with rising new decentralized social media networks, such as Bluesky and Mastodon. These networks have been started with a belief that individuals should maintain ownership over their content and the connection to their audience. They have data portability baked in from the beginning. When you use these networks, you are much more likely to be able to maintain control over your content and audience than if you use social networks owned by large corporations with complex ownership structures of their own, and often with public markets to answer to. The larger social networks provide a level of distribution that's worth tapping into, but I strongly encourage investing a portion of your energy into networks where you will be able to maintain ownership long-term. At Buffer, we will be doing everything we can to support the growth of new decentralized social media options, because we believe that individuals and small businesses should maintain control over their content and the connection to their audience. The resurgence of the open web with social media protocols I have been eagerly observing the emergence and growth of social media protocols, in particular with ActivityPub (and Mastodon as the prominent implementation), and AT Protocol from Bluesky. Open standards in social media could be as powerful as open standards have been for direct and private communication (email). What I find exciting about the development of these open standards, and more importantly the adoption of them and traction of social networks which support them, is that they can bring forth a new era of open standards for the web. The Internet was built upon open standards — HTTP, URL, TCP/IP, DNS, HTML. A vast many valuable internet businesses have built on these "shoulders of giants." ActivityPub and AT Protocol are built with open standards philosophies, and could similarly enable a new playground of innovation, with openness, ownership and interoperability at their core. I personally miss the earlier days of social media where the APIs had much greater parity with what could be done natively on the platforms. When I started Buffer, the Twitter and Facebook APIs were close to feature-complete, and brought about a lot of innovation in third-party development on top of those APIs. This is how Buffer was born, along with many other products in our space. Over time, we saw an era of closed APIs with reduced transparency and ownership of content and audiences. Mastodon and Bluesky bring the opportunity for a new era of innovation in our space, which I am welcoming with open arms. More innovation in the social media management space will be better for customers, and frankly makes for more exciting work to do. Bluesky is bringing innovation back to social media If you haven't had a chance to take a look at some of Bluesky's recent product and platform announcements, I highly recommend that you go and read them. In particular, what they've done with introducing custom feeds as well as starter packs gets me very excited about some real innovation from a social network. When I saw starter packs introduced, it immediately felt like a no-brainer feature for a social network, and such a powerful thing, especially for an emerging social network, to offer. Starter packs allow anyone to create a "getting started pack" for a new Bluesky user. This can include a set of recommended follows, and up to three recommended custom feeds (more on those below). This enables their passionate users to be able to personalize an introduction for people not yet on Bluesky. It's a smart way to activate users to play a meaningful role in onboarding new people to the network and grounding them with an existing community to interact with. Of course, Bluesky benefits by likely getting more people onto their new network than they would otherwise. Custom feeds are an incredible innovation that put the choice of algorithm for the social network in the hands of the wide range of users and different niche communities that exist on the network. The way that the Bluesky team have built custom feeds enables a ton of flexibility for the types of content alogrithms can serve up, and creates a marketplace for browsing and enabling different custom feeds you can choose to view. Something I've observed from the Bluesky team is their commitment to, and intentionality around, building tools for the governance of the network itself. It's very meaningful that on Bluesky you can choose your own algorithm and you can adopt an algorithm that someone else has written, or create your own algorithm for what content shows up in your feed. And I think it's very smart that Bluesky has done this — because it's both innovation and it's strong strategy because it's a highly defensible move which many of the other networks would not be able offer. It would be very unlikely for the commercial social networks to move away from the company, the network themselves, holding on to ownership of the algorithm and what is served up to you. I had a wonderful conversation with Rose Wang from the Bluesky team a couple of weeks ago and one of the topics we got into was around the values that are embedded in the Bluesky team and the work they're trying to do. It was clear to me how thoughtful and intentional they are being around the governance of the network and the flexibility they're building in to allow users to really shape the community and what is important to them. Something I appreciate about Bluesky is that their goal is to create a social network not controlled by a single company, while also ensuring that it comes together as a cohesive and easy-to-use experience. Decentralized social media can be daunting and feel complex and inaccessible to people initially, and so I think intentional work going into the simplicity of the experience is paramount. With great innovation from the Bluesky team such as starter packs and custom feeds, along with their focus on simplicity, I strongly encourage you to go and take a look at this new social network. This is a platform and community that's worth taking a deeper look at, participating in and investing time into. Join us in participating in a new era of decentralized social media By supporting Bluesky, along with Mastodon and Threads, we are playing our part in moving forward this promising new era of social media. Many of us in the team have been personally drawn to these networks for their special and supportive communities. We're here to see decentralized social media grow and become more meaningful for more people across the world. That's why we've put our scale, brand and resources into building awareness and providing tools to make participating on these new social networks more streamlined. I encourage you to add Bluesky to your channels in Buffer, and start participating in the social network today. Learn more and get started by visiting our Bluesky page.

Our vision for location-independent salaries at Buffer Note: this was originally posted on the Buffer blog. I’m happy to share that we’ve established a long-term goal that salaries at Buffer will not be based on location. We made our first step towards this last year, when we moved from four cost-of-living based location bands for salaries to two bands. We did this by eliminating the lower two location bands The change we made resulted in salary increases for 55 of 85 team members, with the increase being on average $10,265. When the time is right, we will be eliminating the concept of cost-of-living based location bands entirely, which will lead to a simpler approach to providing generous, fair and transparent salaries at Buffer. In this post I’m sharing my thinking behind this change and our approach to pay overall. Location and Salaries It’s been interesting to see the conversation about location and salaries unfold both within Buffer and beyond. We’ve heard from many teammates over the years about the pros and cons of the location factor, and of course we’ve watched with interest as this became a regular topic of conversation within the larger remote work community. I've had many healthy debates with other remote leaders, and there are arguments for eliminating a location component which I haven’t agreed with. I don’t believe pay differences across locations is unethical, and it has made a lot of sense for us in the past. However, the last few years have seen a lot of change for remote teams. A change like this isn't to be made lightly, and at our scale comes with considerations. Our Compensation Philosophy Compensation is always slowly evolving as companies and markets mature and change. We’ve been through several major iterations of our salary formula, and myriad small tweaks throughout the last 8 or so years since we launched the initial version. Part of the fun of having a salary formula is knowing that it’s never going to be “done.” Knowing that the iterations would continue, Caryn, our VP of Finance, and I worked together to establish our compensation philosophy and document our principles on compensation to help us determine what should always be true even as the salary formula changes over time. We arrived at four principles that guide our decisions around compensation. We strive for Buffer’s approach to salary, equity, and benefits to be: Transparent Simple Fair Generous These are the tenets that have guided us through compensation decisions over the years. After we articulated them as our compensation principles, we were able to look at the location factor of our formula with new clarity. There are a few key considerations that were part of our discussions and my decision to put Buffer on a path towards removing our location factor from salaries that I'll go into more detail about next. Transparency, Simplicity, and Trust Our salary formula is one of the fundamental reasons that we can share our salaries transparently. Having a spreadsheet of team salaries is a huge step toward transparency, but true transparency is reached when the formula is simple, straightforward, easy to understand, and importantly, easy to use. In one of our earlier versions of the salary formula, we calculated the cost-of-living multiplier for every new location when we made an offer. That was cumbersome, and it meant that a candidate couldn’t truly know their salary range until we calculated that. This was improved greatly when we moved to the concept of “cost-of-living bands.”. After that, different cities and towns could more easily be classified into each band. This massively increased the transparency of the formula, and I think it helped create a lot more trust in this system. Anyone could relatively easily understand which band their location fit into, and with that knowledge understand the exact salary they'd receive at Buffer. This type of immediate understanding of the salary formula, and ability to run calculations yourself, is where transparency really gains an extra level of impact and drives trust within and beyond the team. However, with our four cost-of-living bands, there were still decisions to be made around where locations fall, and this has been the topic of much healthy and productive debate over the years. The conversations around locations falling between the Average and High bands is what led us to introduce the Intermediate band. And with four choices of location, it has meant there is some disparity in salaries across the team. With the benefits that come from the powerful combination of transparency and simplicity, alongside the increased trust that is fostered with more parity across the team, I’m choosing to drive Buffer’s salary formula in the direction of eventually having no cost-of-living factor. Freedom and Flexibility We’ve long taken approaches to work which have been grounded in the ideal of an increased level of freedom and flexibility as a team member. When I started Buffer, I wanted greater freedom and a better quality of life than I felt would be possible by working at a company. That came in various forms, including location freedom, flexibility of working hours, and financial freedom. And as we’ve built the company, I’ve been proud that we’ve built a culture where every single team member can experience an unusual and refreshing level of freedom and flexibility. Since the earliest days, one of our most fondly held values has been to Improve Consistently, and in particular this line: “We choose to be where we are the happiest and most productive”. This is a value that has supported and encouraged teammates to travel and try living in different cities, in search of that “happiest and most productive” place. It has enabled people to find work they love and great co-workers, from a hometown near family where it would be hard to find a local company that can offer that same experience and challenge. It has also enabled people to travel in order to support their partner in an important career change involving a move, something which allows an often stressful change to happen much more smoothly, since you can keep working at Buffer from anywhere in the world. Having a culture that has supported moving freely across the globe has been a powerful level of freedom and flexibility. That freedom has been matched with a salary system which adjusts compensation to accommodate those changes in a fair and appropriate way. However, knowing that your salary will fluctuate and can decrease due to a choice to be somewhere else, does limit that freedom and the ability to make a decision to move. Moving towards a salary formula with parity across all locations, will enable an even greater level of freedom and flexibility. It feels clear to me that choosing to move is a personal or a family decision, and it is ideal if Buffer salaries are structured in a way that honor and support that reality. I’m excited that working towards removing our cost-of-living differences will help significantly reduce the friction involved in making a potentially positively life-changing decision to live in a different city or country. Results, Independence, and Reward At Buffer, we are not on the typical hyper-growth VC path. This comes with some constraints: we don’t have tens of millions in funding and unlimited capital to deploy in an attempt to find a rapid path to $100m and going public (thankfully, that’s not our goal). This path also means that our experiences as teammates in a variety of ways are directly tied to whether we are successfully serving existing and new customers. For example, the level of benefits, ability to travel (in normal times), and competitiveness of compensation, are very much driven by our revenue growth and profitability. But, this is independence too. The thing we often need to remind ourselves of, is that while we may feel more constrained at times, we have full freedom of what we do with the success we achieve. Making a choice like this is one example of that. It is my intention as founder / CEO that as we succeed together as a company, we all benefit from that success and see adjustments that improve our quality of life and create wealth. We are in a position of profitability which allows us to take a significant step towards removing the cost-of-living factor from our salary framework, which I believe serves those goals. And removing it entirely will be determined by us successfully executing on our strategy and serving customers well. Reducing Cost-of-Living Bands The way our salary formula works is that we benchmark a teammate’s role based on market data at the 50th percentile for the software industry in San Francisco and then multiply that by the cost-of-living band. So, a Product Marketer benchmark at the 50th percentile of the San Francisco market data is $108,838. Depending on the teammate’s location this would be multiplied by a cost-of-living band (Low, Average, Intermediate or High). For example, if they lived Boulder, Colorado, a city with Average cost-of-living, the benchmark would be multiplied by 0.85 for a salary of $92,512. To best reflect our compensation philosophy, company values, and the path we want for Buffer, we have eliminated the Low and Average cost-of-living bands. What we’ve done is brought all Low (.75 multiplier) and Average (.85 multiplier) salaries up to Intermediate (.9 multiplier), which we now call our Global band. This is what resulted in 55 teammates seeing on average an increase to their salary of $10,265. Our two bands are now Global (.9 multiplier) and High (1.0 multiplier). This change is based on my vision for Buffer and how being a part of this team affects each of us as individually, as well as the direction I believe the world is going. I’m excited about the change first and foremost because it supports our goal of having a transparent, simple, fair, and generous approach to compensation. This is also a move that raised salaries right away for more than half of the team. This point in particular gives me a lot of joy because I want compensation to be one of the incredible parts of working at Buffer. Money isn’t everything, and we all need kind and smart colleagues, a psychologically safe environment, and to work on challenging and interesting problems, in order to be fulfilled at work. Beyond that, however, money really impacts life choices, and that’s ultimately what I want for every Bufferoo; the freedom to choose their own lifestyle and make choices for themselves and their families’ long-term health and happiness. It’s important to me that people who choose to spend their years at Buffer will have the freedom to make their own choices to have a great life. And, for our teammates who live in much lower cost-of-living areas, a Buffer salary could end up being truly life changing. I’m really happy with that outcome. The decision was also impacted by the direction that I believe the world is going (and, the direction we want to help it go). Remote is in full swing, and it’s increasingly breaking down geographical borders. I believe this is a great thing. Looking ahead 10 or even 5 years, it seems to me that we’re going to see a big rebalancing, or correction, that’s going to happen. I believe it’s important to be ahead of these types of shifts, and be proactively choosing the path that’s appropriate and energizing for us. What next? Our plan is to eventually get to one single location band, essentially eliminating the cost-of-living factor from the salary formula altogether. This will be possible once we can afford to make this change and sustain our commitment to profitability. So, this will be driven by the long-term results we create from our hard work, creativity in the market, and commitment to customers. What questions does this spark for you?

Details of how the White House tried to suppress the vote by messing with mail-in voting. An early proposal was that all ballots would have to be sent via certified mail.
Today we are releasing the version 1.0 of Lexxy. Lexxy is a rich text editor for Rails built on Lexical. It already powers Basecamp, Fizzy and many others, and it will become the default editor in Rails. I recently presented it in Rails World (slides, video coming soon). This is the article version of my talk. Trix hit a wall Trix has been our editor since 2015, and every Rails app’s editor since Action Text shipped in Rails 6. It’s small and reliable, and it has served millions of people for a decade. But in the last few years our customers kept asking for features like tables or code highlighting, and we kept struggling to deliver them. The reason is the Trix document model. A Trix document is a flat list of blocks. A block is a line of text with some labels attached, like quote, bullet list, bullet. There is no tree, and a block can never contain another block. Nesting is an illusion: at render time, adjacent blocks with the same labels get wrapped together. A flat list of blocks with very limited extensibility options That design bought a lot of simplicity, but you can’t express something like a table with it. Two cells next to each other would carry exactly the same labels, so Trix would merge them into one. The model can say “this bullet is one level deeper”. It cannot say “this cell is different from the cell next to it”. A tables issue has been opened since 2015! The model just can’t do it. The second problem was maintenance. An editor built on contenteditable behaves differently in every browser and even changes from time with operating system releases. In 2024, three iOS releases in a row broke typing, dictation or the caret in Trix, and each one cost us real effort to work around. Check this one as an example. Why Lexical This was a conversation we had at 37signals for years: 2022. We started a project to add tables to Trix. We gave up after a week. The document model can’t represent two-dimensional things. 2023. I built a proof of concept with Tiptap inside HEY. We liked it, but we never started a serious project with it. 2024. We built House, our own Markdown editor, for Writebook. Not WYSIWYG, but WYSIWYM: what you see is what you mean. A wonderful editor for long-form writing like books or technical documentation. 2025. We tried House in another product, and it didn’t fit. For most apps, WYSIWYG was just the right answer. 2025. We had the discussion again, and this time we looked at the whole field. Four years of the same conversation David ruled out Tiptap, CKEditor and the other commercial editors: an open source core with features kept proprietary, and a sales team behind them. We didn’t want our editor to depend on somebody else’s licensing decisions. Then we found Lexical: MIT, from Meta, and very powerful. I spent two weeks evaluating it, and in May we made the call to go with it. A tiny core. Pick the rest. Lexical’s core has zero dependencies and weighs forty-two kilobytes. In a way, it validates the approach that Trix pioneered. The document is an immutable state you never mutate directly, you just get new snapshots when performing updates; contenteditable is an input device and a rendering surface, never the source of truth. It has a DOM reconciler to update the actual DOM very efficiently, and other primitives to deal with handling commands and node transformations. Everything else, from lists to tables to markdown, is a package in the orbit. Lexxy uses thirteen of them. Lexical solved the maintenance problem too. Meta’s products like Facebook or Instagram use Lexical and their user count is in the hundreds of millions. This means that even small issues with new keyboards and devices are fixed fast by the dedicated Meta team that maintains it. Furthermore, Meta’s business is the products, not the editor. We much rather liked this structure of incentives for the long-term investment an editor represents. The iceberg The plan was simple. Pick Lexical, wire it up to Action Text, add a toolbar and ship it. Well, it didn’t go exactly like that. What you envision, and what's under the water Lexxy today is thirteen thousand lines of vanilla JavaScript on top of Lexical. A great editing experience is very hard to get right. An editor is a machine where the user can change the state in a thousand different ways. For example. you have two images one after the other and want to put the cursor between them, but there is nothing there to put a cursor in. Or somebody pastes from Google Docs, and you have to turn a pile of inline styles and empty spans into clean markup. And then Safari, and Android keyboards, and the clipboard, and undo, and… From the first pull request to Basecamp 5 The first pull request landed in May 2025. Fizzy launched with Lexxy in December, and Basecamp 5 in May this year. Basecamp was the real test: twenty years of content written with Trix, and people who use the editor all day, every day. Zoltán Hosszú and Samuel Péchèr were the key people who made this happen. The took a very green version of Lexxy, added a ton of features (including Tables) and polish, and they fixed countless bugs. They also pulled off a remarkable milestone: seamlessly switching millions of Basecamp users from Trix to Lexxy. What’s included? We didn’t want a to build Trix with tables. We had Lexical and we had agents to help, so we wanted to be ambitious here. We went for the whole package. Features In terms of major features: A color highlighter, built in instead of this being a custom Basecamp extension, as it was with Trix. Tables, with an interface we worked hard to keep simple and accessible. Markdown. You type it, you get rich text. Code blocks with syntax highlighting as you type, in more than twenty languages. Image galleries you can navigate and reorder with the keyboard. Prompts. Type a character, get a menu: mentions, emoji, or whatever your app needs. Links by pasting a URL over selected text. Previews of attachments like videos and PDFs, rendered as your app renders them. Action Text Native Lexxy is also Action Text native. Action Text stores attachments in a canonical format that Trix doesn’t speak, so it translates on save and again on render. We taught Lexxy to emit exactly that markup. What you see in the editor is what gets saved, and what gets saved is what your app renders. Your existing content, attachments and views keep working. That opened another door. Action Text now talks to an editor adapter, with an implementation for Trix and one for Lexxy, so switching is one line: config.action_text.editor = :lexxy. Here the credit goes to Sean Doyle, who started that pull request before Lexxy existed and took it to the finish line with our input. It ships with Rails 8.2, and we hope other editors will use it too. Extensibility And you can extend Lexxy. Extensions are built on Lexical’s own mechanism, and this is not a second-class API: Lexxy itself is thirteen extensions, tables included, and Basecamp has nine more. class MyExtension extends Lexxy.Extension { get enabled() { … } get allowedElements() { … } get lexicalExtension() { return this.defineExtension({ name: "my-extension", nodes: [ … ], register(editor) { … } }) } initializeToolbar(toolbar) { … } dispose() { … } } Lexxy.configure({ global: { extensions: [ MyExtension ] } }) My favorite of how extensible is Lexxy are voice notes in Basecamp: you record, you see the waveform while you talk, and it becomes a player inside the document. About a thousand lines, without forking or patching anything. Performance Lexxy is fast, because Lexical is fast. In a ten thousand word document, Trix takes thirty-eight milliseconds to process a keystroke. Lexxy takes four. Above fifty milliseconds, the editor starts feeling sluggish. Compared to Trix, Lexxy brought a whole new performance regime. Milliseconds per keystroke by document size Accessibility Accessibility in Trix was not great. In general, building accessible experiences for rich text editors built on top of contenteditable is quite hard. We had a dream team to help with Lexxy accessibility. Bruno Prieto worked with Michael Berger, our accessibility champion at 37signals, to bring the bar to where we wanted it to be. Bruno is an outstanding programmer who happens to be blind, so he knows one thing or two about accessibility, and he delivered. As a result, in Lexxy everything is reachable with the keyboard. The editor announces itself properly to screen readers, and it gets a thousand details right so that the editing experience using a screen reader is fantastic. You can learn more about accessibility in our docs. Security The latest AI models have resulted in an unprecedented explosion of vulnerabilities found, and we took this thread quite seriously. Lexxy counted with programmers of the caliber of Jeremy Daer and Mike Dalessio helping to make it more secure. We have put a lot of attention to sanitizing the editor contents, validating attachment URLs and making sure that the types of attachments and nodes the editor support are allow-listed. Lexxy also comes with preliminary Trusted Types support, to offer CSP-level control over certain DOM manipulation APIs. The trusted types policy is there, but we are not enforcing it everywhere yet. Agents We started Lexxy using Claude since day one. A main lesson was that an agent needs to drive the editor like a user does. The best decision we made in this project was moving the system tests from Capybara to Playwright: three browsers instead of one, a suite that runs in seconds, and a much more faithful clipboard, keyboard and focus. This represented a tremendous improvement in how agents could close the loop by themselves. Write a test, see it fail, fix it, see it pass. We have more than six hundred browser tests today. Moving the suite to Playwright changed how fast we could write tests With a solid testing foundation in place, we could start fixing bugs in large batches. As mentioned, getting a text editor right implies a ton of work, and the kind of backlog we got at some point would have have buried us in pre-agent times. We also used agents to validate the fixes: an agent reproduces the bug in the public Lexxy sandbox, checks that it’s gone with the branch applied, and labels the pull request. Agents were essential to get Lexxy done with the people and the deadlines we had: we are a small company, and the same people were shipping two products in parallel. 275 cards closed The new Rails default We believe Lexxy is the best rich text editor out there right now, and we are going to make it the default editor in Rails next. If you’re starting a Rails application today, use Lexxy. If you’re using Action Text with a standard configuration, switch. It’s one line, and we’ve worked hard to make it seamless.
Reading my recent computing retrospective, I realised there was a big section missing: the people in my life that made an impact and helped shape my career. Outside my immediate family, one person made an outsized contribution, and I’m fairly certain that without his influence my life would have taken a very different path. The fact that I’m still here in 2026, still writing code and being fortunate enough to have a career in something I love is testament to him. So I’d like to take a few moments to talk about my old secondary school teacher, George Dryden. Denied Back in 1995, I had a problem. I knew I wanted to study computing at university and build a career out of my passion, but there was a snag. For those unfamiliar with the UK schooling system, when you’re 15-16 you take a set of GCSE exams in a broad range of subjects. After that, you pick around 3 subjects to really focus on over a period of 2 years. These are called A Levels, and they are a big step up and are meant to prepare you for a degree-level course at university. Admission to university is also governed by these results - if you want to study computing, you’re going to need a computing A-Level, and most universities will only accept you (or “make an offer”) if you achieve a certain grade. And whilst I had taken computing at a GCSE level, my school did not offer a computing A-Level course. I instead had to settle on “Design & Technology”, which just didn’t inspire me. Instead of working on my portfolio and projects, I spent most of my time daydreaming and writing code on the Acorn Archimedes computers that were the staple of every 90s UK school. No disrespect to the teachers - they were all awesome - but it just wasn’t for me. I was miserable, and by the end of my first year, I was well on my way to failing outright with my entire future plans seemingly going up in smoke. Someone noticed That’s when George stepped in. He’d taught me computing right the way through my GCSEs, and with no A-Level course on offer, that was officially where his involvement was supposed to have ended. It didn’t. He had noticed my constant presence in the computing labs - before and after school, during lunch breaks, free “study” periods - working on some little pet project or digging into RISC OS internals. I remember him as warm, with a wicked, dry sense of humour, and a refreshingly spiky attitude to authority - I always got the sense he’d worked out for himself which rules were worth taking seriously and which ones weren’t. And he always had time for me. I spent years pestering him with questions that had nothing to do with anything on the syllabus, and he’d always find a way to answer them that actually made sense. He was just as supportive of my odd little obsessions. At one point I’d got deep into the BBS scene, which I thought was the coolest thing ever, and decided what the school really needed was an internal BBS running on its own network. So I wrote one. It was deeply cringeworthy, obviously - but George helped me put posters up around the school advertising it, and even gave it a mention in assembly one morning. I think about five people in total ever checked it out. It didn’t matter: a teacher had stood up in front of the entire school and treated my weird little project like it was worth something, and that was a hugely validating moment for me. Off the books He recognised the passion, and eventually he made a suggestion: What if I quit the Design and Technology course, and instead attempt the A-level course myself? Personally, I also suspect he was enjoying himself. There was some internal school politics behind why computing wasn’t offered at A-Level in the first place - I never knew the details - and I think the prospect of one of his students simply going out and getting the qualification anyway appealed to him on two separate levels. It would get me where I wanted to go, and it would wind up exactly the right people. It wouldn’t be easy, he warned. The school would be against it, plus it was a two-year course which I’d have to cram into one year. I’d have to do it all myself - studying, lesson planning, coursework - he couldn’t help me in an official capacity, but he said he’d advocate for me and help where he could. If I had assignments, he’d send them off to be graded and would give feedback in his own time. He’d enter me in for the exams and also gave me a set of keys to the computer lab so I could use it whenever I needed. It was the first time anybody outside my own family had really shown faith in my abilities and encouraged me to take a stand. It was a pivotal moment for me - I realised if I wanted something badly enough I would have to fight for it, but I could still make it happen. I didn’t have to take “NO” for an answer - a lesson I think I picked up from watching him as much as from anything he ever actually said to me. After a few weeks of dithering, I took the jump. I remember a few awkward meetings with the school administration but thanks to his behind-the-scenes work, I was soon following my dream. An intense year And yes, it was bloody hard work. I had to condense an entire two year course into under a year, be disciplined enough to produce my own study plan, and be critical enough of my own shortcomings that I could focus my study where it was needed. I pretty much lived and breathed it for months straight and was more-or-less a permanent fixture in the labs or school library poring over my course books. I’d make lists of questions and chat to George over lunch, and he’d provide guidance and encouragement. It was a lonely way to learn with no classmates to compare notes with, no lessons to turn up to, and right up until the end I had no real idea whether any of it was good enough - but bit by bit, it started to feel like something I could actually pull off. And sure enough, in the late spring of 1996, I sat down in an exam hall with my fellow students, the only one with an A-Level computing question paper in front of me. The final exam went by in a blur - I can only remember a few of the questions now (and a peculiar obsession with the Pascal language) - but I do remember the euphoria as the invigilator called “time’s up, pens down, close your papers NOW”. I had done it. A few nerve-wracking months later, my Mum drove me into school to pick up my results. I ripped open the envelope and saw it - I’d passed with an A grade! I literally ran up the stairs to George’s office next to the computing labs to thank him personally. I’d taken my camera into school to take a few last photos for memory’s sake and snapped this photo of him before I walked out the school gates for the last time: A different path Because of him, I managed to get into my university of choice, studying computing with a focus on networks. Because of that, I landed my first job working as a “webmaster”, and my career since has been one of the highlights of my life. All these years later, it’s a real privilege to be able to get up each morning and actively look forward to working in an industry I love. Without George stepping up for me and encouraging me to believe in myself, none of that would have happened. I wouldn’t have had the career I have, and I wouldn’t be where I am now. I met my wife when we both worked at a software company - she sat at the desk behind me - so even my home and family life can be traced back to that spring of 1996. And the A-Level itself was only half of what I took away from that year. The qualification opened the door to university, but the lesson that came with it was every bit as important: that a “no” isn’t always the end of it, and that sometimes the answer can be argued with. I’m so proud of what I managed to achieve all those years ago, and even more thankful to have had someone like George in my life to put me on the right track. Mr. Dryden I did see him again after I left. He drank in one of my local pubs - a pub I’d been going to for a good while before I was technically old enough to be in it - and I’d say hello if I spotted him in there, mostly in the months before I moved away to university. After that it was only a handful of times. For years I’d find myself scanning the room whenever I was back home and in for a pint, half expecting him to be at the bar. At some point I stopped seeing him altogether and eventually moved across the country. The trouble was I never really knew how to talk to him outside of school. He was always Mr. Dryden, or just “Sir”, I don’t think I ever once called him George to his face! I was (and still am if I’m honest) fairly socially awkward, and I never worked out how to phrase the thing I actually wanted to say: that he had changed the entire direction of my life, and I wasn’t sure he knew it. So instead I’d say hello, and ask how he was, talk about nothing much, and go back to my friends. Epilogue Sadly, 3 years ago now, I opened the latest issue of my old school alumni newsletter to read that he’d passed away. The photo at the start of this article was taken from his obituary article and I read that he’d had a long illness and had suffered from dementia at the end. I did write to him years ago by email - I don’t know if he ever got it, or was in any capacity to understand what he’d done for me, but I hope so. There’s an old saying by one of my favourite authors (Terry Pratchett) that “no one is finally dead until the ripples they cause in the world die away”. In one of his books, a character keeps the memory of his son alive by passing his name along a series of telegraph towers. It’s in that spirit that I’m writing this post - I debated it for many years as it’s very personal to me and I also have no contact with any of George’s family so I have no idea what they would make of it all. But even though it’s 30+ years ago now, I will never forget him or what he did for me - and at least now, if someone searches his name it’ll be recorded here for as long as I’m alive and running this site. Thank you, Sir. George Dryden 1942-2023
