We just released @thoughtbot/react-native-social-auth; a modern Google Sign-In library for React Native built on top of Android’s Credential Manager and the current GoogleSignIn-iOS SDK. It ships with a Google-branding-compliant button component, a first-party Expo config plugin, and a TypeScript-fi...

One of the perks of being in the thoughtbot universe is that we meet a ton of people building cool things, and many of them are startup founders, mentors or advisors. Lately, we’ve chatted with them about how they’re using AI tools for startups, both where AI adds value and where they’re seeing risk...

IT and software leaders at healthcare organizations are feeling the pressure to deliver software faster while maintaining compliance and reliability. Our recent healthcare software delivery research (coming soon!) found that 68% of organizations struggle to increase software delivery velocity withou...

For more than a decade, Upcase was where thoughtbot taught Ruby on Rails. You’d work through a trail, get stuck, watch one of us solve the same problem, and come out a little sharper. Thousands of developers used it to take “junior” out of their title. We don’t say that lightly. In 2018, we transiti...

This week’s episode is a radical one, let’s Muppet-cast a software development team!

I have been working on an app that still sits on React Native 0.77 and the old architecture. Slowly, as I was getting a grip on the new architecture, one of the first big refactors was related to the navigation. We were using JavaScript stack navigators, so the plan was to move everything over to na...

The London Ruby User Group’s July meetup is this Monday, 13 July at 6:00pm at GoCardless’s offices near Farringdon and Barbican tube stations. Former-thoughtbotter Ismael Celis will talk about reactive command-oriented apps in Ruby, followed by me (Fritz Meissner) on fixing long-standing flakiness i...

Sally and Joël join forces to discuss the different ways to interpret the role of a ‘principle’ or ‘staff’ engineer, and the handwaving around what those titles mean in terms of the gradation.

We wanted to illustrate the difference between a vibe coded website and what a thoughtbot designer can produce. We also wanted to highlight the risk vibe coding poses to your business. So to demonstrate these points, we redesigned a vibe coded professional services website. Below are the before and ...

Roux is thoughtbot’s new CSS framework, created by Elaina Natario. Roux is being used by thoughtbotters and non-thoughtbot contributors. It’s simple and modern and we love it. But we still had an itch Roux didn’t scratch. thoughtbot developers and designers are looking for a component library we can...

With our 23rd anniversary happening this year, I’ve spent a lot of time thinking about what should happen to thoughtbot after I’m gone, and what the next generation of thoughtbot ownership and governance looks like. The most common path for companies like ours is to be sold to another consulting com...

Aji and Joël discuss graph and tree structures, their connection to the emergent properties, attributes and qualities found from a largely connected group of data.

You know the drill if you’ve validated the same rule on a few attributes. One presence validation is one matcher, and five of them turn into five nearly identical lines that don’t tell the next reader much: it { is_expected.to validate_presence_of(:first_name) } it { is_expected.to validate_presence...

Recently I stopped a group of flaky tests from running in CI. 60% of CI runs were failing because of this group, which was unsustainable. Three weeks later I was able to restore that group to CI, with 0% failures on main1 resulting. Our “non-flaky” tests now give more false positives than the (previ...

Playwright ships with a black-box recorder that records every detail of every test, giving you a treasure trove of information for debugging flaky tests. Most Rails apps I’ve worked on don’t use it. It’s called the Trace Viewer, and if you’re running Capybara with Playwright via playwright-ruby-clie...

Brighton Ruby 2026 will take place in a few days and the thoughtbot team will be there to meet you all in real life, learn from all the great talks, and enjoy a day by the English coast. We love Brighton Ruby and enjoyed it for many years. It is a single-day, single-track conference packed with grea...

Our hosts Chad and Sami team up this week to discuss AI code bases and whether they can be built to be developer friendly and with best practices in mind.

The checklist I expected Last week I attended a workshop on neuroinclusivity in learning design. I expected to come away with a checklist. Use larger fonts Send slides in advance Offer cameras off Use a dyslexia-friendly typeface Instead, the biggest takeaway was that there is no checklist. Hold on ...

Your most-viewed page might be one no human has ever opened. That is what AI crawlers have done to view tracking in 2026. I ran into this problem on a production app that needed engagement tracking. The first version tracked everything server-side, the way Rails apps have done analytics for years. I...

Aji and Sally are back together again, this time to discuss the different apps they use to make their workflows and To Do lists easier and quicker to achieve.

Stop. Right now, stop reading and take 2 minutes. Draw how to make toast. That’s it. No further instruction. No clarification. Just those words on repeat. “Draw how to make toast.” The moment you say it, something interesting happens. Everyone stops. Instantly engaged. Then the questions start. “Wha...

So one day a client came to me and said: “we want a Chrome extension.” Simple enough, right? First thing to know: the client didn’t want to build a real extension from scratch with its own codebase and logic. They wanted a wrapper, essentially their existing Rails app, dressed up and living inside a...

As AI-assisted software development becomes more widely adopted, more of the Ruby code in our Rails apps is being written by agents. Each team has its own conventions for how that code should look and behave, and we want those conventions enforced automatically rather than relying on the agent to re...

Our blog posts now have the option to Copy as Markdown to help our robotic friends more easily consume our content. (It’s just up there, below the title) Click the button and you will get this blog post copied to your clipboard in cleanly formatted Markdown. Then paste it into any prompt to give you...

Sally and Joël get technical as they lay out their thoughts on blog posts.

A few months ago we shipped a chat experience to production. Users ask a question, our app routes it through an LLM model, the model calls a few internal tools, and an answer comes back from it. It worked. Sort of. When the model answered well, we had no idea why. When it answered badly, we had no i...

Sometimes AI really does feel like magic, and right now just about any no-code app builder provides that magical experience for entrepreneurs with big ideas but no coding skills. You can spend half an hour typing a few details about your app into Lovable and create a simple, functional app with a po...

Welcome to another edition of This Week in #dev, a series of posts where we bring some of our most interesting Slack conversations to the public. Alternative Text for CSS-Generated Content Matheus Richard learned that the CSS content property accepts alternative text for screen readers, separated by...

The Giant Robots trio are back to discuss the development of thoughtbot’s ReadySetGo app, and whether AI might be causing developers to go backwards.

I ran HTML-validate and Axe core and a Claude prompt against a new website I’m building, and they caught a bunch of stuff I missed! This gave me a chance to remember the easily overlooked bits of building a website. And I visited a few dark corners of the HTML spec I hadn’t been to yet! Data attribu...
