Spent all week with 37 Claude agents grinding in parallel, 18 hours a day, until they fully reverse engineered @expo. sharing the results so you don’t have to burn the tokens. 100% free and open-source: github.com/expo/expo

We just shipped an updated T3 Code Stable release with over 1,400 changes 🤯 Quick highlight reel of my favorites: - Massive perf wins on desktop and mobile - Add a project to another machine from the "Run on" menu - EAS Simulator remote hosts for iOS dev - PR diffs now show code vs tests vs docs at a glance - Idle Claude threads compact early so the cache stays warm (beta) - Mobile got a big native pass. It finally feels native - `t3 doctor` can reclaim database space - `t3 connect` now checks your machine is reachable, and errors say how to fix them - Webhook tasks got filters and dedupe - Skill discovery is much more reliable - Tons of Windows, terminal, and scroll fixes Least favorite: I caved, LaTeX renders on web and mobile Also heads up, we're getting a bit more experimental with how we treat Nightly, so now would be a good time to move back to stable :)

Let us know if anything's hard to do when adapting your app for iPhone Duo in SDK 58! - Expo Router and UI get you 90% there - You may need extra SafeAreaViews for custom content - Do test the split left layout!

shouting into the void here, I guess… but if you look at this and think it's time to dunk on this, think again: a huge chunk of teams choose to use Electron. by miles. the cheat sheet to this tweet is simply, there's more viable options than just Electron.

SDK 58 is out 🙌 This SDK is built for iOS 27. Apps on SDK 58 will be ready for Duo on day one 📖. The release also includes App Intents for Siri, 2x faster clean Android builds, faster Expo modules, and a CLI built for your coding agent.

Git Merge 2026 is wrapping up today! I'm not in Lisbon myself, but I made something for the occasion. Introducing: 🗺️ Git Atlas - an interactive guide through Git features across Git releases over the years. It allows you to investigate the evolution of this beloved tool. Git is 21 years old this year and still kicking - it's still at the core of software engineering.

expo-device-hub, new from @expo, turns your browser into a local device dashboard 📱 - live stream of every iOS sim + Android emulator - tap, swipe, scroll, type in the page - boot and shut down without Xcode or Android Studio - flip dark mode, and more bun expo install expo-device-hub, then bun expo start. The link prints in your terminal :)

Today was my last day at Meta - 5 years with the React team has been incredible. Tomorrow is my first day at @expo - so excited to be putting 100% into building for the builders. Onward! 🚀

maybe too early to share, but this is project "noxcturnal" for the expo cli and what it does to our largest testing app's cold bundling times 🚀 (2-3x speedup)

"#UXDesign is my passion" ahh vibe

what if openai made a taxi meter for your codex sub?

tomorrow it's time for the React Native London meetup 🥳 (don't miss @zoontek's @expo ui talk 🫶)
