I’m thrilled to see this project spring back to life and keep growing after its time away 😎

React Native Enterprise Framework is now open source! 🚀 We've built it as a drop-in replacement for Community CLI and for those who want to incrementally adopt React Native. ✨Features: ▪️Reusable cloud builds ▪️Novel Brownfield approach ▪️Self-hosted on your infrastructure

Been working with brownfield projects for a while, and had to build everything from scratch, each time. But that has changed since, react-native-brownfield 1.0 exists now: - Load SwiftUI and UIKit views - Load Jetpack Compose and Android views - Package everything More 👇

Fresh out of the oven!🥐 Just release React Native Paper 5.14.0! 👀 * `createMaterialBottomTabNavigator` is now deprecated– instead use `react-navigation/[email protected]` + `BottomNavigationBar` for a MD look! * support for `[email protected]` (10.x works the same way) ...👇

Not every NPM package can be trusted - supply chain attacks are real. DevTools plugins are no exception. That’s why I’m sandboxing each plugin in its own execution context 🫡

with new better models coming ever week, it's sucks that we can just one model in CLI tools... introducing zeroai 🔥 AI powered CLI app with support for any model, even including latest Grok! 👀 See the demo and sign up for the waitlist 👇

I'm excited to finally share: Rozenite, the React Native DevTools plugin framework, is launching early next week! 🎉 We're aiming for a Monday release, but no rest yet. I'll be pushing commits all weekend to make sure it’s rock-solid for anyone ready to try it out.

It was 9 years ago when I hired the then 3-person team of Callstack to help us serve $100MM revenue customers by bringing React Native to Windows 7/8 . The leadership I worked under were small-minded in many ways, but their ageism was shocking. “They look like Justin Bieber”. My

🚀 New in `react-native-sandbox`: isolated instances can now communicate directly via the `postMessage` API. The demo shows two sandboxes exchanging messages with dynamic whitelist, proving you can build secure multi-instance apps and micro-frontends in React Native. Follow

React Universe Conf | Sept 2-4, 2025 What a conference! Unique chance to learn, share, and be surrounded by innovators who are shaping the future.

🎉 PSA: First-class ArrayBuffer support is coming to TurboModules! No more base64 serialization. Massive performance wins for binary data! For an 8 MB payload, that means: - base64 → ~666 ms 🐢 - direct ArrayBuffer → ~1 ms 🚀 Huge 👏 to Kamil Paradowski for shipping this!

Enjoy faster Rock v0.11: - bundled create-rock for instant startup - improved fingerprints - iOS prebuilds by default

Run any model locally with React Native AI and AI SDK ⚡️

After 6+ years of failed experiments, it's finally working. Direct native API access from JS in React Native 🥹 Access the full iOS SDK – like a native dev. Cross threads – like a native dev. Today, my brother in JavaScript, you are a native dev.

We’re looking for a couple of senior React Native engineers to join the Callstack Engineers team! If you’d like to work with some of the best in React Native and make a real impact by shipping your code to billions of users, DM me. EU only.

It’s been a week since the transition of React and React Native to the React Foundation was announced. Proud that @Callstack is part of this change. As I meet with clients who’ve long wondered about the long-term support for advanced use cases within the React Native

I’ve always felt that testing native modules in React Native is overly complex. We had to rely on a mix of native and JavaScript tests with mocks which wasn’t ideal. Fortunately, we finally have a good solution for that.

There has been a healthy amount of interest in my React + Imgui + Static Hermes proof of concept, so I will write an in-depth article explaining everything: - The custom React renderer - Integrating Static Hermes in a runtime - event loop, polyfills, etc. - Zero-cost FFI
