Hey PH! 👋

I'm Sanket. I've spent years building tools for mobile app development, and one thing always frustrated me — the setup.

Want to try React Native? Install Node, install Xcode, configure Android Studio, set up an emulator... by the time you're ready to write your first line of code, an hour has passed. And that's if nothing breaks.

I built reactnative.run to fix that. Open a browser tab, start building, see your app instantly. That's it.

A few things that make it different:

Runs entirely in your browser — nothing to install, ever
Live preview — change your code, see it update in real time without losing your app's state
Real code — this isn't a toy. It generates production-ready React Native code you can export and ship
Free & open source — MIT licensed, no catch

We've been using this internally at RapidNative to power our own preview experience, and now it's available for everyone.

I'd love to hear:

What would you build first with this?
What's missing that would make you use it daily?

Give it a spin → reactnative.run/playground

We just launched and we're curious if you could open a browser tab right now and start building a mobile app with zero setup, what would you make? A side project? A quick prototype for work? A learning exercise? Drop your ideas below, we'd love to hear them.
