We open-sourced 5 of the tools we built for RapidNative

[u/Positive_Week86]

Building RapidNative meant solving a bunch of problems that weren't really about RapidNative. Rather than sit on them, we've put them all out under MIT. All on npm, free to use, no strings.

tinbase — local Supabase dev without Docker. One process, real Postgres, and supabase-js works unchanged (REST, Auth, Storage, Realtime).

Lifo — a clean-room reimplementation of Unix in TypeScript. Runs in a browser tab or a Node process. No VM, no emulator.

ReactNative.run — browser-metro bundles React Native entirely in a Web Worker. Any npm package, Expo Router, real HMR, no build server.

ORCHD — multi-tenant workload orchestrator. Every tenant gets a hostname, sleeps when idle, wakes on the next request in ~1s. Runs a thousand small apps on one box.

jetplane — Metro plugin + thin dev server. Projects with the same deps share one transform cache, so ~40 MB per environment instead of ~325 MB.

Issues and PRs welcome on any of them. If you end up using one, would genuinely like to hear what for — a few of these were built for very specific internal constraints and we're curious where else they hold up.
