Backend

Local Supabase dev, without Docker

One process, real Postgres, and the official supabase-js SDK works unchanged — REST, Auth, Storage and Realtime.

npm i tinbase

Runtime

A Linux-like OS that runs anywhere JS does

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

npm i lifo-sh

Bundler

React Native, bundled in your browser

browser-metro bundles React Native entirely in a Web Worker — any npm package, Expo Router, and real HMR, with no build server.

npm i browser-metro

Infrastructure

Run a thousand small apps on one box

A multi-tenant workload orchestrator. Gives every tenant a hostname, sleeps it when idle, and wakes it on the next request in about a second.

npm i orchd

Tooling

Low-footprint Expo dev servers

A Metro plugin and a thin dev server. Same-dep projects share one transform cache — ~40 MB per environment, not ~325 MB.

npm i jetplane
