Show HN: Firenook - Firebase emulators in Rust: 40× faster writes, 10× less RAM
Firenook runs the Firebase emulators with your firebase.json, SDKs and ports: 40× faster writes, 10× less memory, no Java, and data that survives restarts.
Quick read
Firenook is a drop-in replacement for the Firebase Local Emulator Suite that runs native emulators without Java, using your existing firebase.json, SDKs and ports. Visit to get much faster local emulation with persistent data, lower memory use, and a fuller console for inspecting calls and state.
- Runs Firestore, Auth, Storage, Functions, Pub/Sub, Tasks, Eventarc
- Data survives restarts with fast keep-data import/export
- Same ports/flags/format so it fits existing workflows
