Show HN: Firenook – Firebase emulators in Rust: 40× faster writes, 10× less RAM
Firenook is a drop-in replacement for the Firebase Emulator Suite, rebuilt as a single Rust engine without Java dependencies and with a new web-based console UI. The authors claim 40× faster writes and 10× less RAM, running 2 million records in about 2GB versus 22GB for the official suite. It was developed over roughly two months and dogfooded internally for a month before release, and the authors acknowledge it is still incomplete.
What this means for indie developers：Indie developers using Firebase as a backend can try it locally to avoid out-of-memory issues and data loss during large-data debugging, while verifying compatibility for their own projects.
