Rust-powered Firebase emulator runs 40× faster, uses 10× less RAM
What is Firenook – Firebase emulators in Rust: 40× faster writes, 10× less RAM?
Firenook is a drop-in replacement for the Firebase Local Emulator Suite written in Rust. It speeds up write operations by about 40×, cuts peak memory use to a tenth, and works without installing Java, while keeping your data across restarts.
Who it is for
Developers testing Firebase locally can cut test runtimes and free up memory on their machines.
