Fireblaze

Fireblaze is a schema migration tool for Firestore, forked from the unmaintained fireway. Current stable version is 1.4.0. It provides a CLI for managing Firestore schema changes with deterministic migration ordering using semantic versioning. Supports JavaScript, TypeScript (via ts-node), and JSDoc-typed migrations. Key differentiators include async migration support, dry-run mode, emulator compatibility, and typed migration options. Release cadence is low; last update was in early 2024.
