FirestoreSequelize

FirestoreSequelize (v0.8.0) provides a Sequelize-like ORM for Google Cloud Firestore, enabling model definitions, queries (findAll, findOne, findOrCreate), subcollections, and sync operations. It wraps firebase-admin and supports TypeScript types. Key differentiators: intuitive API for developers familiar with Sequelize, automatic subcollection mapping, and schema sync. However, it is experimental (v0.x) with limited community adoption and potential breaking changes. Release cadence is irregular; last update was in 2021.
