Google's app platform: Firestore document database, auth, hosting, cloud functions, analytics, and push messaging. Strong realtime sync and offline support on mobile.

Reach for it when:
- Realtime chat and collaborative apps
- Mobile apps
- Rapid prototypes

Worth knowing: Proprietary and tied to Google Cloud; relational queries and migrations are harder than in SQL.
