Bundled features: Real-time sync Tight Firebase integration

What it is

Firestore is Google's document database with real-time sync as a primary feature. Tight integration with the Firebase platform — auth, storage, cloud functions, FCM. Generous free tier (1GB storage, 50k reads/day). The default for Firebase-stack apps.

Best for

  • Firebase-platform apps using auth + storage + functions
  • Mobile apps where Firestore SDK is the path of least resistance
  • Real-time-first apps (chat, collab, live updates)

When not to pick it

Skip Firestore for relational data — the document model fights against it. Skip if vendor lock-in to Google Cloud is a concern.

My take

Firestore is good for Firebase-stack apps. For non-Firebase projects, the lock-in is real and modern alternatives (Supabase, Convex) usually win.
