Good fit for Apps that can live with Postgres-shaped data — most Firestore use is shallow document storage that maps fine to a JSONB column or a relational schema.

Weak at Realtime semantics differ from Firestore's offline cache + listener model; client SDK swap is not transparent.

Replaces these SaaS

Firebase · Backend-as-a-service (auth + DB + storage + realtime)
Auth: export Firebase users via `firebase auth:export users.json` and import into Supabase Auth using the gotrue admin API or Supabase's `auth.users` SQL insert with the password-hash format documented in the Supabase migration guide. Firestore: write a one-off Node script using `firebase-admin` to read collections and `@supabase/supabase-js` to insert into Postgres tables (Firestore docs map to JSONB columns or normalized rows). Storage: download buckets with the Firebase CLI, upload to Supabase Storage with `supabase storage cp`.
