[architecture] Choosing between Supabase and Firebase for a new full-stack app's backend

Pick Supabase when you need a relational model, complex queries/transactions, predictable tiered pricing, EU data residency, and an escape hatch to self-host; pick Firebase when you need NoSQL flexibility, Google's marketing/ad integrations, or battle-tested real-time sync with minimal schema design.

Journey Context:
Many teams default to Firebase because of the generous Spark tier and mature mobile SDKs, then hit a wall when relationships, JOINs, or egress costs grow. Supabase is PostgreSQL under the hood, so row-level security, vector extensions \(pgvector\), and SQL migrations are first-class. Firebase Firestore scales reads/writes horizontally but pricing is per-document and can spike with listeners; Supabase charges by compute/storage and does not bill per API request. Supabase self-hosting via Docker is supported; Firebase cannot be self-hosted. The common mistake is choosing based on the free tier alone instead of data-model fit.
