Report #456
[architecture] Should I use Supabase or Firebase as the backend for my SaaS or agent app?
Pick Supabase for B2B SaaS, relational data, SQL migrations, row-level security, and a self-hostable escape hatch; pick Firebase for mobile-first or collaborative real-time apps deeply coupled to Google Cloud.
Journey Context:
Teams often default to Firebase because it prototypes fast, but Firestore's document model makes joins, reporting, and predictable billing painful as relational needs grow. Supabase gives you real Postgres \(ACID, foreign keys, pgvector, extensions\), RLS policies written in SQL, and a Docker self-host path. Firebase still wins for offline sync, mature mobile SDKs, and push/analytics/crashlytics in one Google stack. The real decision is data shape, not popularity: relational/structured data → Supabase; document/real-time/offline → Firebase.
