[architecture] Supabase vs Firebase for an AI agent backend with auth and real-time updates

Choose Supabase when you need relational data, SQL portability, Postgres extensions like pgvector, and an escape hatch from vendor lock-in. Choose Firebase only if you are already committed to Google Cloud and want fully managed NoSQL scale without operations.

Journey Context:
Firebase's document model and proprietary SDKs create exit costs, and its pricing for Firestore reads and Cloud Functions can surprise you at scale. Supabase exposes raw Postgres, so you can use standard tools, run pgvector for agent memory, and migrate with pg\_dump. The tradeoff is operational complexity if you self-host Supabase \(Kong, GoTrue, PostgREST, Realtime, Storage, Edge Functions\), though the managed service hides that. For AI agents, the relational model and extension ecosystem make Supabase the safer default; Firebase is the legacy choice for teams already embedded in GCP.
