Supabase
Open-source Firebase alternative with PostgreSQL, pgvector for vector storage, Edge Functions (Deno) for serverless AI logic, and real-time subscriptions. Popular backend for agents needing persistent state, vector retrieval, and auth.
Solid choice for most workflows
You need a scalable backend for agents with persistent PostgreSQL storage, vector search, authentication, and real-time updates without vendor lock-in.
Blazing fast setup for prototypes, scales to 12K pooled connections and 60TB storage; most apps hit query/schema limits before platform caps. Reliable for agent state but optimize indexes heavily.
You want to deploy agent backends across multiple environments (dev/staging/prod) with CI/CD and preview branches.
Ephemeral branches spin up in seconds for testing; production deploys are atomic via migrations. Handles 40+ engineers contributing infra at Supabase-scale.
Your agents need low-latency serverless compute tied directly to your database for AI workflows.
Excellent for lightweight AI tasks and webhooks; scales automatically but watch Deno limitations on heavy compute.
Supabase wins on SQL power, openness, and agent-friendly vectors—Firebase for pure NoSQL speed.
Pick Supabase when you need relational data, pgvector RAG, or to avoid Google's lock-in.
Pick Firebase for schemaless NoSQL, massive free tier, or when you're all-in on Google ecosystem.
Connection limits bite fast
Direct connections cap at 60-500 by tier; use pooled connections (up to 12K) for agents. Most perf issues are unoptimized queries/indexes, not raw limits—profile early.
