StackMatch Editorial verdicts
Bylined · No vendor influenceSupabase is the open-source Firebase that engineers actually want — Postgres-native, generous free tier, RLS done right. The platform is opinionated in productive ways and the lock-in is genuinely lower than the competition.

Side-by-Side Comparison
Objective metrics, no spin.
Web and mobile apps that want a full backend without building auth, storage, and APIs from scratch — especially strong for AI apps needing pgvector.
Complex enterprise workloads requiring fine-grained Postgres tuning — raw RDS or self-managed Postgres gives more control.
Teams running large MySQL-compatible workloads that have outgrown a single primary and want safe, branchable schema changes.
Cost-sensitive small projects — the minimum pricing and lack of a free tier make it hard to justify for side projects.
