The Verdict
PostgreSQL is built for backend developers and enterprises, with a focus on sql-queries and json-support. Supabase targets developers and startups and leads with postgres-database and authentication.
PostgreSQL uses custom enterprise pricing, while Supabase starts at $25/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, PostgreSQL offers broader built-in capabilities (8 features vs 7), while Supabase takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
