Reviewers see Supabase as a fast, practical way to launch products with Postgres, auth, storage, APIs, and realtime in one place. They repeatedly praise the clean dashboard, strong docs, easy framework integrations, and the sense of control that comes from using standard Postgres instead of a proprietary stack. Security features like row-level security get specific praise, though several users say RLS and some docs have a learning curve. A few also mention limits around the free tier, email sending, cold starts, and growing beyond built-in tools.
