Reviewers mostly see Supabase as a fast, reliable way to ship a real backend without managing much infrastructure. The recurring praise is the all-in-one stack: Postgres, auth, storage, realtime, APIs, and edge functions in one place, with strong docs, a clean dashboard, and less vendor lock-in than Firebase. Users and founders alike say it saves major setup time and scales well, especially for small teams. The main caveats are some learning curve around RLS and auth, uneven docs in places, cold starts, and limits on the free tier.
