Reviewers see Supabase as a fast, practical way to launch products without piecing together a backend stack. The most common praise is its mix of Postgres, auth, storage, APIs, and realtime features in one place, plus good docs, a clean dashboard, and easy framework integrations. Users also like the open-source, low-lock-in feel, especially versus Firebase. The main knocks are smaller: RLS policies can take trial and error, some docs are hard to find, free-tier limits surface quickly, and a few users mention cold starts or wanting more flexible mid-tier pricing.
