Reviewers mostly see Supabase as a fast, practical way to ship products without piecing together separate backend tools. The repeated draw is real Postgres plus auth, storage, APIs, realtime features, and strong framework integrations in one place, with good docs, a clean dashboard, and less lock-in than Firebase. Users and founders alike say row-level security is especially useful, though it has a learning curve. The main complaints are around free-tier limits, some documentation gaps, edge-function cold starts, and a few rough edges in the dashboard UX.
