As answered by people managing CodeSandbox and Reeve.page.
Reeve.page's answer:
People who built a real app with Lovable, Bolt, v0, Cursor, Replit, Windsurf, Claude, Codex on Supabase, with users and data in it, and who are not database engineers. Also small studios and freelancers who build these apps for clients and look after them after handover.
Reeve.page's answer:
Reeve is built for one stack: apps made with AI builders on Supabase. The scanner knows which keys belong in a frontend (the Supabase anon key) and which are a real leak (a service_role key), so its report stays short and worth acting on. The backups are checked and encrypted: every copy is read back before it counts, kept outside Supabase, and put back with one button after a safety copy of today is saved.
Reeve.page's answer:
Reeve covers both halves in one place. It finds what is exposed in your app, and it keeps copies you can put back with one button. The backups include your users' uploaded files, and everything is explained in plain language for someone who has never opened the Supabase console.
Reeve.page's answer:
Reeve started with a pattern. Apps built with AI tools kept going live with the same short list of mistakes: secret keys in the frontend, database tables anyone could read, storage buckets open to the internet. Their owners had nobody watching after launch, and Supabase's free plan keeps no backups at all. Reeve is that somebody: a free scan to see where you stand, then care that watches the app and keeps a copy you can restore.
