Lovable Cloud or Supabase: which one does your app use?
A Lovable app with logins or saved data has a Supabase backend. Either it is your own Supabase project, or it is Lovable Cloud, which Lovable runs for you on Supabase. The move is different for each, so check first.
Why it matters
| Your own Supabase project | Lovable Cloud | |
|---|---|---|
| Who runs it | You, at supabase.com | Lovable |
| In your Supabase dashboard | Yes | No |
| When you leave Lovable | It stays where it is | It moves to a Supabase project you own |
| Login settings | In the Supabase dashboard | In Lovable, More, Cloud, Users |
Check in Lovable
In your Lovable project open More, Cloud. If it shows screens to manage your database tables and users inside Lovable, it is Lovable Cloud. If it shows the Supabase icon and your Supabase project name, it is your own project.
Check in Supabase
Log in at supabase.com and look at your project list. If the project is there, it is yours. Lovable Cloud projects do not show up there.
Check in the code
Open the .env file in the repo. A supabase.co address that you can open in your own Supabase dashboard means it is your own project. Or ask Claude Code, Codex or Cursor:
Look at the .env file and the supabase folder. Tell me if this app uses its own Supabase project or Lovable Cloud, and how you know. Do not print any key.
Can Lovable Cloud stay?
Yes. Cloud can stay where it is while you build in Claude Code, Codex or Cursor, and even while you host the app somewhere else. It only has to move if you leave Lovable or want the backend in your own account.
