Lovable to Supabase Migration
A migration from Lovable or Lovable Cloud to Supabase makes sense when the product already works and needs more control over data, permissions, infrastructure, code, and deployment.
A good migration is not only moving tables. It is moving a working product into infrastructure that can be maintained, tested, and extended.

When is migration the right move?
Lovable can be a fast way to reach a working version. Moving to Supabase becomes important when there are real customers, backups, complex permissions, integrations, performance needs, ownership of data, or a more structured development process.
Supabase is based on Postgres and adds Auth, Storage, Edge Functions, and project management tools. That makes it a strong foundation for a product that needs to move from demo to stable business system.
What should be checked before migration?
Review the data model, users, permissions, files, APIs, payments, key screens, and business workflows. An unplanned migration can break login, expose the wrong data, or lose records.
In Supabase migrations, roles, users, permissions, and Row Level Security do not always migrate automatically. They should be configured and tested after the move.
How does Itay Karkason handle this migration?
Itay Karkason starts by mapping the product and data, builds a clean Supabase target, moves data in stages, connects the application, and then tests the business-critical scenarios. The goal is a clean move without data loss and without turning the product into an endless rebuild.
Lovable Cloud vs. your own Supabase project
Lovable Cloud runs on Supabase, but the project is managed in Lovable’s account and does not appear in your Supabase Dashboard. You do not get direct access to the SQL Editor, logs, backup settings, or the database billing plan.
A Supabase project you open yourself gives full ownership: data access, backups, monitoring, permissions, and plan choice. Lovable Cloud wins on speed; a product with paying customers is usually better on a database you own.
How to move from Lovable Cloud to Supabase without losing data
Lovable Cloud has an official database export (Cloud > Overview > Advanced settings). It is a Postgres dump with the schema, data, functions, triggers, RLS policies, bucket definitions, cron jobs, and the auth tables including password hashes, so users can keep logging in with the same password. Not included: the Storage files themselves, secrets and API keys, and Google or GitHub OAuth settings.
The order of work: 1. Make sure the project is connected to GitHub and inventory tables, files, Edge Functions, secrets, and login providers. 2. Export the database and download every Storage file. 3. Open an empty Supabase project. 4. Restore the dump with pg_restore 16 or newer. 5. Create the buckets, upload the files, and run a script that rewrites old file URLs stored inside tables. 6. Deploy Edge Functions from the repo, re-enter every secret, and update redirect URLs with the OAuth providers. 7. Compare source and target: row counts per table, users, files, and no leftover old URLs. 8. Only then point the app at the new project and remove Lovable Cloud.
What breaks most often: removing Lovable Cloud before downloading the export and files; broken images from old URLs inside the data; Edge Functions that deploy but fail on a missing secret; a Stripe webhook returning 401 because of the verify_jwt setting; and Google login failing because the redirect URL was not updated. At the time of writing, exports are capped at 5GB and one export per 24 hours. The interface changes, so check Lovable’s current documentation before starting.
Components to Plan
Users and permissions
Who logs in, what each user can see, and how that is tested.
Business continuity
Reducing downtime, data loss, and broken workflows.
Testing
Login, create, edit, payments, reports, and central screens.
Frequently Asked Questions
Does everything need to be rebuilt?
Not always. Sometimes the data and auth infrastructure can be replaced; sometimes parts of the code should also be cleaned.
Is Supabase suitable for a business product?
Yes, if schema, permissions, backups, and tests are planned correctly.
Can a Lovable Cloud project be moved to Supabase in one click?
Not in one click. There is an official database export, but files, secrets, OAuth settings, and Edge Function deployment are done by hand.
Will users have to reset their passwords?
With the full official export, no: password hashes come along. If users are moved through CSV or an API, hashes do not come along and a password reset flow is needed.
What is the most dangerous mistake?
Removing Lovable Cloud before downloading the export file and all Storage files. After removal, access to the backup is gone.
