Lovable GitHub sync not working
Lovable GitHub sync is powerful because it gives your project version control, backups, and deployment options. When sync breaks, the cause is often repository permissions, a renamed or moved repo, branch conflicts, GitHub app access, or deployment configuration.
Quick verdict
If Lovable GitHub sync stops working, check repository location, permissions, default branch, recent commits, and whether the Lovable GitHub app still has access before making code changes.
Target topics covered
Common sync failure causes
Lovable's GitHub integration depends on the exact connected repository and permissions. Renaming, moving, deleting, or changing access to the repository can break the connection.
- Repository was renamed, moved, archived, or deleted
- GitHub app permissions changed
- Default branch changed unexpectedly
- Manual commits conflict with Lovable edits
- Deployment platform is watching the wrong branch
- Secrets or environment variables exist in hosting but not locally
Check before reconnecting
Before disconnecting anything, confirm the current GitHub repo, owner, branch, and latest commits. Disconnecting and reconnecting can create a new repository depending on the situation, so review the current setup first.
Deployment and GitHub are separate
A GitHub sync can work while a Vercel or Netlify deployment still fails. If the repo updates but the website does not, inspect deployment logs and environment variables in the hosting platform.
GitHub sync prompt
Lovable is not syncing with GitHub. The connected repo is [repo]. The latest expected change is [change]. Please inspect sync settings, repository access, default branch, recent commits, and deployment assumptions. Do not disconnect or recreate the repo unless absolutely necessary.
Frequently asked questions
Why is Lovable not syncing to GitHub?
Common reasons include changed GitHub permissions, renamed or moved repositories, branch conflicts, deleted repos, or the deployment platform watching a different branch.
Can I rename a GitHub repo connected to Lovable?
It is safer not to rename, move, or delete a connected repo because the integration depends on the stable repository path and permissions.
Why did GitHub update but my website did not?
The deployment platform may have failed to build, may be using the wrong branch, or may be missing required production environment variables.
