Lovable auto-syncs every change to GitHub's main branch, but the sync can break if you rename the repo, force-push, or edit the same file on both sides. To prevent conflicts, always make changes in Lovable first and let the bot commit. If sync breaks, duplicate the project in Lovable and reconnect to a fresh repo.
How Lovable-GitHub Sync Works Under the Hood
Once you connect a Lovable project to GitHub, every prompt you send in Lovable triggers a commit to the main branch of your linked repository. Lovable uses a bot account (lovable-dev) to push these commits automatically — you do not need to click anything extra.
The sync is two-way: if someone pushes a commit directly to the main branch on GitHub, Lovable pulls that change into its editor. This means GitHub is the source of truth. If the same file is changed in both places before they sync, GitHub's version wins.
Sync only works on the main branch. If you create feature branches on GitHub, those changes do not appear in Lovable until they are merged into main. This is an important detail — it means you can safely experiment on branches without affecting your Lovable workspace.
The most common sync problems happen when users rename the GitHub repo, force-push to main, or make conflicting edits in both Lovable and GitHub at the same time. Understanding these failure points lets you avoid them entirely.
Prerequisites
- A Lovable project already connected to GitHub (see: how-to-connect-github-to-lovable)
- Access to both your Lovable editor and GitHub repository
- Basic understanding of what commits and branches are
Step-by-step guide
Verify the current sync status
Verify the current sync status
Open your Lovable project and click the GitHub icon in the top-right toolbar. If the connection is active, you will see the repository name with a green indicator. Next, open your GitHub repository in a new tab. Click the Code tab and check the commit history — the most recent commit should match the last change you made in Lovable. Compare timestamps to make sure commits are recent and not stale.
Expected result: The GitHub icon in Lovable shows a green connected state, and the latest commit in GitHub matches your last Lovable change.
Check for commit discrepancies
Check for commit discrepancies
In your GitHub repo, click the clock icon or the text that says 'X commits' near the top of the Code tab. This opens the full commit history. Scroll through and look for any commits NOT made by the lovable-dev bot — these are manual changes someone pushed directly to GitHub. If you see manual commits that happened after your last Lovable edit, those changes were synced into Lovable. If you see gaps where Lovable edits are missing, sync may have broken.
Expected result: You can see a clear timeline of lovable-dev bot commits matching your Lovable edits, with no unexplained gaps.
Prevent conflicts by editing in one place at a time
Prevent conflicts by editing in one place at a time
The number one rule for keeping sync stable: make changes in Lovable and let the bot push to GitHub. Avoid editing files directly on GitHub or via another tool while you are actively working in Lovable. If you must make a change on GitHub (for example, editing a README), do it when you are not sending prompts in Lovable. Wait for the GitHub commit to appear, then refresh your Lovable editor before continuing.
Expected result: Changes flow in one direction at a time — either Lovable to GitHub, or GitHub to Lovable — without overlapping edits.
Recover from a broken sync
Recover from a broken sync
If the GitHub icon in Lovable shows a red or disconnected state, or if commits have stopped appearing in GitHub for several edits, the sync is broken. The safest recovery method is: (1) In Lovable, click the three-dot menu on your project and select Duplicate. This creates a copy of your current project with all recent changes. (2) Open the duplicate project, go to Settings and then Connectors, and connect it to a brand new GitHub repository. (3) Verify the new connection by sending a test prompt and checking that a commit appears in the new repo.
Expected result: The duplicated project is connected to a new GitHub repo, and sync is working again with fresh commits appearing.
Set up commit notifications to monitor sync health
Set up commit notifications to monitor sync health
In your GitHub repository, click Settings in the top navigation bar. In the left sidebar, click Notifications (under Integrations). You can configure email notifications for pushes to the main branch. Alternatively, click the Watch dropdown at the top of the repo page and select 'All Activity' to get notified of every commit. This way you will know immediately if Lovable stops pushing commits.
Expected result: You receive email or GitHub notifications whenever a new commit is pushed to the repo, letting you spot sync failures early.

Why it's a problem: Renaming or moving the GitHub repository after connecting
How to avoid: Never rename the repo. If you already did, duplicate the Lovable project and connect to a new repo.
Why it's a problem: Force-pushing to the main branch on GitHub
How to avoid: Force-push rewrites history and breaks sync. Use normal commits only. Enable branch protection rules on main to prevent force-pushes.
Why it's a problem: Editing the same file in both Lovable and GitHub simultaneously
How to avoid: Edit in one place at a time. If you edit on GitHub, wait for the commit to sync to Lovable before making more changes.
Why it's a problem: Expecting changes on feature branches to appear in Lovable
How to avoid: Sync only works on the main branch. Merge your feature branch into main first.
Best practices
- Always make changes in Lovable first and let the bot push to GitHub — this is the intended workflow.
- Check the GitHub commit history at least once a week to verify sync is healthy.
- Never force-push to the main branch; enable branch protection rules to prevent this.
- Coordinate with teammates so only one person edits at a time to avoid conflicts.
- If sync breaks, duplicate the project and reconnect rather than trying to fix the broken link.
- Use GitHub's Watch feature to get notified of every commit and spot sync gaps early.
- Keep a changelog or notes about what you build each day so you can verify commits match.
Still stuck?

My Lovable project stopped syncing to GitHub three days ago. The GitHub icon still shows connected but no new commits are appearing. What steps should I take to diagnose whether this is a Lovable-side issue or a GitHub permissions issue?
Frequently asked questions
How often does Lovable sync to GitHub?
Every prompt you send in Lovable triggers an immediate commit to GitHub. There is no delay or batching — each change is pushed as soon as Lovable finishes generating it.
Can I use branches in GitHub with Lovable?
Lovable only syncs with the main branch. You can create branches on GitHub for other purposes, but Lovable will not see those changes until they are merged into main. Branch switching is available as an experimental feature in Settings, Account, then Labs.
What happens if I accidentally delete a file on GitHub?
Lovable will pull that deletion into its editor on the next sync. To undo it, use GitHub's commit history to revert the delete commit, and Lovable will pick up the restoration.
Does Lovable sync Supabase database changes to GitHub?
Lovable syncs migration files and Edge Function code to GitHub. However, actual database data, secrets, and environment variables stored in Lovable's Cloud tab do not sync.
Can the RapidDev team help recover a broken Lovable-GitHub sync?
Yes. RapidDev's engineering team has experience debugging broken Lovable-GitHub connections and can help you recover commit history or set up a clean reconnection.
Is there a limit to how many commits Lovable can push per day?
There is no hard limit on commits. However, each prompt costs credits, so the practical limit is your Lovable plan's credit allowance (100 credits/month on Pro, more on Business).
