How to Integrate GitLab with V0

The first step is getting your V0 project into GitHub, which is the only Git platform V0 natively supports. If you have already done this, skip to step 2. If not, here is how it works. Open your V0 project and look for the Git panel icon in the left sidebar — it looks like a branching diagram. Click it to open the Git panel. If you have not connected GitHub to V0 yet, you will see a prompt to authorize GitHub via OAuth. Click through the authorization flow and grant V0 the permissions it requests to create repositories and push code. Once connected, the Git panel will show an option to create a new GitHub repository for your project. Enter a descriptive name for the repository — something like my-startup-app or portfolio-v2. Choose whether it should be public or private. Click create. V0 will create the repository on GitHub under your account and push your entire current project as the initial commit to the main branch. Verify this worked by going to github.com and checking your repositories — you should see the new repository with your V0 project code. At this point, V0 is connected to GitHub and any future AI generation sessions will push to branches in this repository named v0/main-{hash}. This is your source of truth for the V0 workflow.

Now create a GitLab repository that will mirror your GitHub repository. Log in to GitLab and click the New Project button (the + icon in the top navigation or from your dashboard). Select 'Create blank project' — give it the same name as your GitHub repository for clarity, and choose the appropriate visibility (Public or Private). Click Create project. With the GitLab repository created, set up pull mirroring. Go to your GitLab repository, click Settings in the left sidebar, then click Repository. Scroll down to find the Mirroring repositories section and click Expand. In the 'Git repository URL' field, enter your GitHub repository URL in the format: https://github.com/your-username/your-repo-name.git For the 'Mirror direction', select 'Pull' — this means GitLab will pull from GitHub, not push to it. For authentication, select 'Password' and enter a GitHub Personal Access Token in the password field. Generate a GitHub PAT at github.com/settings/tokens/new — select 'repo' scope (read access to your private repositories) and copy the token. Back in GitLab, paste it as the password. Check the 'Mirror branches' option if you want all branches (not just main) to be mirrored. Click 'Mirror repository' to save. GitLab will immediately attempt the first sync, and you will see a status indicator showing when the last sync occurred. By default, GitLab checks for new commits from GitHub every 5 minutes. You can also trigger a manual sync by clicking the sync icon next to your mirror configuration.

Before setting up CI/CD, confirm the mirror is working correctly. In your GitLab repository, click the Repository tab and view the list of commits. You should see the same commit history as your GitHub repository. The commit messages and timestamps should match. If the sync shows an error, the most common cause is an expired or incorrect GitHub Personal Access Token. Go back to GitLab Settings → Repository → Mirroring repositories, check the error message displayed next to your mirror, and update the token if needed. GitHub PATs can expire (if you set an expiration during creation) or be revoked. For private repositories, double-check that your GitHub PAT has the 'repo' scope enabled — this grants read access to private repositories. The 'public_repo' scope is only sufficient for public repositories. To test that new V0 changes sync correctly, go back to V0 and make any small change — even just a comment in a file. Push from V0 to GitHub. Wait 5-10 minutes, then check your GitLab repository to confirm the new commit appeared. If it syncs correctly, your workflow is set up: V0 → GitHub → GitLab (auto-mirror). From GitLab's perspective, it looks like you are pushing to GitLab directly.

Now that GitLab is receiving your V0 code via the mirror, you can set up CI/CD pipelines. GitLab CI is configured through a file called .gitlab-ci.yml in the root of your repository. You need to add this file to your GitHub repository (not directly to GitLab, since GitLab's copy is read-only via mirror), push it from V0 or a local editor, and it will appear in GitLab after the next mirror sync. A basic .gitlab-ci.yml for a V0 Next.js project should define stages: install dependencies, run type checking (tsc --noEmit), and optionally deploy to Vercel. For Vercel deployment from GitLab CI, you need a Vercel API token — generate one at vercel.com/account/tokens and store it in GitLab as a CI/CD variable. In GitLab, go to Settings → CI/CD → Variables and add VERCEL_TOKEN with the token value, marked as Protected and Masked. The CI/CD pipeline runs automatically whenever GitLab receives a new commit from the GitHub mirror. This means every V0 push to GitHub that eventually mirrors to GitLab triggers your pipeline. The pipeline provides an additional safety net of checks beyond just Vercel's build — you can add linting, testing, accessibility checks, or security scanning. Note that since GitLab's mirror is read-only, you cannot push changes from GitLab back to GitHub. GitLab CI can deploy to external services (like Vercel), but any code changes must originate from V0 or from direct pushes to the GitHub repository.

Running two repositories requires a clear mental model to avoid confusion. The key rule is: GitHub is the source of truth. V0 pushes to GitHub. Developers with write access push to GitHub. Pull requests are reviewed and merged on GitHub. GitLab is a read-only mirror that receives copies of commits and runs pipelines. Never commit directly to the GitLab repository — it is a one-way mirror and any commits made directly to GitLab will not appear in GitHub and will eventually be overwritten when the mirror syncs. All code changes go through V0 or through direct GitHub pushes. For teams using GitLab for issue tracking or project management alongside GitHub for code, this separation can feel awkward. Some teams prefer to use GitHub Issues for V0-related tasks and only use GitLab for the CI/CD pipeline execution. Others use GitLab for issue tracking and link issues to GitHub commits manually. When a GitLab pipeline fails (for example, a type error in V0-generated code), the fix must be made in V0 or via a direct commit to the GitHub repository. Push the fix to GitHub, wait for the GitLab mirror to sync (up to 5 minutes), and the GitLab pipeline will automatically re-run on the new commit. You do not fix CI failures in GitLab directly.
