# GitLab integration with Sourcegraph

You can use Sourcegraph with [GitLab.com](https://gitlab.com) and GitLab CE/EE. Read a high-level overview of how Sourcegraph and GitLab work together in our [GitLab solution brief](https://about.sourcegraph.com/guides/sourcegraph-gitlab-solution-brief.pdf).

## Repository syncing

Site admins can [add GitLab repositories to Sourcegraph](/admin/code-hosts/gitlab#repository-syncing).

## Repository permissions

Site admins can [configure Sourcegraph to respect GitLab repository access permissions](/admin/code-hosts/gitlab#repository-permissions).

## User authentication

Site admins can [configure Sourcegraph to allow users to sign in via GitLab](/admin/code-hosts/gitlab#user-authentication).

## GitLab UI native integration

GitLab instances can be configured to show Sourcegraph code navigation natively. See the [GitLab integration docs](/admin/code-hosts/gitlab#native-integration) for how to enable this on your GitLab instance.

## Browser extension

The [Sourcegraph browser extension](/integration/browser-extension) supports GitLab. When installed in your web browser, it adds hover tooltips, go-to-definition, find-references, and code search to files and merge requests viewed on GitLab.

1. Install the [Sourcegraph browser extension](/integration/browser-extension).
1. [Configure the browser extension](/integration/browser-extension#configuring-the-sourcegraph-instance-to-use) to use your Sourcegraph instance.

-   You can also use [`https://sourcegraph.com`](https://sourcegraph.com) for public code from GitLab.com only.

1. To allow the browser extension to work on your GitLab instance:
    - Navigate to any page on GitLab.
    - Right-click the Sourcegraph icon in the browser extension toolbar.
    - Click "Enable Sourcegraph on this domain".
    - Click "Allow" in the permissions request popup.
1. Visit any file or merge request on GitLab. Hover over code or click the "View file" and "View repository" buttons.
