Codex Cloud Adds GitLab Support (Beta)

CodexView original changelog

OpenAI extended Codex cloud with GitLab support in beta, available on every ChatGPT plan. Users can connect a GitLab project to Codex cloud, spin up an environment for it, and launch tasks directly from GitLab issues or merge requests — including automatic merge request reviews. The integration brings GitLab feature-parity with GitHub, which was previously the only natively supported code host for Codex cloud.

Key Takeaways

  • GitLab integration reaches beta on every ChatGPT plan, from Free through Enterprise, removing the GitHub-only limitation that has defined Codex cloud since launch.
  • Tasks can be started two ways: directly inside Codex, or by mentioning @codex inside a GitLab issue or merge request.
  • Codex can perform one-off or continuously automatic merge request reviews, mirroring the automatic PR review workflow already available on GitHub.
  • Self-managed and dedicated GitLab instances are supported, but require admin-configured webhooks and GitLab 19.0 or later for @codex-triggered activity.
  • Workspace admins retain a kill switch — the GitLab connector can be disabled entirely for a workspace.
  • The move is particularly significant for regulated industries and European teams that rely on self-managed GitLab for data-sovereignty reasons and previously had to rely on GitLab's own DIY MCP server to reach Codex.

GitLab Joins Codex Cloud

OpenAI has extended Codex cloud with beta support for GitLab, closing a long-requested gap for teams whose codebases live outside GitHub. The integration is available on every ChatGPT plan, from Free through Enterprise, and lets users connect a GitLab project to Codex cloud the same way they would connect a GitHub repository.

How It Works

Once a GitLab project is connected, users can create a dedicated Codex cloud environment for it and start tasks in two ways: directly from the Codex interface, or by mentioning @codex inside a GitLab issue or merge request. Codex can also be asked to perform a one-off or continuously automatic review of new merge requests, mirroring the automatic PR review workflow Codex has offered on GitHub since earlier this year.

Self-Managed and Enterprise Considerations

For organizations running self-managed or dedicated GitLab instances, workspace administrators need to configure the connection themselves, and GitLab-triggered activity (like @codex mentions) requires webhook access and GitLab 19.0 or later. Workspace admins retain the ability to disable the GitLab connector entirely if they don't want it available to their team.

Why It Matters

Until now, Codex's built-in code-hosting integration was GitHub-only — the only way to reach GitLab-hosted code was through GitLab's own MCP server, a more manual, DIY setup. Native GitLab support removes that friction and opens Codex cloud to a large segment of engineering teams, particularly in regulated industries and Europe, that rely on self-managed GitLab for data-sovereignty reasons.
