Top 18 Code Review Tools for GitLab in 2026

GitLab's review workflow is built around the merge request (MR) rather than the pull request, and its CI/CD pipelines are native to the platform rather than a bolted-on integration. Tools built for GitLab typically post findings as MR discussion threads and can participate directly in pipeline stages, rather than only reacting to a webhook after the fact.

GitLab also ships a broad set of security scanning natively, with SAST, dependency scanning, secret detection and more built into GitLab Ultimate. As with GitHub, that changes the calculation for a third-party tool: the question is often less "can it reach GitLab" and more "does it do something GitLab's own scanning doesn't."

Top 18 code review tools for GitLab

Every tool in the directory documented as integrating with GitLab, 14 fully, 4 partially.

Support is not the same as parity, since some integrations are narrower in scope or gated to a higher plan tier. Tools with full support are listed before those with partial support.

What to look for

• Whether findings appear as MR discussion threads or only in a separate dashboard
• Whether the tool runs as a pipeline job (full log/artifact access) or purely via API/webhook
• Overlap with GitLab Ultimate's built-in SAST, dependency and secret scanning
• Support for merge trains and approval rules, if your team uses them
