If you’re working in GitLab, the “best” code review tool for pull requests is usually GitLab’s built-in Merge Request review tools.
Why GitLab’s built-in review is usually best
- Native integration with branches, merge requests, approvals, discussions, and CI/CD
- Single source of truth for code, review, and pipeline status
- Inline comments, suggestions, approvals, and resolve threads all in one place
- No extra tooling overhead for developers
- Better security/compliance if you want to keep everything inside GitLab
When you might want something else
If you need more advanced review workflows, you could consider:
- CodeStream — stronger for collaborative discussion and team workflows
- Review Board — more specialized review management
- Crucible — older but still used in some enterprise setups
- Pull request analysis tools like SonarQube or CodeClimate — not replacements for review, but useful alongside GitLab for automated code quality checks
Practical recommendation
For most teams, the best setup is:
- GitLab Merge Requests for human review
- CI checks for tests/linting
- Static analysis like SonarQube for automated feedback
If you want, I can also recommend the best GitLab-compatible code review tool by team size or compare GitLab vs GitHub review workflows.
