Gitar
A reviewer that treats a red build as the job: comments, then fixes, then re-runs CI. Distinct from comment-only bots.
Best for
Teams that want CI failure analysis next to the review
Orgs evaluating supervised bot fixes and CI verification
GitHub or GitLab shops evaluating a Sonar-owned reviewer
Watch out
Core/Pro are capped at 50 users; Enterprise allows unlimited users and is priced by PR outcome, with unlimited iterations per PR. The vendor says Enterprise has no rate limits; it does not publish a Core/Pro automatic-review allowance on the sources checked. Merge blocking is Pro, not Core. Gitar supports GitHub, GitLab, Bitbucket and Azure DevOps, including self-hosted code-hosting instances; this does not establish that the Gitar service itself runs on-premises.

Graphite
