Gitar checked October 1, 2026; Greptile checked October 1, 2026. Dollar figures and merge-gate behaviour should be re-read on the vendor pricing page before a contract.
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.
Greptile
A repository-context reviewer: the vendor describes a graph index and parallel review agents; credits are charged for completed reviews, not for keeping the graph.
Best for
- Teams whose defects are cross-file, not line-local
- Enterprises on Bitbucket Data Center, Gitea or Perforce
- Solo developers who can live on the free 50-credit Starter cap
- Early-stage startups that qualify for the 50% discount
Watch out
Each author has 50 included credits; balances are not pooled. Billing counts completed reviews, not PRs, and attributed CLI reviews share the user's seat/credits; unattributed API/CLI reviews bill as flex without creating an active-developer seat. Base/Plus/Apex use 1/3/10 credits, with $1 per additional credit. A flex-spend cap pauses overage reviews while authors with included credits can continue. Legacy T-Rex is also listed at 3 credits; do not mix its results with other tiers. The homepage lists GitHub, GitLab, Bitbucket and Cursor Origin; confirm the selected integration/deployment scope. Enterprise lists GHES, residency-enabled GitHub Enterprise Cloud, self-managed GitLab, Bitbucket Data Center, Gitea and on-premises Perforce P4.
