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 willing to let a bot apply fixes until the pipeline is green
- GitHub or GitLab shops evaluating a Sonar-owned reviewer
Watch out
Sonar acquired Gitar on 2026-05-21. Vendor says standalone Gitar keeps shipping with no change for current customers, and deeper SonarQube integration is the roadmap — confirm DPA, support entity, and whether you are buying Gitar, SonarQube, or both. Core/Pro stop at 50 users and pause automatic reviews when seat headroom is exhausted. Merge blocking is Pro, not Core. GitHub.com only — GitHub Enterprise Server is not supported; self-hosted GitLab is an Enterprise git-host option, not a self-hosted Gitar.
Greptile
The full-codebase reviewer: it spends credits to keep a graph of the repo, which is the point when bugs live in call sites the diff does not show.
Best for
- Teams whose defects are cross-file, not line-local
- Solo developers who can live on the free 50-credit Starter cap
- Early-stage startups that qualify for the 50% discount
Watch out
Credits run out: 50 standard reviews per seat, then $1 each, and TREX burns three credits. GitHub and GitLab only on the public pricing page. Confirm TREX vs standard before comparing catch-rate anecdotes from third-party blogs.

What is the hourly or throughput limit for Gitar vs Greptile?
Gitar: Manual “Gitar review” comments are unlimited. Core and Pro automatic-processing headroom (auto reviews and CI fixes) scales with assigned seats for the billing period; when it runs out, automatic reviews and fixes pause until the next period or you add seats. Vendor changelog: Pro gets double the per-seat review budget of Core — the numeric budget is not published. Enterprise: unlimited usage, no seat limits. REST API requests are rate-limited per organisation with an unpublished 429 threshold. After the 14-day trial, automatic processing stops; manual “Gitar review” still works. Greptile: No published hourly cap. Starter: 50 credits/month for one active developer. Pro: 50 credits included per seat/month, then $1 per extra credit. One standard review uses 1 credit; one TREX review uses 3.

Gitar: Yes. Greptile: Not verified. Autofix is still a suggestion until your CI and humans accept it.
