Greptile
AI code review agent that indexes your repository and analyzes PRs in depth by tracing dependencies between files
Overview
Greptile is an AI agent specialized in code analysis and review that indexes your entire repository by building a complete dependency graph between files and modules. Instead of simply scanning PR diffs linearly, the tool performs deep multi-hop analysis: it traces function calls, consults Git history to understand change patterns, follows imports between files and automatically discovers potential side effects that manual review would miss. The Developer plan (free) allows basic use without commitment. The Pro plan ($30/developer/month) includes 50 reviews per month with $1 billing per additional review beyond quota.
Enterprise on request offers self-hosting, SSO/SAML, custom DPA and the ability to provide your own LLM to keep data internal. Greptile offers generous discounts for qualified open-source projects and pre-Series A startups. The interface remains English only, with no official French support announced. The main strength is that Greptile automatically discovers hidden regressions and potential bugs that basic manual review would miss through dependency traceability. The weakness is that per-developer pricing can become heavy for a very small team or project with infrequent PRs.
Our verdict
Best for mid-sized development teams wanting to industrialize code review quality and detect hidden regressions that basic diff analysis would miss. Not for you if your team is very small (under 3 developers) or your technical stack is very simple: the per-developer and per-review cost does not justify gains if PRs are few and not complex.
