About Greptile

Greptile is the AI code review platform that builds a graph index of your entire codebase, then runs a swarm of agents to catch issues humans miss. Version 4 (2026) uses Anthropic’s Claude Agent SDK for autonomous investigation, with lower false-positive rates than v3. Pricing shifted in March 2026: $30/seat/mo includes 50 reviews, then $1/review after — the only AI code review tool with per-review billing. Free for open-source. GitHub + GitLab only, self-hosted enterprise option available. ‘Merge 4x faster, catch 3x more bugs’ is their headline claim.
