Greptile

Greptile is an AI code reviewer that indexes a whole codebase as a graph and uses a swarm of agents to review and test every pull request.

Greptile reviews pull requests with the full context of a repository. It builds a graph of the codebase's files, functions and dependencies, then runs parallel agents that review each change, assess its impact beyond the diff and flag issues from style violations to security risks and multi-file logic bugs. It learns a team's coding standards by reading engineers' PR comments, and teams can write their own rules in plain English. Found issues can be sent with one click to Claude Code, Cursor, Codex or Devin to fix, and a Greptile MCP server connects it to other agents. Starter is free for one developer with 50 monthly credits, Pro costs $30 per seat, Enterprise adds self-hosting, and open-source projects can use it free.
