Gitar

Gitar is an agentic AI code review tool that comments on pull requests and also generates and applies fixes, validating each change against CI with full codebase context. It can root-cause CI failures, iterate on fixes until the build passes, and manage the pull request lifecycle from block to approve to merge. It integrates with GitHub, GitLab, Jenkins, CircleCI, Buildkite, Slack, Jira, and Linear.
