Gitar

Gitar is an AI code review and CI fixing agent that works directly inside pull request workflows on GitHub and GitLab. Built by the team behind Uber's development stack, it automatically reviews code changes for security vulnerabilities, bugs, performance issues, and code quality, then pushes actual fixes to the branch rather than just leaving comments. It also analyzes CI failures, deduplicates flaky test noise, and iterates on fixes until pipelines pass — all without requiring developers to leave their PR interface.
