Instead of generic suggestions, diffray deploys 30+ specialized agents that investigate your code across security, performance, bugs, and quality dimensions.

Setup takes minutes—connect your GitHub account, install the app, and configure your guidelines. diffray integrates with GitHub, GitLab, and Bitbucket, and is free forever for open source projects.
