I built this after trying CodeRabbit, Greptile, and others. Same problems everywhere: can't customize what it checks, pricing per seat, black-box prompts.

diffray runs inside Claude Code or Cursor. Each "agent" is a Markdown file you can read and edit. Don't like how it checks for security issues? Change the prompt. Need a React-specific checker? Create one in 2 minutes. No API keys to configure — uses your existing subscription. npm install -g diffray && diffray review in any git repo.

Happy to explain the multi-agent architecture if anyone's curious.
