Code Review Tools

Haystack helps engineering teams manage the growing volume of AI-generated pull requests. It sits on top of GitHub, analyzes each PR’s diff, codebase context, agent trace, intent, and verification evidence, then routes it: safe to move forward, needs fixes, or needs human review. Teams use Haystack to keep code moving without rubber-stamping, focusing human attention where judgment actually matters.
