Haystack – Review the PRs that need human attention

Haystack is a developer tool that replaces GitHub’s pull request review system with a triaged queue, designed for engineering teams overwhelmed by the surge of PRs from coding agents. It automatically prioritizes and surfaces only the pull requests that truly need human attention, saving reviewers time and reducing bottlenecks. The project is interesting because it addresses a growing pain point in modern software development—managing AI-generated code contributions at scale.
