Haystack triages incoming pull requests so teams can focus on the ones that need attention instead of manually checking every change.
Haystack
Freemium
Haystack is an AI-powered code review tool for pull request workflows. It helps teams triage PRs, surface risky changes, and route reviews using captured decisions, ownership, and context.
What is Haystack?
Haystack is an AI-powered code review product for pull request workflows. Its homepage describes it as the fastest path from pull request to merge, and the product copy focuses on helping teams review changes in logical order while keeping attention on the PRs that actually need human judgment.
The product watches for design decisions, risk policies, and ownership rules that matter in a codebase. It can capture reasoning from coding-agent sessions, flag PRs that appear to reverse those decisions, and guide reviewers toward the right person or the right context before a risky change merges.
What can Haystack do?
Decision-aware review
The product compares PRs against captured decisions, risk policies, and ownership rules, then flags changes that appear to reverse prior choices.
Review routing by ownership
When a PR needs a person, Haystack can hold the merge and point reviewers to the engineer who made the original decision.
Unified AI reviewer view
The pricing page says Haystack aggregates CodeRabbit, Copilot, Greptile, and 10+ AI reviewers into one view, reducing the need to jump between tools.
Merge queue automation
Haystack includes a merge queue that rebases, resolves conflicts, and retries CI automatically.
Context-rich review chat
Reviewers can chat with full coding agent context to trace changes and ask questions in context.
Use Cases
“Triage high-volume PR queues”
Use Haystack to surface the PRs that need review while routine changes keep moving through the pipeline.
“Protect architectural decisions”
Use it when a change might undo a previously agreed implementation choice, so the relevant decision maker is looped in before merge.
“Automate merge housekeeping”
Use the merge queue and automated conflict/CI handling to reduce manual babysitting on straightforward merges.
“Consolidate AI review signals”
Use the unified reviewer view and chat context when a team already relies on several AI review tools and wants them in one place.
“Review agent-generated changes”
Use it to give reviewers context from coding-agent sessions, so they can trace why a change was made before approving it.
