A 90-second PR shouldn't take 2 hours to review

90 seconds
to generate a 500-line AI pull request
2 hours
for a maintainer to review it

“AI gives people false confidence... they used AI instead of reading any of the existing code.”

— SymPy maintainer, Feb 2026

“AI slop PRs are becoming increasingly draining and demoralizing.”

— Godot maintainer

Thousands of maintainers are closing projects or disabling contributions entirely. There's a better option.

Smart PR Filtering. Zero Manual Review.

PR Guardian runs automated quality checks on every pull request the moment it's opened and scores it 0–100. Free users get the full scoring engine and dashboard. Pro users add the policy layer: set a threshold, and we handle the rest automatically.

Step 1

PR Opened

A pull request is opened. PR Guardian triggers instantly via GitHub webhook.

Step 2

Quality Scored

Five signals checked: commit messages, PR description, test results, code style, contributor history. Score calculated 0–100.

Step 3 · Pro

Policy Runs

Set a threshold in .github/pr-guardian.yml. Below it: auto-closed with a comment. Above it: labelled and surfaced in your dashboard.
