PRs Without Review %
Pull Request Lifecycle
%
Shows the percentage of merged pull requests that had no review or approval.
💡 Like your quality assurance pass rate, the higher this percentage, the more your team is shipping on trust rather than verification.
What It Measures
Shows the percentage of merged pull requests that had no review or approval.
Why It Matters
Tracking review compliance rate
Identifying if too many PRs bypass the review process
How It's Calculated
Divides merged PRs without review by total merged PRs and multiplies by 100.
100 × COUNT(prs WHERE merged AND review_count = 0) ÷ COUNT(prs WHERE merged)Concrete Example
If 4 of your 40 merged PRs had no review, your unreviewed merge rate is 10%, meaning 1 in 10 changes shipped without a second set of eyes.
