PR Pulse: GitHub PR Age & Complexity Extension
Free Chrome extension showing PR age badges and complexity scores on GitHub. Color-coded indicators help spot stale PRs instantly. Zero data collection, fully customizable.
Spot Stale PRs Instantly on GitHub
PR Pulse adds color-coded age badges and complexity scores directly to GitHub pull request pages. See which PRs need attention at a glance.
Add to Chrome - It's FreeOur Take
Long-lived PRs are technical debt hiding in plain sight.
Every day a PR sits open, it accumulates merge conflicts, drifts from the codebase, and loses context in the author's mind. Research shows PRs open longer than 3 days have significantly higher defect rates and lower review quality. Making age visible turns it into something teams can actually act on.
"PRs over 1,000 lines receive 18x less scrutiny per line than small PRs."

Features
PR Age Badges
Color-coded badges show PR age at a glance. Green for fresh (<24h), yellow for getting stale (1-3d), red for needs attention (>3d).
Complexity Scores
See PR complexity based on files changed and lines of code. Low, Medium, High, or Critical ratings help prioritize reviews.
Fully Customizable
Set your own age thresholds, configure complexity scoring, and toggle badges on/off for different page types.
What The Age Colors Mean
These thresholds are fully customizable in the extension settings.
Complexity Score Breakdown
| Level | Lines Changed | Review Approach |
|---|---|---|
| Low | <100 lines | Quick review, low risk |
| Medium | 100-400 lines | Moderate attention needed |
| High | 400-1000 lines | Thorough review, consider pairing |
| Critical | >1000 lines | Consider splitting the PR |

Why PR Age Matters
Research consistently shows that long-lived pull requests are correlated with lower code quality and team productivity issues:
- Higher defect rates: PRs open longer than 3 days have significantly more bugs introduced, partly because authors lose context over time.
- Lower review quality: Reviewers tend to rubber-stamp old PRs to clear their queue, leading to less thorough feedback.
- Increased merge conflicts: The longer a PR sits, the more the target branch changes, creating integration headaches.
- Developer frustration: Old PRs blocking feature work create context-switching costs and reduce team velocity.
