How real is code review in your repo?

This tool looks at your repo's merged pull requests from the last 5 years (up to 5,000 PRs), quarter by quarter, and checks how real the reviews were — using benchmarks from our study. It only reads review metadata — never your code, diffs, or comment text.

What it checks

Silent approvals
Approvals with no words and no comments — benchmarked against the 66.5% study median.
Zero review
PRs merged with no approval at all. Median company repo: 4%.
Speed-read approvals
Approvals faster than a human can read the diff (300 lines/minute).
Self-merges
Authors merging their own work with nobody else approving.
Reviewer concentration
How much of your review load rests on one person. Study median: 40%.
PR size trend
Median PR size per quarter. The study median jumped from 85 to 124 lines since 2022.
Lines per developer
Merged lines of code per active developer, quarter by quarter.
Lines per reviewer
Approved lines per active reviewer — how the review load changes over time.

Sign in with GitHub, connect the repositories you want checked (read-only — nothing is posted to your PRs), and start the scan. Small repos finish in about a minute; a five-year scan of a busy repo can take 15–20 minutes — we email you the report when it is done, so you don't have to wait around.
