A new way to measure code coverage

What if we could quantify, and then improve, person-to-person code reviews?

At AutoDev, we believe we help you and your team write better code by understanding code coverage, churn and engagement. We start by looking at “engaged” reviews: how much code is part of a review with comments before merge? We’ve analyzed popular repos to build the first AutoDev Analytics benchmark report. Check it out below or get analytics for your own repo.

Benchmark Repositories

We analyzed hundreds of millions of lines of code from the most popular open source repositories. Based on what we learned, we built benchmark metrics for our analytics. Almost all of our metrics include their benchmark averages for comparison. Take a look at some of the most popular repositories below, or use the search box above.
