2020 State of Open Source Code Coverage

Since our founding six years ago, it has been a core tenet at Codecov to provide the best code coverage analytics to developers and organizations.

To give our developers a better grasp of the code coverage landscape, we have compiled our most significant learnings from 2020 in our new annual State of Open Source Code Coverage. Here is what we found.

General Codecov Usage

Codecov is dedicated to being free forever for open-source projects. We saw an incredible level of usage on our platform to analyze code coverage on your repositories.

Code Coverage Usage by Language

Codecov continues to be language agnostic, ensuring that developers across the board can get code coverage data. We present metrics around language usage by popularity and by the average code coverage for projects of a language.

Codecov CI Usage

Codecov continues to work with all CIs in the developer ecosystem. In 2020, however, we saw a meteoric rise in usage of GitHub Actions.

Featured Open Source Repositories

Our open-source community continues to be a cornerstone of our product development. We take a step back to showcase and congratulate some of our more popular repositories and their efforts to reach high code coverage.

Codecov Benefits

Our goal is to help developers merge their code with confidence. We continually work to see how adding code coverage can benefit projects.
