About Codecov
Codecov is a hosted service that reports on code coverage, flags failing and flaky tests, and comments on pull requests. It connects to the continuous integration tools and code hosts that a team already uses.
What it does
Codecov takes coverage data from test runs and shows it in each pull request, so you can see whether new code is tested. It highlights flaky and failing tests and points to the lines and tests involved. It can also track JavaScript bundle size and enforce limits with status checks. The product page describes AI features for generating unit tests and reviewing pull requests.
Key features
- Coverage comments on pull requests
- Flaky and failing test reports

- Status checks to block risky merges
- Works with many languages and CI tools
Who it's for
Codecov suits development teams that want coverage visible during code review, and teams with unstable test suites. It fits teams whose pipelines use a mix of CI tools and languages.
Pricing and good to know
The site invites visitors to try the service for free and to request a demo. It runs as a hosted service that connects to GitHub, GitLab and other code hosts. Coverage numbers are only as useful as the tests behind them, so pair the service with tests you trust.
