In their own words
Codecov
Codecov provides code coverage reporting and development insights, with tools for test analytics, JavaScript bundle monitoring and pull-request checks. It reports line, branch, project and patch coverage in XML, JSON and TXT formats. Pull-request annotations and coverage gates help teams review changes; Status Checks can block a merge when coverage is underperforming. Historical trends show coverage over time. Test Analytics reports failures and detects flaky tests, while Bundle Analysis flags oversized JavaScript bundles in pull requests and tracks bundle-size changes. The homepage also describes AI features for generating unit tests and reviewing pull requests. Developers can use a command-line interface or VS Code extension for coverage information and visualization. Integrations include GitHub, GitLab, Bitbucket, CI platforms and Slack. Codecov lists a broad range of supported languages, including C#, Go, Python, JavaScript, Rust and Swift. It is available through web, API, extension and self-hosted options. The free Developer plan has upload limits for private repositories; paid plans start at $5/user/mo, and a 14-day trial is available.
