What Codecov is
Codecov provides code coverage reporting and insights intended to help teams improve code quality during development. It reports line, branch, project, and patch coverage, with report formats including XML, JSON, and TXT. Pull-request annotations and coverage gates support review, and Status Checks can block underperforming pull requests from merging. Historical trends show coverage over time. Test Analytics reports test failures and detects flaky tests, while Bundle Analysis alerts teams to oversized JavaScript bundles in pull requests and tracks size changes. The homepage 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 supports languages including C#, Go, Python, JavaScript, Rust, Java, and Swift. It is offered as a web service, API, extension, or self-hosted option. Plans include a free Developer tier, Team at $5 per user/month, Pro at $12 per user/month, and custom Enterprise pricing. A 14-day trial is listed.
