Codecov is a code coverage reporting tool that integrates with CI pipelines, collects coverage reports from multiple languages, and provides visualizations, pull-request comments, and coverage enforcement.

Codecov’s UI and coverage upload endpoints (codecov.io) are intermittently reachable from China. Coverage badges and pull-request annotations may fail to load. Teams often self-host coverage tools like SonarQube or use local artifacts to enforce coverage policies.

The information regarding service availability in China is provided for general reference purposes only. Due to the dynamic nature of network conditions and regulatory environments, the actual accessibility of these services may vary over time and by location. Users are advised to verify the current status independently.
