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.
Coveralls
Coveralls analyzes software test coverage, showing teams which code is not covered by tests. Its dashboard presents project coverage percentages and their changes over time, while repository views drill down from a project to sub-projects, files, and individual lines. Build history tracks coverage across branches, including pull requests. Coveralls can add summarized coverage results to pull requests and send status updates that apply coverage criteria to merge decisions. Notifications can go to Slack or webhooks. It supports line and branch coverage, with report formats including LCOV, SimpleCov, Cobertura, JaCoCo, and Clover XML. Coveralls says it works with any CI service and lists more than 30 community-created integrations, a GitHub Action, and a CircleCI Orb. An API can add repositories programmatically and return recent build statistics. Open-source and public repositories are free. The Starter plan is $10 a month for one private repository and includes a 30-day trial. A self-hosted enterprise installation can operate within existing security controls without outbound network access.
