How Coveralls Works With Your CI Pipeline

Coveralls does not run tests itself; it receives coverage reports generated by a project's existing test runner and CI service. A language-specific client library or generic coverage file (such as lcov.info or a Cobertura XML report) is uploaded to Coveralls as part of a CI job, typically the same job that already runs the test suite.

Once uploaded, Coveralls stores the report, compares it against the coverage history for that repository, and updates pull request checks and comments so reviewers can see the coverage delta caused by a specific change before approving a merge.

Coveralls Pricing Structure

Coveralls pricing is built around the number of private repositories a plan includes, rather than the number of users, since all cloud plans include unlimited users. This makes Coveralls comparatively predictable for larger teams working across many private repos under a single organization.

Add-ons for premium support and additional upload volume can be layered on top of any Cloud plan, while Enterprise options move to per-user pricing for organizations that need private infrastructure or fully on-premises deployment.

Coveralls Compared to Similar Tools

Coveralls is most often compared with Codecov, both of which focus specifically on coverage tracking and pull request reporting rather than broader static analysis. Coveralls differentiates itself with unlimited-user pricing on paid plans and a long-standing free tier for open source projects.

Teams that also want linting, security scanning, or code quality metrics alongside coverage sometimes pair Coveralls with a separate static analysis tool, since Coveralls intentionally stays focused on coverage rather than expanding into a full code quality suite.

Pros & Cons

Pros

  • Coverage badges and PR diffs make results easy to surface publicly and in reviews

Cons

  • Focused narrowly on coverage, without the broader static analysis or code quality features some competitors bundle in
  • Private repository pricing is tied to repo count per organization, which can require plan upgrades as a team grows
  • Enterprise on-premises and enterprise cloud tiers require a 40-seat minimum on the cloud option
  • Company size and support resources are smaller than larger competitors like Codecov
  • Interface and reporting depth are simpler than some full-featured code quality platforms
