Lighthouse CI vs JaCoCo: open-source CI and reporting tools compared

Metrics as of , from the GitHub or GitLab API of each repository. Refreshed monthly.

Summary

Lighthouse CI: Tool suite that runs, stores and asserts against Lighthouse results in CI, with a server and dashboard.

JaCoCo: Code coverage library for Java with Maven, Ant and command line integrations.

Both are listed under CI and reporting. The table gives repository metrics from the GitHub API with their fetch date, then the documented facts used for every comparison in this category, each linked to the README or docs page it comes from. A cell reads "not documented" when the fact was not found in the project's documentation; that does not mean the feature is absent.
