Strong automated signals across recent activity, community, and project upkeep.

The health score is an automated maintenance signal, not a security audit or a guarantee that the tool fits your needs.

How verification and health scoring work

Catalog-verified records use a timestamped GitHub snapshot that passed source and completeness checks. Basic listings come from the wider automated sync and have not yet passed that stronger verification path.

Health combines recent activity, commit frequency, issue handling, contributor depth, release cadence, documentation, and community signals. Missing evidence lowers how much confidence you should place in the number.
