How to Evaluate Open-Source Project Health
A checklist for judging whether a project is alive, maintained, and safe to depend on — beyond star count.
Activity over popularity
The single most predictive health signal is recent activity. A commit in the last week beats 50,000 stars from five years ago. Check the last push date, the release cadence, and whether issues receive responses from maintainers — not just from other users.
The issue-to-stars ratio
A project with a manageable open-issue count relative to its size is being tended to; one with thousands of unanswered issues is either overwhelmed or abandoned. Normalize by stars to compare fairly: a healthy ratio sits well below the popularity baseline.
License and governance
A clear, permissive license (MIT, Apache-2.0) removes legal friction. Beyond license, look at whether the project has a public governance model or depends on a single overloaded maintainer — bus factor matters for long-term dependencies.
Putting it together
No single signal is enough. DiGitHub combines activity, health (issue ratio + license), match, and popularity into one score precisely because health is multi-dimensional. Use the score as a first filter, then verify the governance and maintainer responsiveness yourself.
