The repository reports a Apache-2.0 license. Setup difficulty and device support still need to be checked upstream.
Evidence & freshness
What we know, and how recently we checked
This record comes from the wider automated directory. It has not yet passed the stronger catalog verification checks.
- Source
- Automated project sync
- Checked
- Snapshot evidence level
- Limited confidence
- Maintenance signal
- Healthy74/100
Generally healthy automated signals, with some areas worth checking in the breakdown.
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.
