espressif/arduino-esp32 →
Healthy across the board
copyleft license (LGPL-2.1) — review compatibility
Has a license, tests, and CI — clean foundation to fork and modify.
Documented and popular — useful reference codebase to read through.
No critical CVEs, sane security posture — runnable as-is.
- ⚠LGPL-2.1 is copyleft — check downstream compatibility
- ✓Last commit 1d ago
- ✓32+ active contributors
- ✓Distributed ownership (top contributor 36% of recent commits)
- ✓LGPL-2.1 licensed
- ✓CI configured
- ✓Tests present
What would improve this?
- →Use as dependency Concerns → Mixed if: relicense under MIT/Apache-2.0 (rare for established libs)
Computed from maintenance signals — commit recency, contributor breadth, bus factor, license, CI, tests
