Which Ruby projects are most actively maintained?

What licence are Ruby projects usually under?

52 of the 58 carry an explicit open-source licence across 8 distinct licences, and the licence is shown on every card. Permissive licences (MIT, Apache-2.0) are the safest default for commercial use; check the copyleft ones individually.

Should I use Ruby or Python for my project?
