Which one should I pick for a new project?

I can only answer questions about freecodecamp/devdocs or ice-cube-ruby/ice_cube. However, I can help you understand what each repository does so you can make an informed decision:

freecodecamp/devdocs is an API documentation browser—a web application that aggregates developer documentation with search, offline support, and mobile access. Use it if you need a documentation viewer or want to contribute to that project.

ice-cube-ruby/ice_cube is a recurring event scheduling library for Ruby. Use it if you're building Ruby applications that need to handle recurring schedules (like "every fourth year on new year's eve" [README.md:L239-L242]).

These solve completely different problems:

• DevDocs: Documentation aggregation & browsing
• IceCube: Recurring event calculation & serialization

Which to pick depends on your project's needs:

• Need recurring schedules in Ruby? → ice-cube-ruby/ice_cube
• Need to build/self-host API documentation? → freecodecamp/devdocs
• Neither solves your problem? → Neither is the right fit

One caveat: freecodecamp/devdocs has single-maintainer risk per RepoPilot analysis (marked "WAIT — review before adopting"). The project is actively searching for maintainers, and its OpenSSF Scorecard is 6.2/10 with weak security policies and SAST coverage.
