developer-roadmap
360k stars, personal-use only
What it is
Interactive career roadmaps and guides for developers — frontend, backend, DevOps, AI, and dozens more — powering roadmap.sh, plus the roadmap content itself.
Why it's interesting
One of GitHub's most-starred repositories ever, and a common example of 'famous but not open source.' Its custom license permits personal use only: you can't republish the content in blogs or newsletters without consent, and commercial reuse is prohibited. (And despite appearances it isn't a fork — the author renamed his account from kamranahmedse to nilbuild.)
Use cases
- Learning paths and career planning
- A curriculum reference
Who it's for
Developers at all levels; educators
Setup
Trivial. Just read it at roadmap.sh; Node and Astro to run the site locally
Limitations & cautions
The content, not just the site code, is under a restrictive license — treat it as a resource to link to, not to reuse.
Editorial takeaway
A reminder that a star count is a popularity metric, not a license. Wonderful to learn from; not yours to redistribute.
