Experimental & Unusual

developer-roadmap

360k stars, personal-use only

Not open sourceContent, not software

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.
