roadmap.sh

roadmap.sh is an open-source project that maps learning paths for technical roles like frontend developer, backend engineer, and DevOps specialist. It's one of GitHub's most-starred repositories, built by thousands of community contributions. The platform pairs these visual roadmaps with an AI tutor that answers questions as you progress through each skill area.

It works best for self-taught developers who want a concrete skill sequence without enrolling in formal courses. The visual format makes it easy to see where you are and what comes next, which matters when you're jumping between topics or switching specializations. The free price point and community nature mean the roadmaps evolve with what the industry actually needs.
