freeCodeCamp
by freeCodeCampfreeCodeCamp.org's open-source codebase and curriculum. Learn math, programming, and computer science for free.
In simple words: codeworld is a free tool, for learning how to code. It is completely free and open source — its code is public on GitHub, where 1,270 people have bookmarked it as worth using.
💡 A real-life example: You learn new words a few cards at a time with a tool like this — a little daily practice that actually stays in memory.

Open-source licenses like this usually allow free use, including commercial use — but always read the actual license file in the repository before relying on it.
