In simple words: server-survival is a free tool, for learning through games. It is completely free and open source — its code is public on GitHub, where 6,473 people have bookmarked it as worth using.
💡 A real-life example: A teacher puts lessons in a platform like this, and students watch, practise and get tested from home.

The source code is released under the MIT license. 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. Note: the code being free does not mean hosted services, APIs or infrastructure around it are free.
