In simple words: server is a tool you run on your own computer or server, then open in your browser, for working together on documents and projects. It is completely free and open source — its code is public on GitHub, where 37,389 people have bookmarked it as worth using.
💡 A real-life example: A school runs its own chat with a tool like this, so teachers and students talk in one private place instead of scattered WhatsApp groups.
RepoEasy wrote this simple explanation from the project's public data — its category, topics and description — so a beginner can understand it before downloading anything. For exact technical details, the project's own README (linked below) is the final word.

The source code is released under the AGPL-3.0 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.
