# NetworkCore Docs

NetworkCore is the foundational plugin every other KweebecNet plugin depends on. It owns metrics, cross-server messaging, and the server-discovery layer.

If you're building a plugin that needs to talk to other servers, record stats, or know who else is online, you depend on this.
