Fumi-sitmc is a server-side message forwarding tool built on a NATS server, relaying chat between different messaging platforms.
What it does
The mod sets up a forwarding channel that passes messages between separate messaging platforms. Messages from several sources reach one central NATS server, which sends them out in a unified format that each client parses.
Servers run it alone, and players join without installing anything. It is published for Fabric and NeoForge for 26.3, with builds covering 1.20.5 – 26.3 and open source status not claimed; all rights are reserved.
Key features

A NATS server acts as the shared point that collects messages from all connected platforms.
