this is what IRC ... does. The xmpp standard and ecosystem of clients/servers has also provided this for a decade plus. If something 'modern' is required, Matrix protocol and its ecosystem is a contender. Also look into the world of ActivityPub federated applications, which cover everything from replacing Twitter to blogging. My personal setup is to use bitlbee or libpurple to connect to every major chat network that exists today, bridged to my irc client via znc. This provides a consistent presence, status, and ui across desktop/mobile, push notifications, filtering, and behavior under my control, all with chat client that doesn't take up 1GB+ of memory with phone-home telemetry and useless emoji
