PatPatFix
by F1xASASASASA
PatPat Fix lets pats sync between players on servers that run neither the PatPat mod nor the PatPat plugin, using an external relay server.
What it does
Normally PatPat syncs pats only between players whose server runs the PatPat mod or plugin. PatPat Fix adds a fourth route that works independently of the server: each client hands its pat to an outside relay, which passes it along to the other players on the same server who have the addon installed. Players join a room automatically, based on the Minecraft server address, so everyone on the same server ends up in the same room.
Clients play the animation and sound when a pat arrives, just as they would for a pat received through the normal route. The addon intercepts the pat event and sends it over a WebSocket connection to the relay. The server itself needs no admin rights, plugins or mods for this to work. Groups can host their own relay on a small VPS.
The mod is installed on the client only and targets Fabric. Builds exist for 1.20 – 26.2 across 20 release versions, and the latest file is 1.1 for 26.2. It is released under the MIT License and is not open source.

External relay forwarding
A WebSocket relay forwards each pat event to the other players on the same server who have the addon installed.
