PAPIProxyBridge
by WiIIiam278
Server plugins that format text with PlaceholderAPI placeholders can reach players across a proxy through PAPIProxyBridge, a Fabric library that bridges the call between servers.
What it does
PAPIProxyBridge is a library that lets proxy plugins resolve PlaceholderAPI placeholders on the backend. Both backend proxy servers need the plugin installed, and the proxy side runs on Velocity, BungeeCord or Waterfall. The mod is published for Fabric, and the same bridge is also offered as a plugin for Paper, Spigot, Folia, Velocity, BungeeCord and Waterfall.
Resolved requests are cached for 30 seconds, so repeated lookups do not flood the server's network channels with traffic. The cache duration can be changed through PlaceholderAPI's cache expiry setting. Because the bridge uses PlaceholderAPI, the Text Placeholder API mod is an optional dependency, and the backend still needs PlaceholderAPI installed on Spigot or Fabric. Builds cover 1.16.5 – 1.21.8, and the latest Fabric file is 1.8.4-1959e64 for 1.21.8.
PAPIProxyBridge is open source under the Apache License 2.0, with public source code and an issue tracker. It was first published on 2023-03-06 and last updated on 2026-09-02.
Key features
Proxy-to-backend placeholder formatting
Proxy plugins can format text with PlaceholderAPI placeholders on a backend server through a single call.
Asynchronous formatting methods
Methods return a CompletableFuture, so calls do not block threads on proxy networks that carry many players.
Component output
A method accepts a string with placeholders and returns an adventure component with the formatted text, useful for chat events.
Cache control
Resolved requests are cached for 30 seconds by default, and the expiry time is adjustable for each server.
