FabricProxy-Lite is a Fabric mod designed for server-side use only. And it enables Velocity proxies to forward player data to Minecraft servers by handling Velocity packets through Fabric-API. This mod is a lightweight alternative to FabricProxy, focusing exclusively on Velocity support.
The mod requires server installation and doesn't function on the client side. Once installed, it generates a configuration file upon first server start. Users must configure Velocity to use modern player-info-forwarding-mode and set a forwarding secret that matches the secret in FabricProxy-Lite's config file.
Configuration options include hackOnlineMode, which allows connections through a proxy without disabling online-mode and defaults to true. hackEarlySend, when enabled, uses a mixin to send player info earlier in the login process and is required for certain mods like LuckPerms. hackMessageChain helps prevent kicks due to missing or invalid chat packet signatures when players switch servers. disconnectMessage sets the kick message for players not connecting via Velocity, defaulting to 'This server requires you to connect with Velocity.' The secret field is required and must match the Velocity forwarding secret.
FabricProxy-Lite supports Minecraft versions ranging from 1.20.1 up to 26.3, including intermediate 1.21.x releases and pre-release 26.x versions. Here's the thing, it's compatible only with the Fabric mod loader. The mod is licensed under MIT.
This mod is suited for server administrators running Velocity-powered networks who want to integrate player data forwarding with Fabric-based servers while maintaining compatibility with other mods that rely on early packet handling or chat signature validation.
