BukkitFabricLoader
BukkitFabricLoader lets Bukkit, Spigot and Paper plugin jars load and run on a Fabric 1.21 server, so plugin code can work alongside Fabric mods.
What it does
Plugins written for the Bukkit, Spigot or Paper APIs are distributed as .jar files. This mod reads those jars on a Fabric server and manages each plugin through its full lifecycle: loading, enabling and disabling. Bukkit events are bridged to the Fabric side, and plugin commands, scheduled tasks and the permission system are supported as well.
Basic multi-world support is included, and error messages are written in Chinese with detailed output to help diagnose failed loads. The mod is server-side only, so players join without installing anything. It requires Fabric API, which must also be present on the server.
Files are published for Fabric alone, across 12 release versions, 1.21 – 1.21.11. The latest file is 1.0.3 for 1.21.11, released 2026-02-15, and the first file appeared on 2026-02-12. The code is released under the MIT License, and the project is not open source.
