Plugin OtterLib

OtterLib, the flexible Minecraft library for plugins and mods

OtterLib is a lightweight library for Minecraft Java that unifies tools for both mods and plugins, supporting Fabric, Quilt, Spigot, Paper and related platforms. It focuses on clean utilities like an advanced chat text builder, server side localization and robust config file handling, so developers can spend less time reinventing core features and more time polishing gameplay on any Minecraft server.

The library powers both client and server environments, with a simple API for managing files and language packs across multiple Minecraft versions, including the 1.20 and 1.21 series. On BoxToPlay, our team uses OtterLib to help creators deliver stable, configurable experiences on every hosted Minecraft server.
