🌉 NexusBridge

Discord ↔ Minecraft Bridge — NeoForge 1.21.1

The most complete Discord ↔ Minecraft integration for NeoForge 1.21.1

✨ Features

🔗 Bidirectional Chat Sync

Messages sent in-game appear on Discord, and Discord messages appear in Minecraft — instantly, with full username and prefix formatting.

🛡️ Full Sanctions Management

Bans, temporary bans, and mutes are synchronized across both platforms in real time. Unban and unmute operations are automatically propagated.

✅ Discord Verification System

Link your players' Minecraft accounts to their Discord identities with a secure 6-digit code system. Codes expire after 5 minutes. Unverified players can optionally be kicked.

🔐 LuckPerms Integration

Full support for LuckPerms permission groups — control who can ban, mute, and manage players directly from Discord or in-game.

💾 Database Persistence (MariaDB / MySQL)

All data (players, bans, mutes, chat logs, verification codes) is stored in a MariaDB/MySQL database via a HikariCP connection pool for maximum reliability and performance.

🌐 Full i18n Support

NexusBridge ships with French and English translations out of the box. Adding new languages is as simple as dropping a new file.
