About this Mod
📜 Rapid Whitelist
A high-performance, hot-reloadable whitelist system for modern Fabric servers.
Rapid Whitelist replaces the vanilla Minecraft whitelist entirely, offering asynchronous I/O, hot-reloading, and advanced rate limiting. It is designed for servers that need a robust access control system without the performance hit of the main thread.
🚀 Why Use This Mod?
- ⚡ Zero Lag: All whitelist operations (add/remove/check) use async I/O to keep your server TPS high.
- 🔥 Hot-Reloadable: Edit
whitelist.jsonmanually or via command, and changes apply instantly without restarting. - 🛡️ Rate Limiting: Built-in protection against command spam for adding/removing players and reloading.
- 🔌 Developer API: Includes a
CustomWhitelistAPIfor easy integration with other mods or plugins. - 🚫 Complete Replacement: Fully bypasses the vanilla whitelist logic for total control.
✨ Features

- Async Storage: Player data is stored in
config/customwhitelist/whitelist.jsonand loaded asynchronously. - UUID & Name Support: Whitelists by GameProfile (UUID + Name) for security.
- Instant Updates: Commands update the cache immediately; manual file edits are detected via file watcher.
⚙️ Management & Control
- Full Command Suite:
/rapidwhitelist add,remove,list,enable,disable,reload. - Configurable Messages: Customize kick messages and feedback text in
config.json. - Permission Levels: Restrict commands to specific OP levels (default: Level 3).
🛡️ Protection
