About this Mod
🔒 KeybindingLocker – Server-Controlled Keybind Locking for Fabric
KeybindingLocker is a lightweight Fabric mod designed for server administrators and event organizers who need to remotely lock specific keybind actions on connected clients.
It enables fine-grained control over player inputs by disabling configurable keybinds during events or gameplay scenarios, enhancing server-side control without client-side mod dependency.
✨ Key Features
- ⛔ Server-Side Keybind Locking
Block specific keybind actions like chat (
key.chat), inventory, or other controls based on server configuration.
- 🔄 Real-Time Sync
When activated via server commands, all connected clients receive updates and have the matching keys locked immediately.
- 🔧 Simple Configuration
Define which keybind actions are locked through an easy-to-edit config file.
- 🎮 Enhances Custom Gameplay & Events
Ideal for roleplay servers, minigames, or events where player controls must be limited temporarily.

KeybindingLocker server crashes on startup – what to do?

Server lagging with KeybindingLocker – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if KeybindingLocker consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
