Shard is a Minecraft anti-cheat that using AI to flags aimbot, killaura, aim-assist and similar aim-based cheats using a machine-learning model.

What it catches
Aimbot, killaura, aim-assist and similar aim-based combat cheats.

Cloud-based detection
Detection runs on Shard's servers, not on your game server. The plugin collects the required data and forwards it to the Shard cloud, where the model performs the analysis. The performance impact on your server stays minimal, even at high player counts.

Setup
Create a free account at shard.ac and install the plugin on your server. Run /shard connect in-game or from the console and approve the request in your dashboard to link the server.

Pricing
Shard has a free tier suitable for smaller servers. Bigger servers need a paid plan for the extra traffic. The paid plan is credit-based and priced on the traffic you send, so the cost tracks real usage.

Open source
The plugin is licensed under GPLv3, with the full source available on GitHub. You can review it, build it yourself, and verify exactly what data leaves your server.

Requirements
  • A free Shard account
  • Outbound internet access from your server to shard.ac, since detection is cloud-based
