CAntiXray is a lightweight anti-xray mod for Fabric 1.20.1-1.20.6 and 26.1.x. It works on dedicated servers and in singleplayer worlds, hiding ores until they’re exposed so xray cheats are ineffective without requiring a client mod.

About this Mod

Description

CAntiXray is a lightweight anti-xray mod for Fabric 1.20.1-1.20.6 and 26.1.x. It works on dedicated servers and in client singleplayer worlds, obfuscates vanilla ores (including ancient debris) in chunk data, then reveals real blocks when they're actually exposed. This makes xray cheats ineffective while keeping gameplay natural.

Key Points

Works on dedicated servers and in client singleplayer/integrated worlds.
Players do not need the mod on the client in multiplayer.
Configurable radius and block list.
Supports overworld and nether ores, including ancient debris.
Live chat commands: /cantixray about, /cantixray logs, and /cantixray toggle.

Config

On first run it creates config/cantixray.json. You can edit:

enabled: toggle on/off
revealRadius: how close blocks must be to air/fluid to show
treatFluidsAsExposure: reveal near water/lava
hiddenBlocks: list of blocks to obfuscate

Note: /cantixray toggle updates the config file immediately.

Notes

Lightweight and focused on server performance.
Available for Minecraft 1.20.1-1.20.6 and 26.1.x.

Server lagging with CAntiXray – how to optimize performance?

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