keranantixray

KeranAntiXray is a high-performance Anti-Xray and Anti-Freecam plugin designed specifically for Paper, Folia, and Canvas 1.21+. It provides advanced Nether Roof protection to prevent players from using Freecam to inspect areas above or below the bedrock layer.

Core Features

World-Based Anti-Xray

• Separate configuration for:
  • Overworld
  • Nether
• Hide blocks below a configurable Y-level
• Optimized for high-performance servers

Nether Roof Protection (Anti-Freecam)
When a player is below the bedrock roof:

• All blocks above the configured roof Y-level are sent as air
• Freecam cannot see bases or builds on the Nether roof when the player is below the bedrock roof
• Full chunk data is restored automatically
• No interference with legitimate roof gameplay

Compatibility

• Paper 1.21+
• Folia
• Canvas
• Java 21+
• No ProtocolLib required
• No external AntiCheat required
