NullTrace

NullTrace is a client-side Fabric mod that gives you more control over what your Minecraft client sends to servers.

It helps hide common signs of a modded client, limits mod-channel exposure, protects against translation-key and keybind checks, and reduces tracking through server resource packs.

Features

• Spoof the client brand as vanilla
• Filter mod and client-identification channels
• Block ViaFabricPlus and ViaVersion identity details
• Protect against translation-key and keybind checks
• Normalize client information sent to servers
• Isolate resource-pack caches between accounts
• Block resource-pack requests to local and private addresses
• Remove username and UUID headers from resource-pack downloads
• Filter known packs and mod shader overrides
• Control how server resource packs are handled
• Block server cookies and unwanted server transfers
• Disable telemetry
• Configure chat signing
• Manage multiple accounts
• View alerts and connection diagnostics

Supported Minecraft versions

• 1.21.11
• 26.1
• 26.2
• 26.3

Compatibility

Some protections can interfere with mods or servers that rely on custom networking channels, server cookies, protocol information, or resource packs. These options can be adjusted from the NullTrace configuration screen.

NullTrace does not make a client completely undetectable. Protocol translation, gameplay behavior, connection information, and other factors may still reveal differences to a server.

NullTrace is intended as a privacy tool and is not an anti-cheat bypass.
