Debrand
by LoganDark
Debrand changes the client brand string that Minecraft reports to servers, so a Fabric client can appear as an unmodded game on a server.
What it does
The mod alters the brand a client sends during the connection, which matters for servers that check the brand before allowing a join or that rely on it for detection. Debrand lets players run most quality-of-life setups on Fabric without the server learning that a mod is present through the brand alone.
Debrand is aimed at players who need a modified client to look vanilla to a server, and at developers who want to study how servers probe clients. It does not hide mods from every check: a server can still inspect behavior, translation keys, custom packets or registry data, which the author notes describe as ways detection can still succeed.
The mod is licensed under the MIT License and is open source, with the source code and issue tracker public. It is published for Fabric only, across 47 release versions 1.14 – 26.2, and either side can run it, and neither needs it. Snapshot builds are published as well.
Key features
Brand replacement
Replaces the client brand reported during login, so the connection looks like a standard Minecraft client.
Protection against passive checks
Covers the default brand check that many servers use to decide whether a client is unmodded.
Behavior that stays visible
Actions taken by a modified client remain visible to observers, so cursory checks do not notice a change in behavior.
Known limits of detection
Server probes such as translation key lookups, custom packets and Fabric API registry sync can still reveal a modified client.
Screen-sharing safety
Installed mods do not change anything that appears on screen, so a viewer cannot tell the game is modified from the picture.

Use cases
Who it’s for: Players who use modified clients on servers that check the brand, and developers who study how servers detect mods. Servers that run anticheat should expect that detection through behavior or packets can still succeed.

What the author says
This is most useful for QoL setups, where there is no need to change the brand of the game. This mod is most useful against passive detections (since by default, the Minecraft client volunteers its brand to the server) and cursory glances (that don't notice modified behavior).
