Nickname Detector

by SmushyTaco

Nickname Detector flags a player whose in-game display name differs from their real account name, so server staff can notice nicknames.

FabricClient-side onlyApache License 2.0Open source1.20.1 – 26.2

What it does

The mod compares the username a player connects with against the name shown in chat and on screen, and reports a mismatch. The author notes that real usernames are not checked in the way that catches nicknames, and that the mod catches most of them. The mod runs on the client alone, so only the player's own game needs it, and it targets Fabric for 1.20.1 – 26.2 across 18 release versions, under the Apache License 2.0 as open source. It requires Fabric API and Fabric Language Kotlin.

Key features

  1. Nickname detection

    Flags a display name that differs from the account username, catching most nicknames rather than every case.

  2. Issue reporting

    Problems are reported through the Issues tab of the project, following the issue template the author provides.

  3. Port permission

    The author has no plans for a port to another loader and allows others to port the mod to other platforms.
