by ufz0

josefclient is a client-side Fabric mod for 1.21.3 that shows FPS, CPS, coordinates and item durability in an overlay.

FabricClient-side onlyAll rights reserved1.21.3

What it does

Once installed, josefclient displays a set of informational overlays on the game screen: the current frames per second, clicks per second, the player's coordinates and the durability of the item held. Pressing F6 opens the mod menu, where each overlay can be toggled on or off. A second group of readouts shows general information about the world the player is in.

The mod is a small side project by ufz0, built as a test bed for learning the Fabric API and improving coding skills. It is intended for single-player and multiplayer clients alike, since it changes nothing on the server side. Its listed goal of a custom modpack and a dedicated client launcher is marked as coming soon, so neither is part of the current release.

josefclient is published only for Fabric, for the single game version 1.21.3, as build v0.9.0-alpha dated 2025-02-20 on the alpha channel. Only the client needs it. The code is not open source and is covered by All rights reserved.
