ClientSide Commands
by maDU59_
ClientSide Commands adds a set of client-only chat commands for quality-of-life tasks, settings changes and debugging, and it works without any server-side install.
What it does
Installed on a player's client, the mod registers a collection of non-cheat commands that run inside the game client. They cover everyday conveniences, quick access to options, and debugging aids that developers can use while testing. Because the commands are handled locally, a server does not need to know about them.
The mod also adds an F3 debug screen entry that shows the active keyboard layout, opened with the F3 key. Fabric API is required on Fabric and Quilt. The project is released under the MIT License, and its source code and issue tracker are public. Files target 1.20 – 1.21.11 and are published for Fabric, Forge, NeoForge and Quilt, with the latest Fabric and Quilt builds at 1.0.3 for 1.21.11 and the latest Forge and NeoForge builds at 1.0.1 for 1.20.1.
Key features
Quality-of-life commands
A set of client-side commands handles small everyday tasks that vanilla does not expose directly.
Settings commands
Commands let the player change client options from the chat box without opening the options menu.
Debugging commands
Commands aimed at developers help inspect client state while building or testing content.
Keyboard layout in F3
The F3 debug screen shows the active keyboard layout, so the layout is visible without another tool.

Use cases
Testing a modpack on a single client
A developer can run the debugging commands on a local client to check state while building content, without any server setup.
Who it’s for: Players who want small convenience commands in the client, and mod developers who need debugging helpers while testing. Servers do not need the mod, since it runs on the client alone.
How it compares
PerplexedClientUtils is a Fabric-only, client-side mod for 1.21.4 – 1.21.11, released under the MIT License and open source. CHCP covers Fabric and Forge for 1.20.1 – 1.21.11, is client-side only, and is not open source, as All rights reserved applies. Screencopy and Chat Copy are also client-side and open source, but each targets a different feature set, so compare them by the function needed.
