F3Commands
by DraxonV1
F3Commands replaces the F3 debug screen's key combinations with slash commands that show the same debug information in chat.
What it does
Players type a command instead of pressing F3 combinations, so performance readings, world position, biome, dimension and other debug details can be read without memorizing hotkeys. The commands cover more than 70 client-side actions, grouped into performance tracking, world information, debug tools and graphics or resource controls.
The mod is client-side only, so players join servers without installing it and servers need nothing. Its output is color-coded and formatted for readability, and a built-in help system lists the commands by category. Settings can be changed in-game, and integration with Mod Menu is available as an option. It requires Fabric API and is open source under the MIT License. Files are published for Fabric only, across game versions 1.21.6 – 1.21.8, with v1.1.0-1.21.8 as the latest file for 1.21.8.
