NoF3 is a simple client-side mod for Minecraft 1.20.1 (Forge) that completely disables the F3 debug screen.
The mod is made for players on RP/survival servers who don’t want others to use the “cheaty” features of F3: coordinates, FPS, biome info, chunk data, etc.
After installing NoF3:
Pressing F3 no longer opens the debug screen.
All debug information stays disabled.
The mod works client-side only and does not need to be installed on the server (and the server cannot force players to use or remove it).
This is a convenient solution for those who:
Run RP servers where players are not allowed to see their coordinates.
Build hardcore modpacks where the player should navigate using the world itself.
Want to remove unnecessary debug information and keep the interface clean and immersive.
