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.
