FastF3

A lightweight and highly customizable replacement for Minecraft's F3 debug screen, with draggable HUD widgets, presets, and performance stats.

FastF3 is a lightweight and highly customizable Fabric mod that replaces Minecraft's cluttered F3 debug screen with a cleaner, easier-to-read interface.

By default, FastF3 keeps things simple and shows only the most useful information, such as FPS and coordinates. From the settings menu, you can choose exactly what you want to see and build an F3 screen or permanent HUD that fits the way you play.

Features

  • Clean replacement for the vanilla F3 debug screen
  • Customizable permanent HUD
  • FPS, coordinates, biome, direction, light level, ping, memory, frametime and many more statistics
  • Average FPS and 1% Low FPS
  • Drag-and-drop HUD editor
  • Custom widget positioning, scale, colors, backgrounds, opacity and alignment
  • Combined widgets using variables such as {fps}, {x}, {y}, {z} and {ping}
  • Custom text widgets
  • Conditional widgets that can appear only in specific situations
  • Built-in presets:
    • Minimal
    • Survival
    • PvP
    • Technical
    • Performance
    • SMP
  • Different profiles for individual worlds and servers
  • Import and export HUD layouts
  • Shareable HUD configuration codes
  • Quick switch between Fast F3 and Vanilla F3
  • Vanilla F3 shortcuts such as F3 + B and F3 + G remain usable
  • English and Italian localization

Easy to use

FastF3 is designed to be simple immediately after installation. The default layout only displays the essentials, while advanced options are available for players who want complete control over their debug information.

Open the settings using Right Shift, through the Minecraft pause menu, or through Mod Menu when it is installed.

The default key for temporarily switching between Fast F3 and Vanilla F3 is ,.

Performance

FastF3 is designed to keep its own performance overhead as low as possible. Different statistics use appropriate update intervals instead of unnecessarily recalculating everything every frame.

It is intended to work alongside common Fabric mods such as Sodium, Iris and Lithium whenever possible.

Requirements

  • Fabric Loader
  • Fabric API

Mod Menu is optional.

Privacy

Shared HUD configurations are designed not to include private server or local-world information by default.
