Speedrun F3

by Tamo55+Slayt7

Speedrun F3 replaces the vanilla F3 debug overlay with a slim minimalist screen for speedrunners, shown only when the player opens it.

What it does

The mod strips the vanilla F3 debug screen down to the data a run depends on. Performance statistics and technical clutter are removed, leaving a clean HUD with a slim shadowed font on a transparent background, so the text stays out of the way during intense runs. Entity counts, precise facing angles, coordinates, and biome and chunk boundaries are kept on screen.

Entity counts include a rendered total, which helps track hidden Bastions and Nether Fortresses. Facing angles are shown with exact values, which suits locating a stronghold from several eye throws. Structure navigation uses the coordinates and chunk boundaries to locate structures without distracting block data.

Speedrun F3 is a client-side Fabric mod, so only the player needs it and servers run without it. It is released under the MIT License and is open source. Files cover game versions 1.21 – 1.21.11, with v1.5.0 for 1.21.11 as the latest file, and the source code and issue tracker are public.

Key features

  1. Minimalist clean interface

    A slim shadowed font on a transparent background keeps the debug text readable without covering the game view.

  2. Entity radar and E-count

    The screen tracks the entity count and rendered total, including hidden Bastions and Nether Fortresses.

  3. Precise facing angles

    Exact facing direction angles are displayed for stronghold triangulation and Eye of Ender tracking.

  4. Structure navigation

    Coordinates and biome and chunk boundaries help players locate structures without irrelevant block data.
