F3 Lite
F3 Lite is a Fabric HUD overlay that shows the most useful debug values in a compact panel, so the full F3 screen does not have to stay open.
What it does
A single key toggles the overlay, and the key is bound to a default that can be changed. The panel lists coordinates with chunk information, the biome name, facing direction with yaw and pitch, the surface Y value at the highest block under the player, and an FPS counter. Coordinates can be converted between the Nether and the Overworld, and the count of hostile entities nearby is shown as well.
For players who want the full debug data, a separate screen presents the complete F3 menu. The overlay is minimal and set up for low performance cost, and its options can be adjusted in the configuration. The project draws on the speedrunning HUD style and is aimed at survival play, where quick reference values matter more than the whole debug output.
F3 Lite runs on the client only, so players install it and servers do not need it. It is released under the MIT License and is open source, with source code and an issue tracker published. Files target 1.21.8 and 1.21.9, and the latest build is 1.1.0+MC_1.21.9 for 1.21.9, released on 2025-10-03.
Key features
Compact debug overlay

Position and direction readout
Coordinates, chunk position, yaw, pitch and a compass facing shown as N, NE, E and so on are listed together.
Nether and Overworld conversion
Coordinates are converted between the two dimensions, which helps when planning travel through portals.
Nearby hostile count
The panel reports how many hostile entities are close to the player, along with the surface height and FPS.
