A modern replacement for Minecraft's debug overlay. Fully customizable, draggable, and profile-based — all without replacing the vanilla F3 data.
- Mirrors all vanilla F3 debug lines (left and right columns) with a clean, styled overlay.
- Every module is draggable — open the edit screen with F8 and place things where you want.
- Right-click any module to customize text color, background color, opacity, scale, and text shadow.
- Profiles — save and switch between different layouts instantly.
- Snap-to-grid — hold Shift while dragging for pixel-perfect alignment.
- Copy & paste styles across modules or apply a style to all modules at once.
- Full developer API for adding custom modules from other mods.

Modern F3 stores its config per-profile. Profiles are saved in the game directory under .minecraft/config/modern_f3/. You can distribute preset profiles with your modpack by including these files.
See developer.md for the full API guide on adding custom overlay modules from your own mod.
