Even Better Developer Tools

A mod for Minecraft mod developers that adds developer-focused tooling directly inside the game — no external IDE or console required.

What's new in v1.1

Performance HUD

Toggle a compact always-on overlay showing FPS, frame time, heap memory usage (used / max, with % fill), GC collection count and total pause time, and server ping. Color-coded green / yellow / red at a glance. Press the bound key (unbound by default, set in Controls) to toggle it on or off.

Full feature list

In-Game Log Viewer

View the full game log without alt-tabbing. Filter by level (DEBUG / INFO / WARN / ERROR) and text, with auto-scroll, color-coded severity, and a timestamp on every line.

Registry Browser

Instantly look up any registered identifier — Blocks, Items, Entity Types, Sound Events, and Particle Types. Click any entry to copy its namespaced ID to the clipboard.

Config Hot-Reload

Watches your entire config directory. When any config file changes on disk, the game fires a ConfigReloadEvent your mod can subscribe to and shows a toast notification — no restart required.

Mixin Inspector

Lists every loaded Mixin configuration and all the classes it injects into, with a live search filter. Great for debugging Mixin conflicts during development.

All features are keybind-accessible (unbound by default, set them in Controls). No server-side component required.

This mod is intended for mod developers. It exposes internal game state and tooling that is not useful for normal gameplay.
