What is Minecraft Overlay?
Minecraft Overlay is a modern in-game overlay for Minecraft that lets you browse, multitask, and access useful tools without leaving the game.
The mod adds a clean desktop-style interface with draggable windows, widgets, notes, calculators, timers, themes, and an optional embedded browser system.
Designed to feel lightweight and modern, Minecraft Overlay focuses on convenience, customization, and usability while staying integrated directly into Minecraft.

Server lagging with MCOverlay – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if MCOverlay consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
