Exposed

Exposed is a lightweight client-side profiler for Minecraft. It measures integrated-server tick time and TPS, ranks the block entities and entities that cost the most, and highlights them in-world with color-coded labels. Toggle it with a keybind to find lag sources at a glance.

This is a successor of LagGoggles, and a reboot of Observable for modern versions.

Fabric Api is required. ModMenu is recommended, although all settings are accessible through the pause menu.

Usage

To toggle profiling, press I. Profiling is available in singleplayer worlds and on servers running Exposed.

Profiling in servers require permission. Exposed uses a whitelist system, which can be manipulate using the /exposed command. Note that operator status alone does not grant profile access; the singleplayer owner is allowed automatically.
