Fullerbright
Fullerbright is a Fabric client mod that raises Minecraft brightness past the normal limits with a command-based fullbright option.
What it does
Players who play in dark caves, nights or unlit builds can turn on a brightness boost that goes beyond the game's usual maximum. The boost is toggled through simple client-side commands, so there is no screen to navigate and no item to craft. The original brightness setting is restored whenever the boost is turned off, which leaves the normal options unchanged.
The mod is designed for players who want extra visibility without installing a shader or texture pack. Because it is lightweight and avoids heavy rendering work, it is described as performance-friendly for everyday play. Installation needs Fabric Loader and Fabric API. Only the client needs Fullerbright, since it is client-side only and the server does not have to run it. The server still has to be installed where the world is hosted for the commands to work in that context, and the mod is published only for 1.21.11.
Key features
Extreme brightness boost
A command turns on a brightness level beyond the normal range, making dark areas much easier to read.
Simple client-side commands
Fullbright is toggled with a short command, so it can be switched on and off in the middle of play.
Original setting restored
When the boost is disabled, the brightness setting returns to its original value.
Lightweight design
The mod is small and avoids extra rendering passes, keeping its effect on frame rate low.

Use cases
Exploring dark caves
Caves and mineshafts that have no torches become readable without carrying extra light sources.
Night-time building
Builders working after dark can check block placement and colors without waiting for daylight.
Who it’s for: Players on Fabric who want more visibility in dark places, and builders who need to see their work at night. The mod is not aimed at server owners beyond providing the commands on their side.
How it compares
FXBright is a Fabric client mod under the MIT License, published for 1.21 – 26.2, and it is not open source. Gurozege48 Fullbright is also client-side only and works only on 1.21.11, under All rights reserved. Fullerbright matches that single version but is licensed the same way, so the choice comes down to which command style a player prefers.
