Beacon Bounding Box
by SamIsPoggers
Beacon Bounding Box draws a colored 3D box around each beacon to show the area its effect reaches, for players who manage large bases.
What it does
The mod is a lightweight client-side utility. Each beacon in the world gets a randomly assigned color, and its effect range appears as a bounding box drawn in that color, which lets players tell several overlapping beacons apart. Conduits are covered too: a sphere shows the area a conduit affects, so beacon and conduit coverage can be checked visually.
Display options are set in the mod's configuration. A box mode switch changes between outlined boxes and filled boxes, and the opacity of the box walls is configurable. The overlay is toggled with the H key by default, and shader support is not expected. Because the mod is client-side only, servers run without it and players join without installing anything.
Installation needs Fabric API and YetAnotherConfigLib (YACL) on Fabric or Quilt. Mod Menu is optional and gives access to the settings screen. Files exist for 1.21.1 – 1.21.11, and the latest build is 1.2 for 1.21.11, released under All rights reserved, so the source code is public but the mod is not open source.
Key features
3D effect range boxes
Each beacon's effect area is drawn as a 3D bounding box, so its reach is visible in the world.
Random beacon colors
Every beacon receives a unique randomly generated color, separating neighboring beacons whose ranges overlap.
Conduit spheres
A sphere is rendered around conduits to show the area their effect covers.
Box mode and wall opacity
A switch toggles between outlined and filled boxes, and the opacity of the walls can be adjusted in the config.
Beacon Extender compatibility
The mod works with the Beacon Extender mod, so extended beacon ranges are shown.

Use cases
Who it’s for: Players building large bases with many beacons or conduits, who want a clear visual reference for effect ranges. Because only the client needs the mod, it is useful in single-player and on multiplayer servers without any server-side install.
How it compares
Beacon Range is open source under the MIT License, client-side only, and covers 1.21.1 – 1.21.11 on Fabric, so it is the closest match in version range. BeaconHUD is also client-side only and under the MIT License, but it is limited to 1.21.8 – 1.21.11 and is not open source. Configurable Beacon Range is server-side only and targets 26.2, so it changes the range itself rather than showing it.
