ComposterHUD
ComposterHUD shows a composter's exact fill level in a small readout, so a player can tell when the bone meal is ready to harvest.
What it does
Aim the crosshair at a composter and a compact readout shows up in the upper-left part of the display. It reports the exact compost height from 0 to 8, which tells how close the block is to producing bone meal. At level 8 the readout marks the composter as ready, so the moment to harvest is clear without opening the block.
The readout can be switched on or off, and an action-bar message confirms the current state each time it changes. The mod works as a clean information layer for farmers who keep composters in a crop or bone meal setup. It is a client-side only mod: the server does not need it, and players join without installing it. Fabric API is required and must be installed alongside ComposterHUD. The mod is released under the MIT License and is not open source. Files exist for Minecraft 1.21.8, 1.21.9, 1.21.10 and 1.21.11, and the latest build is 1.0.0 for 1.21.11, published on 2026-06-14.
Key features
Exact fill level
The readout shows the composter's compost height as a number from 0 to 8, not just a visual layer.
Ready indicator
At level 8 the readout states that bone meal is ready, so the block can be harvested at the right moment.
Toggle and confirmation
The readout can be turned on or off, and an action-bar message confirms the new state.

How it compares
BlockBuddy is a client-side Fabric mod for 1.21.1 – 1.21.11 under All rights reserved, so it is not open source. Totally Balanced Bone Drops is a client and server mod for Fabric and Quilt on 1.18 – 1.19.4, released under the MIT License and open source, so it changes bone drops rather than showing composter levels. ComposterHUD covers only the composter readout, on Fabric for 1.21.8 – 1.21.11.
