Blocky Outline
by CharaZ
With Blocky Outline, the block under the crosshair gets a customizable outline and an optional translucent face fill, with color and rainbow options set in its own dashboard.
What it does
Blocky Outline changes how the targeted block is highlighted. The outline can be drawn around the block, filled over its faces, or both at once, and each mode can be turned on or off separately. Width, transparency and the exact color of the outline and the fill can all be adjusted, so the highlight can be made sleek and translucent or bold and solid. Players open the customizer dashboard once in-game by pressing M.
The mod is client-side only, so it runs on a single-player world or on a multiplayer server whether or not the server has it. Players on vanilla or modded servers keep their highlight settings, since the server does not need any change. The mod is published for Fabric and Forge and requires the Fabric API on Fabric. Files cover 1.19 – 26.2 with the latest Fabric file for 26.1.2 and the latest Forge file for 1.21.11, and the code is open source under the Apache License 2.0.

How it compares
Block Outline Customizer is open source under the MIT License, client-side only, and published for Fabric, Forge and NeoForge across 1.20.1 – 26.3. Color Me Outlines is also client-side only and open source under the MIT License, but it is Fabric-only and covers 1.19 – 1.20.1, so it does not reach the newer versions. Remove Block Outline is Fabric-only for 1.21.11 and is not open source, licensed as All rights reserved.
