Highlight It
by Esamy
Highlight It, a Fabric client-side utility, lets players pick a custom outline color for individual mobs in the world.
What it does
Highlight It draws a colored outline around selected mobs, so a player can keep track of a specific creature in a crowd or across a wide area. The highlight is applied on the player's own client, and it works for Hypixel Skyblock-style play where marking a target matters. Because it is a client-side mod, nothing needs to change on the server, and a player can use it in single-player as well.
The mod is built on Fabric Loader and depends on Fabric API and Fabric Language Kotlin, both of which must be installed alongside it. The mod was written to cover a specific need for mob highlighting, and it is distributed under the MIT License without being open source in the usual sense of publishing its full project. Builds exist for 1.21.10 and 1.21.11, with 1.0.0 for 1.21.11 as the latest file, first published on 2026-03-21.
Key features
Custom mob highlight color
Each targeted mob can be outlined in a color the player chooses, making it easier to pick out in a busy area.
Mob-focused highlighting
The highlight is tied to individual mobs rather than blocks or items, which suits hunting, tracking and boss fights.
Client-only operation
The outline is drawn on the player's own screen, so the highlight is not seen by other players.

Skyblock-style hunting

Who it’s for: Players of Fabric who want to see specific mobs more clearly on their own screen, either in single-player or on a multiplayer server they join.
