Regens Hitbox Settings
by uokik
Regens Hitbox Settings lets a player switch hitbox visibility on for each entity type, from mobs to other players.
What it does
The mod is a lightweight Fabric utility for the client. Hitboxes can be toggled per entity type across the whole game, covering mobs, players, dropped items and the player's own hitbox. Player state options (sneaking, swimming or crawling, and elytra flying) are included as settings, and the mod notes it works alongside Combat Hitboxes.
Settings are organized into built-in presets. Each preset can be imported, copied, refreshed or opened from the presets menu, and the active preset is shown on screen so configuration stays simple to follow. Presets can be shared as JSON files. Cloth Config API is required, and Mod Menu is optional for opening the settings screen.
Installation covers 1.21.11 only. Files are published for Fabric, released under All rights reserved, and the mod is not open source.
Key features
Per-entity hitboxes
Hitbox display can be turned on or off separately for each entity type, so only the chosen kinds are outlined.
Built-in presets
Presets store a full hitbox setup and can be imported, copied, refreshed or opened directly from the presets menu.
JSON preset sharing
Preset files are plain JSON, so a setup can be exported and passed to another player.
Player state options
Hitboxes can reflect sneaking, swimming, crawling and elytra flying, so the box matches the player's posture.

Use cases
Checking entity collision
A player debugging a mob or a block-adjacent entity can enable only that entity type and see where its box sits.
Sharing a setup
A group of players can agree on one preset and load the same JSON file, so everyone sees hitboxes the same way.
Who it’s for: Players and content creators who want to inspect entity hitboxes on the client, including those who record or stream gameplay.
How it compares
Only Elytra Hitbox is client-side only and shows hitboxes for elytra flight alone, with files for 1.21.1 – 1.21.11 under the CC0 1.0 Universal license. My Hitbox is also client-side only, is published for 1.21.11, and is not open source under All rights reserved. Regens Hitbox Settings covers entity types and presets as well, and is likewise not open source.
