BossBarTools
by iroaK
BossBarTools lets a player hide every boss bar on the HUD with one keypress, or hide only the bars whose titles match a filter.
What it does
Minecraft shows boss bars for the Ender Dragon, the Wither and other bosses, along with loading and progress bars that some mods and servers send. BossBarTools can hide all of them at once through a global toggle, which is on by default, or sort them with filters that match the bar's title. The mod runs on the client alone, so only the player who installs it is affected, and the server needs nothing.
The mod requires Mod Menu, which opens its configuration screen from the mod list. It is published for Fabric only, with a single build for 1.21.4, released as version 1.0.0 on 2025-10-18. The code is open source under the MIT License, and the source code is public.
Key features
Global toggle
A single keypress hides every boss bar, and the same key brings them back, without changing any game setting.
Exact match filters
A filter can match a bar title exactly, for example to hide only the Ender Dragon bar and leave the others visible.
Contains filters
A filter can hide any bar whose title contains a given word, such as loading or progress.
Regex filters
Pattern matching lets a filter catch titles with changing numbers, such as a percentage in a loading message.
Live preview
Changes made in the configuration screen take effect at once, so the result can be checked without restarting the game.

Use cases
Hiding loading bars
Contains and regex filters can remove loading and percentage bars that clutter the top of the screen during long tasks.
Who it’s for: Players who find boss bars distracting, streamers and builders who want a cleaner screen, and players who prefer to filter bars by title rather than hide all of them.
How it compares
Hide and filter mods differ mainly in what they target. More Hide Gui is a Fabric client mod under the MIT License for 1.21.11, and it hides interface elements in general rather than boss bars alone. Bossbar Hider is a Fabric client mod for 26.2 – 26.3 under the GNU Lesser General Public License v3.0 only, and it is open source. BossTimer-Mod is a server-side only mod for 1.21.1 – 1.21.11 under the GNU General Public License v3.0 only, so it does not need to be installed by players.
