Bossclient

👑 BossClient – Be the Boss in PvP.

BossClient is a free Fabric client for Minecraft 1.21.1 – 26.3 built around PvP. It bundles 80+ modules for HUD, combat feedback, visuals and quality of life into one mod, with a modern ClickGUI, your own cape and a full minimap. You need nothing but Fabric Loader: Fabric API is already built in.

Why BossClient?

• One mod instead of twenty: HUD, minimap, waypoints, zoom, freelook, motion blur, capes and more
• Everything is configurable in a clean ClickGUI (Right Shift) with instant search in English and German
• Drag every HUD element where you want it, with snapping guides, undo and per-server profiles
• Own capes with cloth physics that other BossClient players can see
• FPS Booster and FPS target for smooth frames

HUD

Keystrokes and CPS, FPS, ping, coordinates, compass, clock, armor and durability, potion effects, item and totem counters, combo counter, reach display, target HUD, cooldowns, saturation, session stats, memory, server info, scoreboard and title scaling, colored tab-list ping, module list and notifications. Every element can be moved and scaled in the HUD editor.

PvP feedback

Reach ring that turns green when your opponent is in hit range, combat mode that hides capes, particles and far mobs during fights, hit color, hit marker, hit particles, kill effect, totem pop effects and pop counter, health warning, health in name tags, hit timing, low shield, low fire, sword color and hand item tweaks, custom crosshair, no hurt shake, fixed FOV.

Visuals

Motion Blur (1.21.6+), custom sky with aurora and BossClient stars (1.21.6+) or your own images, light overlay for mob spawn spots, Texture Studio for crystals, pearls, cobwebs, totems and golden apples, inventory colors, clear water and lava, clear weather, fullbright, time changer, item physics, block outline, view bobbing options, custom loading screen and main menu, 9 color schemes.

Map and utility

Minimap and full-screen map saved per server and dimension, cave mode, waypoints with navigation, "go to last death", coordinates in chat become a "[+ Waypoint]" button. Also zoom, freelook, freecam, auto sprint, toggle sneak, command hotkeys, quick join, screenshot gallery, Spotify display with synced lyrics, sound muffler, streamer mode (F8), shulker and map previews, Auto-GG (off by default) and per-server profiles.

Capes

Pick a built-in template with the BossClient logo or your own lettering, or upload your own image. Capes have cloth physics and also show on the elytra. Other players can submit capes to the in-game marketplace. Every custom image and marketplace submission is reviewed by an admin before others can see it, and inappropriate capes can be reported in game.

BossClient badge

A small crown next to other BossClient players in the tab list and above their heads. You can hide it or stop showing it to others at any time.

Installation

1. Install Fabric Loader 0.18 or newer for your Minecraft version.
2. Download the BossClient file that matches your Minecraft version and put it into .minecraft/mods.
3. Start the Fabric profile and press Right Shift to open the ClickGUI.

Java 21 is required, or Java 25 from Minecraft 26.1 on. BossClient is tested on its own with Fabric; other Fabric mods may work but aren't officially tested.

Online features and your data

Some features talk to the BossClient server at bossclient.com, which is run by the BossClient developer:

• Capes and marketplace: to show capes, the client looks up the Minecraft UUIDs of players in your tab list. When you set, submit or report a cape, your UUID and name are verified through Mojang's session server and stored with your cape.
• BossClient badge: at start and every few hours the client tells the server that you use BossClient. The server stores your UUID and the day. Turn it off in the BossClient badge settings.
• Update notice: the client reads the version list from bossclient.com. It never downloads or installs anything by itself.

One feature talks to a third-party service instead:

• Lyrics (off by default): to show the lyrics of the song playing in Spotify, the client reads the title, artist and playback position from the Windows media controls and sends artist, title and song length to lrclib.net, a free public lyrics database that is not run by BossClient. Nothing else is sent, and nothing is sent while the Lyrics module is off.

Chat messages and your Minecraft login token are never sent to bossclient.com. Details: privacy policy.
