Bat Client.
Built to be faster.
Bat Client by Raven is a free Minecraft Java launcher with game profiles, performance tools and a companion Fabric mod. This is the official website: batclient.xyz.
Bat Client is an independent project, unrelated to BatMod at batmod.com. About Bat Client and the difference →
Most "performance" clients are just a list of mods stapled together. We took the opposite approach — fewer moving parts, less to conflict, more to gain.
The stuff that's actually different
Features (not a sales pitch)Frames that don't drop mid-fight
Bat Client tunes chunk rendering and memory allocation so your FPS stays steady when everything happens at once, instead of tanking right when it matters. It adapts render distance to what your GPU is actually handling.
Input that goes straight to the game
We skip the extra processing steps between your mouse and the screen. The result is a more direct, more responsive feel in PvP — no added layers deciding to slow you down.
A HUD you actually set up your way
Move, resize, recolor, or hide every HUD element — keystrokes, armor, a reach counter. Drag and drop it where it works for you, or pull a preset from the community.
Forge & Fabric
Runs the versions you actually play — from the legacy 1.7.10–1.12.2 days on Forge to modern Fabric on 1.16.5 and up.
Your mods included
Bring your own mods and cosmetics. Bat Client plays nice with most utility and visual mods — it just doesn't stack two performance mods on top of each other.
Setup in minutes
The installer spots your Minecraft folder and Java automatically. No config files to hunt down, no steps to break. You're in game fast.
