Laby Launcher delivers LabyMod, the ultimate free all-in-one client for Minecraft: Java Edition, bundling 300+ mods, 3D voice chat, cosmetics and a modern launcher into a single download for Windows, macOS and Linux. Beyond LabyMod, the launcher also lets you create and run instances for Vanilla, Fabric, Forge and Quilt, so everything you play lives in one place.
What you get:
- Incredible performance - Freezes, lags and poor FPS are a thing of the past. With doubled performance your game feels smoother than ever before.
- Your game, your style - Switch at any time between a stunning, high-resolution modern theme and the classic, iconic Minecraft look.
- Built-in VoiceChat - Free in-game voice chat with 3D surround sound and proximity audio on every multiplayer server - no plugins, no setup required.
- Cosmetics with character - Handcrafted, passionately animated and highly customizable cosmetics, plus a skin and cape library with 3D preview and support for your own uploads.
- Reinvented screenshots - Capture and share 3D screenshots with automatic player tagging.
- Stay connected - A server-independent friends chat with tabs and a freely movable chat window keeps you in touch wherever you play.
- One launcher for everything - Create instances for Vanilla, Fabric, Forge and Quilt, each with its own mods and configuration, and import existing setups from launchers like MultiMC or Prism.
Note: LabyMod is not an official Minecraft product. It is not approved by or associated with Mojang or Microsoft.
