XMCL
An open-source, cross-platform Minecraft launcher with a modern UI and disk-efficient mod management.
What is XMCL?
XMCL (X Minecraft Launcher) is an open-source launcher for the Minecraft game. It provides a modern, user-friendly interface for downloading, managing, and launching Minecraft, along with its mods and modpacks. It solves the problem of disk inefficiency by using symbolic links to avoid storing duplicate mod files across different game instances.
Minecraft players who use mods and want a more efficient, feature-rich launcher than the official one. It's particularly useful for power users managing multiple modded instances.
Developers choose XMCL for its disk-efficient mod management, integrated mod discovery from major platforms, clean modern UI, and advanced features like peer-to-peer LAN play, which aren't available in the standard launcher.
Overview
An Open Source Minecraft Launcher with Modern UX. Provides a Disk Efficient way to manage all your Mods!
Use Cases
Best For
- Managing a large collection of Minecraft mods without wasting disk space
- Running multiple isolated Minecraft instances for different modpacks
- Downloading and installing mods directly from CurseForge and Modrinth
- Playing Minecraft multiplayer over virtual LAN networks
- Using a modern, feature-rich launcher on Windows, macOS, or Linux
- Importing and exporting CurseForge and Modrinth modpacks easily
Not Ideal For
- Players who only use vanilla Minecraft without any mods and prefer the official launcher's simplicity
- Users on low-spec computers where Electron's memory and disk footprint is prohibitive
- Environments requiring mobile or web-based launcher access, as XMCL is desktop-only
- Teams needing built-in server management tools or advanced parental controls not covered by the launcher
Pros & Cons
Pros
Built on Electron, it runs on Windows, macOS, and Linux, offering a consistent modern interface across all major desktop OSes, as stated in the README.
Uses hard and symbolic links to share mods between instances, avoiding duplicate files and significantly reducing disk space waste compared to traditional launchers.
Directly downloads mods and modpacks from CurseForge and Modrinth within the app, streamlining the installation process without needing external browsers.
Includes peer-to-peer LAN play for multiplayer over virtual networks, a unique capability not commonly found in other Minecraft launchers.
Cons
The Electron framework results in higher RAM usage and larger app size than native alternatives, which can impact performance on older or resource-constrained systems.
Reliance on symbolic links for mod management may confuse non-technical users and lead to file system issues if mishandled, especially on Windows where they are less common.
Mod download functionality depends on third-party services like CurseForge and Modrinth; API changes or downtime could break features without prompt updates from the development team.
