X Minecraft Launcher

Overview

X Minecraft Launcher (XMCL) is a free, open-source desktop launcher for Minecraft worlds and game resources. It suits players who maintain several modded setups or want more control over mods and saves. Its broad toolkit is useful for Java play, but Bedrock support is experimental and the project is independent of Mojang and Microsoft.

Key features

XMCL keeps game instances separate across Forge, Fabric, Quilt, NeoForge, OptiFine, and LabyMod. That makes it a practical option for players who switch between different modded configurations and want to keep their setups organized; experimental Bedrock support is not a firm basis for a Bedrock-focused choice. Modpacks can be imported and browsed through a built-in marketplace connecting projects from Modrinth, CurseForge, and FTB.

The launcher also manages resource packs, shader packs, Java runtimes, and installed mods. Dependency inspection and custom mod groups help users understand and organize a setup rather than merely install files. Automatic updates reduce launcher maintenance, while export tools can package modpacks and local server files for sharing.

World management is a meaningful differentiator: users can preview saves, select, copy, or delete chunks, and inspect structures in 3D. Authentication options include Microsoft, offline, and third-party services such as Ely.by and LittleSkin. XMCL says telemetry is disabled by default and only processed if enabled in settings; it also says it does not process or store Microsoft passwords, credentials, or session tokens.

Pricing

XMCL costs nothing. The free, open-source plan includes the launcher, with no paid tier described. That makes it suitable for players who want instance and resource management without a launcher subscription. The project directs issue reports to GitHub and community support to Discord.

Platforms

XMCL provides desktop packages for Windows, macOS, and Linux. It is not a mobile launcher.

Who it's for

Choose XMCL if you regularly move among modded Minecraft instances, want a combined catalog and mod-management workflow, or need tools for inspecting and editing worlds. It is less suitable if you require established Bedrock support or specifically want an official Mojang or Microsoft product: XMCL is an independent project operated by CI010 and the Voxelum contributor community, and is not approved by or associated with either company.

Pros and cons

• Pros: Separate instances cover six named mod-loader and client options, making it easier to keep configurations apart.
• Pros: The marketplace aggregates modpacks and projects from Modrinth, CurseForge, and FTB, while import and export support sharing setups.
• Pros: Save previews, chunk operations, and 3D structure previews extend the launcher beyond installation and mod upkeep.
• Pros: Telemetry is off unless enabled, and XMCL says it does not handle Microsoft account credentials or tokens.
• Cons: Bedrock support is experimental, so Bedrock players should not rely on it as a core capability.
• Cons: It is an independent, unofficial project, which may not suit players seeking a Mojang- or Microsoft-affiliated launcher.

Alternatives

Browse Minecraft Launchers for more options. Prism Launcher is another free, open-source option for Windows, macOS, and Linux; choose between them based on whether XMCL's world tools and its Modrinth, CurseForge, and FTB marketplace suit your needs. Refract is also free and supports the same desktop platforms, making it another option to compare.

LabyMod offers a free Minecraft Java Edition launcher for Windows, macOS, and Linux, with support for more than 20 versions, as well as a paid Laby+ plan; consider it if that version coverage is your priority. Spectra Launcher is a free desktop program for Windows, macOS, and Linux. GDLauncher is free on those platforms, with no premium tier or overlay. ATLauncher is a free, open-source desktop option, but requires a paid Minecraft account to use the launcher and play modpacks. Thendrask Launcher has a free MIT-licensed plan with no subscription requirement, plus an End Crystal plan at $3 a month for project support. Cactus MC Launcher is free forever, open-source, ad-free, and available for Windows, macOS, and Linux.

Verdict

XMCL is a strong choice for desktop players who want separate modded instances, a multi-source modpack catalog, and unusually capable world tools in a free launcher. Look elsewhere if experimental Bedrock support is not enough or you require an official Minecraft product.
