JJMC isn't just another server wrapper. It's built to make running one server (or fifty) actually enjoyable. Whether you're hosting a private SMP for friends or managing a complex modded network, we've got you covered.
Stop fighting with JAR files and command lines.
- Support for Everything: Native support for Vanilla, Fabric, Forge, NeoForge, Quilt, and Paper.
- Spigot BuildTools: We handle the annoying BuildTools compilation for you automatically.
- Version Fetching: Always see the latest valid game and loader versions.
- Import/Export: Drag and drop existing server folders to import them in seconds.
- Folders & Organization: Group your instances into folders (like "SMPs", "Test Servers") so your dashboard stays clean.
- Modrinth & Spiget Integration: Search, install, and update Mods and Plugins directly from the dashboard.
- Modpacks: One-click install for popular modpacks.
- Packwiz Support: Building your own pack? We support Packwiz natively for easy updates and distribution.

./run.shDouble click run.bat or run.ps1.
That's it. The script handles downloading the portable Go and Node.js runtimes so you don't even need to install them globally.
