Core Feature

The Java Management Revolution

No more UnsupportedClassVersionError. Ever.

What changed

Version 2.0.0 introduces a revolutionary Automatic Java Management system that handles all Java version compatibility issues.

No More Version Errors

The app detects the required Java version from your server JAR automatically. No more UnsupportedClassVersionError.

Isolated Runtimes

Java 8, 17, and 21 are downloaded automatically and used only for your servers. Each server gets the exact runtime it needs.

Zero Configuration

You don't need to install Java on your system manually anymore. Just create a server and hit start.

Supported: Java 8, 17, 21 — covering all Minecraft versions from 1.7 to latest.
