Jarock Minecraft Server Toolkit
A beginner-friendly, loader-aware Windows bootstrap for a professional Minecraft Java 26.2 server.
Jarock installs and verifies a selected server loader, configures a safe local runtime, and provides documentation for Java/Bedrock cross-play. Fabric is the recommended first choice; NeoForge is the fallback when a required mod needs it.
