A total of 9 server softwares are now available in the setup wizard and panel: Vanilla, Paper, Purpur, Spigot, CraftBukkit, Fabric, Quilt, Forge and NeoForge.
Version lists are fetched live for each software; pick the Minecraft version you want and install. Setup typically takes a few minutes.
Switching between softwares happens in the panel: your current profile is backed up and the new software is installed clean. You can return to your old profile at any time.
Ready-made world templates, including superflat, are in the wizard too: instant starts for creative parkour, minigames or classic survival.
