All three are free, open-source, and install with a single command over SSH. Install just the Installer to start — it can add the other two for you later.
The starting point. A click-through dashboard that sets up everything Crafty needs — Docker, the Crafty container itself, and Cockpit + Navigator for when you need to poke at the filesystem directly.
A companion dashboard for finding, installing, and updating mods, plugins, and datapacks from Modrinth and CurseForge — matched exactly to a server's Minecraft version and loader.
The central hub — links to the other two apps, one place to check for and apply Crafty/Docker/Cockpit updates, scheduled world backups, an RCON console, whitelist/ops/ban management, and a log & crash analyzer.
