Everything you need to know about getting started with Zircon.
When you join a server and hit PLAY, Zircon compares the server's published mod list against your local client folder. Any missing or updated mods are verified via Modrinth & CurseForge SHA-512 hashes and fingerprints, then downloaded instantly without manual file dragging.
Zircon Cloud is the turnkey managed hosting platform for Zircon servers. It requires zero hardware setup or port forwarding. When no players are online, the server automatically suspends (Pause-to-Sleep) to conserve compute resources. The moment a player connects via the Zircon Launcher, the server wakes up smoothly with 100% of your world, entities, and state preserved.
