Made by someone who runs a server
Crash doctor
Reads the crash and tells you what happened in plain words, then offers the fix: install the missing mod, turn one off, more memory, the right Java.
Sleep when empty
A quiet server stops by itself and frees its memory. It still shows up in the server list, and wakes the moment a friend tries to join.
Saves your world at shutdown
Turning Windows off? Craftlio stops your servers cleanly first, so nobody loses the last half hour of building.
Up and running in about five minutes
The setup asks before each step and explains what it does.
Run setup
Double-click setup.cmd. It installs Node.js if needed and sets up folders, starting with Windows and the firewall.
Open it
Your browser opens localhost:1999. Create the owner account and your first server.

Is it really free?
Yes. Craftlio is open source under the MIT licence. There's no account to make and nothing to pay. You run it on your own machine.
Does it work on Mac or Linux?
Not yet. Craftlio is built for Windows 10 and 11: it uses Windows features for starting with your machine, the firewall, and saving worlds when Windows shuts down.
How do my friends join?
Forward the game port (TCP 25565) on your router to your machine. If your domain is on Cloudflare, Craftlio can keep a name like play.example.com pointed at your home, even when your internet provider changes your address.
Can I manage it when I'm away from home?
Yes. The safest way is a free Cloudflare Tunnel, which gives Craftlio an https address without opening any ports. Phone notifications and passkeys work over it too.
Where does my data go?
Nowhere. Worlds, backups, accounts and settings stay on your machine. Craftlio goes online to download server software, Java, mods and plugins when you ask, and for things you switch on, like alerts, cloud backups or keeping your domain pointed at home.
Is Craftlio made by Mojang?
No. Craftlio is an independent project and isn't affiliated with Mojang or Microsoft. Minecraft is a trademark of Mojang AB.
