Everything you need to get online.

The website is delivered from Cloudflare. The Windows helper runs on the host computer. The Minecraft Java process and its files remain on that computer. When the helper is online, the browser can manage it through the local API.

1. Download PixelServersSetup.exe from the Download page.
2. Open it on the computer that will host the world.
3. Allow Node.js and Java through Windows Firewall on Private networks when Windows asks.
4. Return to PixelServers and open Dashboard.
5. Create a server, wait for installation, then press Start.

The helper downloads runtimes and server software as needed. Keep the computer awake while the server is running.

For the same home network, players use the local IPv4 address shown in the server page. The website cannot configure your router for you.

• Browser prompt: choose Allow if your browser asks to find devices on the local network.
• Windows Firewall: allow Java on Private networks. Do not allow the helper API publicly.
• Router: use a fixed local IP and forward only the Minecraft TCP port.

To use a subdomain such as alex.pixelservers.net, the DNS record must point to Alex’s public IP or to a Minecraft-compatible relay. DNS-only records are used for direct Minecraft connections; Cloudflare’s regular web proxy is not a Minecraft TCP relay.

Users behind CGNAT need a relay or tunnel. A public hostname never makes a sleeping PC or stopped helper reachable.

• Keep 127.0.0.1:41815 private.
• Use online-mode=true unless you understand the security implications.
• Keep Java, Minecraft, loaders, mods, and plugins updated.
• Back up worlds independently.
• Never install untrusted JAR files or give strangers remote access to your PC.
