Hytale F2P - Dedicated Server

Host your own Hytale server. The scripts handle everything automatically.

Prerequisites

• Java 25+ — Windows installer | Other platforms
  • If you have the F2P launcher installed, its bundled Java will be used automatically
• Internet connection for first launch (downloads ~3.5 GB of game files)
  • If you have the F2P launcher installed, game files are copied locally (no download needed)

Quick Start

Windows

1. Download start.bat to an empty folder
2. Double-click start.bat
3. Done — server starts on port 5520

Linux / macOS

mkdir hytale-server && cd hytale-server
curl -O https://raw.githubusercontent.com/amiayweb/Hytale-F2P/develop/server/start.sh
chmod +x start.sh
./start.sh

What the scripts do

1. Search for the F2P launcher install (default paths + custom installPath from config)
2. Use bundled Java from the launcher, or fall back to system Java (25+ required)
3. Copy game files from the launcher install if available
4. Download missing files: HytaleServer.jar (~150 MB), Assets.zip (~3.3 GB), dualauth-agent.jar (~5 MB)
5. Check for updates on every launch (server, assets, and agent)
6. Generate a persistent server ID
7. Fetch authentication tokens
8. Start the server with dual-auth support

Connecting

• Same PC: Connect to localhost:5520 or 127.0.0.1:5520
• LAN: Connect to your local IP (e.g. 192.168.1.x:5520)
• Internet: Forward port 5520 (TCP + UDP) on your router, friends connect to your public IP

No public IP? Use playit.gg (recommended)

If you're behind CGNAT or can't port forward, playit.gg gives you a public address for free:

1. Go to playit.gg and create an account
2. Download and run the playit agent
3. Create a tunnel — select Hytale as the game type, local port 5520
4. Share the generated address with friends (e.g. something.joinplayit.gg:12345)

Other options

• Radmin VPN — virtual LAN, all players must install it
• ZeroTier — same idea, create a network, friends join and connect via VPN IP

Configuration

Set environment variables before running the script:

Variable	Default	Description
SERVER_NAME	My Hytale Server	Server name shown in listings
BIND_ADDRESS	0.0.0.0:5520	IP and port to listen on
JVM_XMX	(Java default)	Max memory (e.g. 4G, 8G)
JVM_XMS	(Java default)	Initial memory
AUTH_MODE	authenticated	Auth mode (authenticated or none)
HYTALE_AUTH_DOMAIN	auth.sanasol.ws	Auth server domain
DOWNLOAD_BASE	https://download.sanasol.ws/download	File download URL

Example (Linux):

SERVER_NAME="Epic Server" JVM_XMX=4G ./start.sh

Example (Windows):

set SERVER_NAME=Epic Server
set JVM_XMX=4G
start.bat

Troubleshooting

Problem	Solution
java not found	Install the F2P launcher (includes Java) or install Java 25+ from adoptium.net
Download fails	Check internet connection. Files can be downloaded manually from https://download.sanasol.ws/download/
Port already in use	Change port: BIND_ADDRESS=0.0.0.0:5521 ./start.sh
Out of memory	Set more RAM: JVM_XMX=4G ./start.sh
Friends can't connect	Forward port 5520 (TCP+UDP) on your router, or use playit.gg if you can't port forward
