GOWebServer

GOWebServer is a web server for Growtopia Private Server. It is written in Go and is designed to be fast and efficient.

Features

• HTTP/HTTPS server with TLS support
• Handle /growtopia/server_data.php requests
• Advanced DDoS protection (rate limiting, connection tracking, IP blacklisting)
• Proxy detection with circuit breaker pattern
• Cache server for Growtopia Client with CDN fallback
• Geo Location blocking based on country codes

Build

Using Pre-built Binary

Download the pre-built binary for your operating system from the releases page:

• Windows: Download GOWebServer-windows-amd64.zip
• Linux: Download GOWebServer-linux-amd64.zip
• macOS: Download GOWebServer-darwin-amd64.zip

Extract the archive and run the executable.

Building from Source

The following are required to build and run GOWebServer:

• Golang (1.16+) - The Go Programming Language
• and little bit of brain cells (optional)

Building the server is simple, just run the following command:

1. Clone the repository:

git clone https://github.com/yoruakio/GOWebServer.git
cd GOWebServer

2. Build the server:

go build

# or running the go file directly
go run main.go

3. Run the server:

./GOWebServer

Note

DDoS Protection (Optional but Recommended)

The server includes built-in application-layer DDoS protection (connection rate limiting, concurrent connection limits).

For additional OS-level protection against TCP SYN floods, UDP floods, and ICMP floods, run:

sudo ./scripts/setup-ddos-protection.sh

This configures kernel parameters and iptables rules for network-layer attack mitigation. Only required for Linux systems.

Configuration

The server can be configured using the config.json file. The following are the default configuration:

{
    "host": "127.0.0.1", // ENet Host
    "port": "17091", // ENet Port
    "serverCdn": "default", // Growtopia CDN to handle missing files ( default: 0098/0181220253/ - 5.39 )
    "loginUrl": "default", // URI for client login ( default: gt-login.vercel.app - 31-12-2025 update )
    "isLogging": false,
    "rateLimit": 300,
    "rateLimitDuration": 5,
    "enableGeo": false, // Enable Geo Location blocking
    "trustedRegions": [ // List of trusted regions that allow access to the server
        "ID",
        "SG",
        "MY"
    ]}
