Pros of shadowsocks-rust

• Written in Rust, offering better performance and memory safety
• More focused on the Shadowsocks protocol, potentially providing better optimization
• Active development with frequent updates and bug fixes

Cons of shadowsocks-rust

• Limited to Shadowsocks protocol, less versatile compared to gost's multi-protocol support
• May have a steeper learning curve for users not familiar with Rust
• Fewer built-in features compared to gost's comprehensive toolset

Code Comparison

shadowsocks-rust:

let server = ShadowsocksServer::new(config)?;
server.run().await?;

gost:

ln, err := gost.TCPListener(node.Addr)
if err != nil {
    return err
}
h := gost.NewServer(handler, ln)

Both projects use concise code for server setup, but gost offers more flexibility in protocol selection and handling.

Pros of v2ray-core

• More comprehensive protocol support, including VMess, VLESS, and Trojan
• Advanced routing capabilities with flexible rule-based traffic routing
• Better documentation and community support

Cons of v2ray-core

• More complex configuration and setup process
• Higher resource consumption due to its extensive feature set
• Steeper learning curve for new users

Code Comparison

v2ray-core configuration example:

{
  "inbounds": [{
    "port": 1080,
    "protocol": "socks",
    "settings": {
      "auth": "noauth"
    }
  }],
  "outbounds": [{
    "protocol": "freedom"
  }]
}

gost configuration example:

gost -L=:8080 -F=ss://method:password@host:port

Key Differences

• gost is more lightweight and easier to set up for simple proxy scenarios
• v2ray-core offers more advanced features and customization options
• gost focuses on simplicity and ease of use, while v2ray-core prioritizes flexibility and security

Use Cases

• gost: Quick and simple proxy setup for basic needs
• v2ray-core: Complex network environments requiring advanced routing and protocol support

Community and Development

• v2ray-core has a larger and more active community
• gost has fewer contributors but maintains a focused development approach

Pros of Trojan

• Designed specifically for censorship circumvention, offering better obfuscation
• Simpler configuration and setup process
• Lighter resource usage, especially on low-end devices

Cons of Trojan

• Less versatile, primarily focused on proxy functionality
• Smaller community and fewer third-party implementations
• Limited protocol support compared to GOST's multi-protocol approach

Code Comparison

Trojan (server configuration):

{
    "run_type": "server",
    "local_addr": "0.0.0.0",
    "local_port": 443,
    "remote_addr": "127.0.0.1",
    "remote_port": 80,
    "password": ["password1"],
    "ssl": {
        "cert": "/path/to/certificate.crt",
        "key": "/path/to/private.key"
    }
}

GOST (server configuration):

gost -L=ss://chacha20:password@:8338

Trojan focuses on a specific proxy implementation with a more detailed configuration, while GOST offers a concise command-line interface for various protocols. Trojan's configuration is JSON-based, providing clear structure, whereas GOST uses a more compact string-based format for quick setup.

Both projects serve as proxy tools, but Trojan is tailored for censorship bypass, while GOST offers a broader range of networking capabilities. The choice between them depends on specific use cases and required features.

Pros of kcptun

• Focuses specifically on KCP protocol optimization, potentially offering better performance for certain use cases
• Simpler setup and configuration for basic KCP tunneling needs
• Lighter weight and more specialized than the broader feature set of gost

Cons of kcptun

• Limited to KCP protocol, while gost supports multiple protocols and transport methods
• Lacks the extensive proxy chaining and routing capabilities provided by gost
• May require additional tools or configurations for more complex networking scenarios

Code Comparison

kcptun (client configuration):

kcptun_client := &KCPClient{
    RemoteAddr: "server_ip:port",
    Key:        "your_encryption_key",
    Mode:       "fast2",
    Conn:       4,
}

gost (similar functionality):

gost.Run(
    "kcp://server_ip:port?crypt=aes&key=your_encryption_key&mode=fast2",
    "socks5://:1080",
)

Both projects aim to improve network performance and security, but gost offers a more comprehensive solution with support for various protocols and advanced features, while kcptun specializes in optimizing KCP connections.

Pros of trojan-go

• Focuses specifically on the Trojan protocol, offering optimized performance for this use case
• Includes built-in support for WebSocket and other transport layers
• Provides a user-friendly web-based management interface

Cons of trojan-go

• More limited in protocol support compared to gost's multi-protocol capabilities
• May have a steeper learning curve for users not familiar with Trojan protocol
• Less frequent updates and potentially smaller community compared to gost

Code Comparison

trojan-go configuration example:

{
  "run_type": "server",
  "local_addr": "0.0.0.0",
  "local_port": 443,
  "remote_addr": "127.0.0.1",
  "remote_port": 80,
  "password": ["your_password"]
}

gost configuration example:

gost -L=ss://chacha20:your_password@:8338 \
     -L=socks5://:1080 \
     -F=ss+wss://chacha20:your_password@example.com:443

Both projects aim to provide secure proxy solutions, but they differ in their approach and focus. trojan-go specializes in the Trojan protocol, while gost offers a wider range of protocols and more flexibility in configuration. The choice between them depends on specific use cases and user preferences.

Pros of Xray-core

• More advanced protocol support, including VLESS and XTLS
• Better performance and lower latency due to optimized core
• Active development with frequent updates and improvements

Cons of Xray-core

• Steeper learning curve due to more complex configuration options
• Less versatile in terms of supported proxy types compared to gost

Code Comparison

Xray-core configuration example:

{
  "inbounds": [{
    "port": 10086,
    "protocol": "vmess",
    "settings": {
      "clients": [{ "id": "b831381d-6324-4d53-ad4f-8cda48b30811" }]
    }
  }],
  "outbounds": [{ "protocol": "freedom" }]
}

gost configuration example:

gost -L=:8080 -F=ss://method:password@1.2.3.4:8338

Summary

Xray-core offers more advanced features and better performance, making it suitable for users who require cutting-edge proxy technologies. However, it may be more challenging to set up and use compared to gost. gost, on the other hand, provides a simpler configuration and a wider range of proxy types, making it more versatile for general use cases. The choice between the two depends on specific requirements and user expertise.
