Pros of v2ray-core

• Core functionality and protocol implementation
• Highly customizable and extensible
• Better performance and resource efficiency

Cons of v2ray-core

• Steeper learning curve for configuration
• Lacks user-friendly management interface
• Requires manual setup and maintenance

Code Comparison

v2ray-core (Go):

type User struct {
    Level uint32
    Email string
}

type Account struct {
    Id      string
    AlterId uint32
}

multi-v2ray (Python):

class User:
    def __init__(self, email, uuid, alter_id=0, level=0):
        self.email = email
        self.uuid = uuid
        self.alter_id = alter_id
        self.level = level

v2ray-core is the official core implementation of the V2Ray protocol, offering robust functionality and performance. It's highly customizable but requires more technical expertise to set up and manage.

multi-v2ray is a user-friendly management tool built on top of v2ray-core, providing an easier interface for configuration and user management. It simplifies the setup process but may not offer the same level of customization as the core project.

v2ray-core is written in Go, focusing on performance and efficiency, while multi-v2ray is written in Python, prioritizing ease of use and management features. The code comparison shows the different approaches to user and account management in both projects.

Pros of v2rayN

• User-friendly GUI for Windows users
• Supports multiple protocols and configurations
• Regular updates and active community support

Cons of v2rayN

• Limited to Windows platform
• May have a steeper learning curve for beginners

Code Comparison

multi-v2ray (Python):

def gen_client_json(self, port, aid=0):
    client_config = {
        "id": self.password,
        "alterId": aid,
        "email": self.email
    }
    return client_config

v2rayN (C#):

public static int GenerateRandomNumber()
{
    return new Random().Next(10000, 60000);
}

The code snippets show different approaches:

• multi-v2ray focuses on generating client configurations
• v2rayN includes utility functions like random number generation

Both projects serve different purposes:

• multi-v2ray is a server-side management tool
• v2rayN is a client-side application for Windows users

While multi-v2ray offers more flexibility for server setup and management, v2rayN provides a user-friendly interface for connecting to V2Ray servers on Windows. The choice between them depends on whether you need server management capabilities or a client application for everyday use.

Pros of v2rayNG

• User-friendly Android app with a graphical interface
• Supports multiple protocols and configurations
• Regular updates and active community support

Cons of v2rayNG

• Limited to Android platform
• May have higher resource usage compared to command-line tools

Code Comparison

multi-v2ray (Python):

def gen_client():
    client_config = {
        "v": "2",
        "ps": "",
        "add": "",
        "port": "",
        "id": "",
        "aid": "",
        "net": "",
        "type": "",
        "host": "",
        "path": "",
        "tls": ""
    }
    # ... (code to populate client_config)
    return base64.b64encode(json.dumps(client_config).encode()).decode()

v2rayNG (Kotlin):

fun getConfigString(): String {
    val config = JSONObject().apply {
        put("v", "2")
        put("ps", remarks)
        put("add", address)
        put("port", port)
        put("id", id)
        // ... (additional fields)
    }
    return Base64.encodeToString(config.toString().toByteArray(), Base64.NO_WRAP)
}

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 for configuration and setup
• Less user-friendly interface compared to multi-v2ray
• May require more manual configuration for advanced features

Code Comparison

multi-v2ray:

class V2ray:
    def __init__(self):
        self.config = Config()
        self.service = Service()

    def restart(self):
        self.service.restart()

Xray-core:

type Instance struct {
    access             sync.Mutex
    features           []Feature
    featureResolutions []resolution
    running            bool
}

func New(config *Config) (*Instance, error) {
    // Implementation details
}

The code snippets show that multi-v2ray is written in Python and focuses on a higher-level management interface, while Xray-core is implemented in Go and provides a lower-level, more performant core functionality.
