Code Comparison

SubCrawler (Kotlin):

fun parseClash(text: String): List<Sub> {
    return parseYaml(text).proxies?.map { proxy ->
        Sub(
            type = proxy.type,
            name = proxy.name,
            server = proxy.server,
            port = proxy.port
        )
    } ?: emptyList()
}

subconverter (C++):

void rulesetToClash(YAML::Node &base_rule, std::string &rule_name, std::string &custom_port)
{
    base_rule["name"] = rule_name;
    base_rule["type"] = "http";
    base_rule["behavior"] = "classical";
    base_rule["path"] = "./ruleset/" + rule_name + ".yaml";
    if(!custom_port.empty())
        base_rule["url"] = "http://www.gstatic.com/generate_204";
}

The code snippets show different approaches to handling configuration data, with SubCrawler focusing on parsing and subconverter on generating rule sets.

Pros of ACL4SSR

• More comprehensive rule sets for various applications and services
• Regular updates and maintenance by an active community
• Includes pre-configured lists for popular platforms like Clash and Quantumult X

Cons of ACL4SSR

• Primarily focused on Chinese websites and services
• May require more manual configuration for non-Chinese users
• Less flexibility in customizing individual rules compared to SubCrawler

Code Comparison

SubCrawler:

fun crawlSubscription(url: String): List<String> {
    val response = client.newCall(Request.Builder().url(url).build()).execute()
    return response.body?.string()?.split("\n") ?: emptyList()
}

ACL4SSR:

payload:
  - DOMAIN-SUFFIX,googleapis.cn
  - DOMAIN-SUFFIX,googleapis.com
  - DOMAIN-SUFFIX,google.cn
  - DOMAIN-SUFFIX,google.com

SubCrawler focuses on crawling and processing subscription URLs, while ACL4SSR provides pre-defined rule sets in YAML format. SubCrawler offers more flexibility for custom crawling and processing, whereas ACL4SSR provides ready-to-use rules for popular services and platforms.

Pros of sub-web

• User-friendly web interface for subscription conversion and management
• Supports multiple subscription formats and protocols
• Easy deployment with Docker

Cons of sub-web

• Limited crawling capabilities compared to SubCrawler
• Less frequent updates and maintenance
• Fewer advanced features for proxy testing and filtering

Code Comparison

sub-web (Vue.js component):

<template>
  <div class="subscription-card">
    <el-input v-model="url" placeholder="Enter subscription URL"></el-input>
    <el-button @click="convertSubscription">Convert</el-button>
  </div>
</template>

SubCrawler (Kotlin code):

fun crawlSubscriptions(urls: List<String>): List<Proxy> {
    return urls.flatMap { url ->
        val response = httpClient.get(url)
        parseProxies(response.body)
    }
}

Summary

SubCrawler focuses on crawling and aggregating proxy subscriptions, offering more advanced features for proxy testing and filtering. It's primarily a command-line tool written in Kotlin.

sub-web provides a web-based interface for subscription conversion and management, making it more accessible for users who prefer a graphical interface. It's built with Vue.js and supports various subscription formats.

Both projects serve different use cases within the proxy management ecosystem, with SubCrawler being more suitable for advanced users and automation, while sub-web caters to those seeking a user-friendly web interface for subscription handling.

Pros of Share-SSR-V2ray

• Provides a curated list of SSR and V2Ray servers, making it easier for users to find reliable connections
• Includes detailed instructions and tutorials for setting up various VPN clients
• Regularly updated with new server information and configuration guides

Cons of Share-SSR-V2ray

• Less automated than SubCrawler, requiring manual updates and maintenance
• Limited to specific VPN protocols (SSR and V2Ray), while SubCrawler supports a wider range
• Lacks built-in tools for testing or validating server connections

SubCrawler (build.gradle.kts):

dependencies {
    implementation("org.jsoup:jsoup:1.14.3")
    implementation("com.squareup.okhttp3:okhttp:4.9.3")
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.6.0")
}

The code comparison shows that Share-SSR-V2ray primarily consists of markdown files with server information, while SubCrawler is a Kotlin-based project with dependencies for web scraping and asynchronous programming.
