Xget

中文

$CTAN$

Ultra-high performance, secure, all-in-one open-source resource acceleration engine. Significantly outperforms traditional accelerators, providing unified and efficient acceleration across multiple platforms including code repositories, package managers, AI inference APIs, container images, models, and datasets.

🎯 Quick Start

Public Instance: xget.xi-xu.me - Ready to use, no deployment required!

URL Converter: xuc.xi-xu.me - One-click conversion of any supported platform URL to Xget acceleration format!

⚡ Experience lightning-fast downloads instantly: No registration, no configuration needed - just start using it to feel the blazing download speeds!

🌟 Core Advantages - Why Choose Xget?

⚡ Extreme Performance - Breaking Traditional Accelerator Bottlenecks

⚡ Millisecond Response: Cloudflare's global 330+ edge nodes with average response time < 50ms
🌐 HTTP/3 Ultra-Fast Protocol: Latest HTTP/3 protocol reduces connection latency by 40% and boosts transfer speed by 30%
📦 Smart Multi-Layer Compression: Triple compression with gzip, deflate, and brotli algorithms improves transfer efficiency by 60%
🔗 Zero-Latency Pre-connection: Connection warming and keep-alive eliminates handshake overhead for instant response
⚡ Parallel Chunked Downloads: Full HTTP Range request support enables multi-threaded downloads with multiplied speeds
🎯 Intelligent Route Optimization: Automatically selects optimal transfer paths, avoiding network congestion nodes

🌐 Deep Multi-Platform Integration

Unified Multi-Platform Support: Single solution for code repositories, package managers, AI inference providers, container registries, and model/dataset hosting platforms
Smart Recognition & Transformation: Automatically identifies platform prefixes and converts to correct target platform URL structures
Consistent Acceleration Experience: Enjoy unified and stable ultra-fast download service regardless of file type or source

🔒 Enterprise-Grade Security

Multi-Layer Security Headers:
- Strict-Transport-Security: Enforces HTTPS transport, prevents man-in-the-middle attacks
- X-Frame-Options: DENY: Prevents clickjacking attacks
- X-XSS-Protection: Built-in XSS protection mechanism
- Content-Security-Policy: Strict content security policy
- Referrer-Policy: Controls referrer information leakage
Request Validation Mechanism:
- HTTP method whitelist: Regular requests limited to GET/HEAD, Git operations dynamically allow POST
- Path length limits: Prevents oversized URL attacks (max 2048 characters)
- Input sanitization: Prevents path traversal and injection attacks
Timeout Protection: 30-second request timeout prevents resource exhaustion and malicious requests

🚀 Modern Architecture & Reliability

Smart Retry Mechanism:
- Maximum 3 retries with linear delay strategy (1000ms × retry count)
- Automatic error recovery improves download success rate
- Timeout detection and interruption handling
Efficient Caching Strategy:
- 1800 seconds (30 minutes) default cache duration significantly reduces origin server pressure
- Git operations bypass cache ensuring real-time updates
- Edge caching based on Cloudflare Cache API
Performance Monitoring System:
- Built-in PerformanceMonitor class tracks request stage timing in real-time
- Detailed performance data via X-Performance-Metrics response header
- Cache hit rate statistics and optimization recommendations

🎯 Full Git Protocol Compatibility

Smart Protocol Detection:
- Automatically recognizes Git-specific endpoints (/info/refs, /git-upload-pack, /git-receive-pack)
- Detects Git client User-Agent patterns
- Supports query parameters like service=git-upload-pack
Complete Operation Support:
- git clone: Full repository cloning with shallow clone and branch specification support
- git push: Code pushing and branch management
- git pull/fetch: Incremental updates and remote synchronization
- git submodule: Recursive submodule cloning
Protocol Optimization:
- Preserves Git-specific request headers and authentication information
- Smart User-Agent handling (defaults to git/2.34.1)
- Supports Git LFS large file transfers

📱 Ecosystem Integration

Dedicated Browser Extensions: Xget Now provides seamless experience
- Automatic URL redirection without manual URL modification
- Custom Xget instance domain support
- Multi-platform preference settings and blacklist/whitelist management
- Local processing ensures privacy and security
Download Tool Compatibility: Perfect support for wget, cURL, aria2, IDM, and other mainstream download tools
CI/CD Integration: Direct usage in GitHub Actions, GitLab CI, and other environments

    - protocol: TCP
      port: 80
      targetPort: 3000
  type: LoadBalancer

Deploy to Kubernetes:

kubectl apply -f k8s-deployment.yaml

After deployment, your Xget service will be available at http://localhost:3000. You can check the service status through the /api/health endpoint.

🔧 Configuration

Configuration Parameters

You can customize configuration by modifying src/config/index.js:

export const CONFIG = {
  TIMEOUT_SECONDS: 30,       // Request timeout (seconds)
  MAX_RETRIES: 3,            // Maximum retry attempts
  RETRY_DELAY_MS: 1000,      // Retry delay (milliseconds)
  CACHE_DURATION: 1800,      // Cache duration (1800 seconds = 30 minutes)
  SECURITY: {
    ALLOWED_METHODS: ["GET", "HEAD"],  // Allowed HTTP methods (Git operations dynamically allow POST)
    ALLOWED_ORIGINS: ["*"],            // Allowed CORS origins
    MAX_PATH_LENGTH: 2048,             // Maximum path length (characters)
  },
};

Performance Tuning Recommendations

Cache Optimization: Adjust CACHE_DURATION based on usage patterns; frequently updated repositories can use lower values
Timeout Settings: Increase TIMEOUT_SECONDS for poor network conditions
Retry Strategy: Increase MAX_RETRIES and RETRY_DELAY_MS for high-latency environments

Adding New Platforms

To add support for new platforms, edit src/config/platforms.js:

export const PLATFORMS = {
  // Existing platforms...

  // New platform example
  custom: {
    base: "https://example.com",
    transform: (path) => path.replace(/^\/custom\//, "/"),
  },
};

🔍 Troubleshooting

Common Issues

Q: Download speed not significantly improved? A: Check if source files are already cached on CDN edge nodes. First access may be slower, subsequent access will be significantly faster.

Q: Git operations failing? A: Confirm correct URL format usage and that Git client version supports HTTPS proxy.

Q: Cannot access after deployment? A: Check if Cloudflare Workers domain is correctly bound and confirm wrangler.toml configuration is correct.

Q: Getting 400 errors? A: Check URL path format and confirm platform prefix is used correctly.

Performance Monitoring

The service returns performance metrics in response headers:

X-Performance-Metrics: Contains timing statistics for request stages
X-Cache-Status: Shows cache hit status

Debug Logging

In development environment, you can view detailed logs through Cloudflare Workers console:

npx wrangler dev --log-level debug
