Corsfix Alternative

What is Corsfix?

Corsfix is a CORS proxy service that positions itself as a modern alternative to CORS Anywhere. The service offers a free tier with 60 requests per minute, making it suitable for development and light production use.

One distinguishing feature is the ability to override request headers and modify forbidden headers, giving developers more control over how proxied requests are constructed.

Corsfix vs CorsProxy.io

Both services solve the same fundamental problem—browser CORS restrictions—but differ in approach and scale:

Infrastructure: CorsProxy.io operates on a global edge network with 300+ locations for consistent sub-50ms response times. Corsfix’s infrastructure details are less documented.

Rate Limits: Corsfix offers 60 requests/minute on free tier. CorsProxy.io provides 10,000 requests/month free, which translates to roughly 0.23 requests/minute sustained but allows burst usage.

Enterprise Features: CorsProxy.io offers dedicated support, custom SLAs, and enterprise plans for high-volume users. Corsfix’s enterprise offerings are less defined.

// Corsfix usage
const response = await fetch(
  `https://proxy.corsfix.com/?${encodeURIComponent(targetUrl)}`
);

// CorsProxy.io usage
const response = await fetch(
  `https://corsproxy.io/?url=${encodeURIComponent(targetUrl)}`
);

Feature Comparison

Choosing Between Them

Choose Corsfix if:

• You need header override features
• Your usage is consistent (not bursty)
• You’re in early development
• Minute-based rate limits work for you

Choose CorsProxy.io if:

• You need guaranteed uptime
• You want global edge performance
• You’re running production workloads
• You need enterprise support options

Migration Considerations

If you’re evaluating both services, consider:

1. Reliability History: CorsProxy.io has years of uptime data and serves major companies. Corsfix is newer with less public track record.

2. Scaling Path: CorsProxy.io offers clear paid tier progression from $9/month. Corsfix’s scaling options are less transparent.

3. Documentation: Both services provide getting-started guides, but CorsProxy.io offers more extensive documentation for advanced use cases.
