ProxyScrape Alternative

What is ProxyScrape?

ProxyScrape aggregates and maintains lists of public HTTP, SOCKS4, and SOCKS5 proxies. The service scans the internet for open proxy servers, tests their availability, and provides lists filtered by country, protocol, and anonymity level.

Beyond free lists, ProxyScrape offers premium residential proxies for users needing more reliable infrastructure. However, the primary draw is their extensive free proxy database.

The Problem with Free Proxy Lists

Public proxy lists have inherent issues:

• Reliability: Many proxies are slow, overloaded, or offline
• Security: Unknown operators could intercept traffic
• Speed: Free proxies are shared with thousands of users
• Lifespan: Proxies frequently go offline

These proxies are suitable for very specific use cases (testing, research) but not production applications.

ProxyScrape vs CorsProxy.io

These services solve completely different problems:

Purpose: ProxyScrape provides IP addresses for routing traffic. CorsProxy.io adds CORS headers so browsers accept cross-origin responses.

Browser Support: ProxyScrape proxies require system or application configuration. CorsProxy.io works natively in browser JavaScript.

Reliability: Public proxies fail frequently. CorsProxy.io guarantees 99.99% uptime.

// ProxyScrape provides proxy IPs for configuration
// Cannot be used directly in browser JavaScript

// System proxy configuration example (not browser):
// HTTP_PROXY=http://141.98.80.38:8080

// CorsProxy.io works in any browser
const response = await fetch(
  `https://corsproxy.io/?url=${encodeURIComponent('https://api.example.com/data')}`
);

Why Public Proxies Can’t Fix CORS

Even if you could configure browser proxy settings (you can’t via JavaScript), it wouldn’t fix CORS:

1. CORS is browser-enforced: The browser checks response headers
2. Proxies don’t modify headers: They just route traffic
3. The response still lacks CORS headers: Browser blocks it anyway

CorsProxy.io specifically adds the necessary Access-Control-Allow-Origin headers that browsers require.

Comparison

When Each Makes Sense

Use ProxyScrape if:

• You’re testing proxy implementations
• You need IPs for server-side tools
• You’re researching proxy technology
• Budget is absolute zero

Use CorsProxy.io if:

• You need to fix CORS errors
• You’re building web applications
• Reliability matters
• You need production-grade service
