What is Smartproxy (Decodo)?
Smartproxy, founded in 2018 and rebranded to Decodo in April 2025, is an enterprise proxy provider with over 65 million residential IPs across 195+ countries. The platform targets businesses requiring large-scale web scraping, ad verification, and market research capabilities.
Decodo offers residential, datacenter, and mobile proxies alongside specialized APIs for SERP scraping, social media, and e-commerce data collection. Their Site Unblocker feature automatically handles CAPTCHAs and anti-bot measures.
Decodo vs CorsProxy.io
Decodo and CorsProxy.io serve entirely different markets:
Target Use Case: Decodo is built for server-side web scraping operations requiring IP diversity. CorsProxy.io solves browser-based CORS restrictions for frontend applications.
Browser Support: Decodo proxies require server configuration or browser extensions. CorsProxy.io works natively in browsers with a URL change.
// Decodo requires proxy configuration
// Server-side only - cannot run in browser
import axios from 'axios';
const response = await axios.get(url, {
proxy: {
host: 'gate.decodo.com',
port: 10001,
auth: { username: 'user', password: 'pass' }
}
});
// CorsProxy.io works directly in browsers
const response = await fetch(
`https://corsproxy.io/?url=${encodeURIComponent(url)}`
);
Pricing Analysis
Decodo’s pricing favors high-volume enterprise users:
| Plan | Decodo | CorsProxy.io |
|---|---|---|
| Free | 100MB trial (3 days) | 10,000 req/month |
| Entry | ~$100/mo (varies) | $9/month |
| Billing | Per GB | Per request |
| Predictability | Variable | Fixed monthly |
Use Case Alignment
Choose Decodo if:
- You’re running server-side scrapers
- You need millions of unique IPs
- You’re collecting data from protected sites
- You have enterprise-level budgets
Choose CorsProxy.io if:
- You’re fixing CORS errors in web apps
- You need browser-native solutions
- You want predictable, simple pricing
- You’re building frontend applications
The CORS Problem Decodo Can’t Solve
Browser CORS errors happen because browsers block JavaScript from making cross-origin requests without proper headers. No amount of IP rotation or proxy configuration fixes this—the browser itself enforces these restrictions.
CorsProxy.io specifically addresses this by:
- Receiving your request at a CORS-enabled endpoint
- Fetching the target resource server-side
- Returning it with proper CORS headers
This browser-native approach is impossible with traditional proxy services like Decodo.
