Production CORS proxy

CORS proxy for production apps

Local demos can use CORSPROXY for free. Production apps need an API key so traffic can be tied to your allowed domain, limits, and usage dashboard.

Use in Production Try in Development

One prefix

fetch('https://corsproxy.io/?url=https%3A%2F%2Fapi.example.com%2Fdata')
  .then(response => response.json())
  .then(data => console.log(data));

When this helps

Client-side apps calling third-party APIs
Production frontends without backend proxy code
Apps that need higher rate limits and request analytics

Free for development, paid for production

Use Production when real users depend on the request path and you need caching, rewriting, scraping helpers, SLA, and support.

Production domains need an API key. Free stays focused on localhost-like development so the production path stays reliable.
