Production-ready infrastructureAPI keys, domains, support
Browsers block frontend requests when an API does not allow your website origin. CORSPROXY makes the request server-side, adds the CORS response headers your browser needs, and returns the API response to your app.
Yes. CORSPROXY is free for local development and supported development origins. Production website domains require an API key.
Yes. Add your API key to the proxy URL, authorize your production domain in the dashboard, and choose a production plan for higher limits and support.
Security and Infrastructure
CORSPROXY runs requests through edge infrastructure over HTTPS, with API keys and domain authorization for production usage. Avoid exposing private upstream secrets in browser code.
CORSPROXY does not persist the proxied response body for normal requests. Requests are processed to fetch the upstream URL and return the response to your app.
‘https://api.example.com/data’ from origin ‘https://myapp.com’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the resource.

Developer Testimonials
People love building with CORSPROXY
Discover why developers choose CORSPROXY every day.
“I’m using corsproxy.io for fetching geojson files from azure cloud.” Microsoft Geospatial Architect
“If you are getting an error saying something about “CORS” or “origin”: There’s a free “CORS Proxy” at corsproxy.io you can use.” Professor, James Madison University
“I recently discovered a simple and effective solution that can save you a lot of time and frustration. It’s called Corsproxy.”
“I used corsproxy.io to safely bypass CORS restrictions while testing from localhost.”
Why Developers Choose CORSPROXY
“Client-side access of HTTP resources is in many cases broken. That is why services like corsproxy.io exist.”
“I recommend CORSPROXY to anyone in Google community who is having issues with CORS.”
“It is awesome that CORS Proxy exists. I recommend corsproxy.io.”
“Next, you may encounter CORS errors…prefix this “https://corsproxy.io?” in front of your image url.”
“Even if the server does not cooperate, you can use a CORS proxy like corsproxy.io to fetch arbitrary resources off the Internet” Professor, Dublin City University
Isolated and Secure Execution
Every proxy request runs inside its own isolated, ephemeral container — spun up on demand and gone the moment it completes.
Each request executes in a dedicated, short-lived container. There’s no shared memory, no persistent state, and no way for one request to affect another.
No shared state between requests
Container torn down immediately after each request
All traffic encrypted in transit
Every request executes in its own sandboxed environment with no access to other requests’ data.
Containers carry no memory from previous requests — your data is never cached in the execution environment.
Every connection between client, proxy, and origin is encrypted end-to-end with TLS.
Requests are handled at the edge, close to your users — not on a central server with shared resources.
