warp cors

Enable CORS headers on any request and avoid same-origin policy issues.


Prepend your request url with https://warp-co.rs/ to proxy your request and add CORS headers to the response. For example;


The proxy will respond to pre-flight requests allowing all methods and headers. Any other requests will be forwarded to the destination and the proxy will modify the response to allow any origin and expose all headers found in the response.

The protocol of the url you are requesting must be either http or https. Cookies are not supported, Cookie and Set-Cookie headers are stripped from the request and the proxied response respectively.

If you find this service useful you can support me on Ko-fi or sponsor me through GitHub Sponsors.


Basic access logs are kept for requests to the service in order to prevent abuse. This includes the IP address of the client, and the proxied url being requested. No other information is stored.

The source code behind this service is open-source and can be reviewed. However, there is no guarantee that this matches what is running on this server. Please keep this in mind when using the service.

You should never send any requests containing sensitive information.
