CORS Proxy: Enable Cross-Origin Resource Sharing

A CORS proxy is a service that adds CORS headers to requests to enable cross-origin resource sharing. It acts as a proxy between the client and server to enable client-side JavaScript code to access resources from other domains.

What is CORS Proxy?

A CORS (Cross-Origin Resource Sharing) proxy is a server that acts as an intermediary between a client (such as a web browser) and a server to enable cross-origin requests. CORS restricts web browsers from making requests to a different domain than the one hosting the web page, for security reasons.

A CORS proxy adds the required CORS response headers to requests and responses to enable cross-origin access. This allows the client-side code (JavaScript, etc.) hosted on one domain to access resources from a server on a different domain, bypassing the same-origin policy applied by web browsers.

Some common uses of a CORS proxy include:

  • Enabling a web application served from one domain to access a REST API served from another domain
  • Allowing web browsers to use client-side JavaScript to access APIs on other domains
  • Retrieving resources stored on other servers like images or fonts

Overall, a CORS proxy is useful for any application that needs to fetch resources cross-origin from servers that do not send the Access-Control-Allow-Origin header themselves, circumventing same-origin restrictions.

CORS Anywhere

CORS Anywhere is a Node.js reverse proxy service that adds CORS headers to requests. This allows you to access APIs from client-side code (like JavaScript in the browser) that otherwise prohibit cross-origin requests.Many APIs do not enable CORS (Cross-Origin Resource Sharing) by default. This means XMLHttpRequest and Fetch requests made...

All Origins

All Origins is a browser extension available for Chrome, Firefox, and Edge that allows developers and power users to bypass CORS (Cross-Origin Resource Sharing) restrictions when making HTTP requests from the browser. CORS is a security mechanism that prevents JavaScript code on one domain from accessing resources on another domain.The...

Whatever Origin

Whatever Origin is a privacy-focused web browser developed by Whatever Inc. It allows users to access the internet anonymously by routing traffic through multiple servers around the world to obscure the user's actual IP address and location.Some key features of Whatever Origin include:Encrypted connections to protect against surveillance and trackingSupport...

Crossorigin.me

crossorigin.me is a handy online tool that gets around the browser's same-origin policy to enable cross-origin HTTP requests. The same-origin policy prevents scripts on one site from accessing resources on another site - this is an important security feature but can sometimes get in the way of development and testing.To...
Any Origin icon

Any Origin

Any Origin is a free web proxy service that allows you to bypass CORS (Cross-Origin Resource Sharing) restrictions and access resources from any website. It works by acting as a proxy between your browser and the target server, adding the required Access-Control-Allow-Origin headers to enable cross-origin requests.CORS is a security...

Corsproxy

corsproxy is an open source proxy service designed to add CORS headers to requests. This allows client-side web applications, such as those built with JavaScript frameworks, to access APIs served from domains that do not have CORS enabled.Without CORS headers, web browsers will block JavaScript code from accessing resources on...
