CORSmirror

A lightweight CORS proxy API that fetches any URL and returns it with CORS headers enabled.

PlatformWebfree

CORSmirror is a small RESTful API, hosted on Cloudflare, that proxies requests to any URL and returns the response with CORS headers enabled. It's meant for frontend developers who need to fetch data from a third-party URL that doesn't itself support cross-origin requests. Usage is a plain HTTP call with the target URL as a query parameter, with no signup required.
