This plugin provides an instance of the cors-anywhere proxy, hosted on homebridge. This means, that through it, every response has the access-control-allow-origin: * header.
You have a local web application which needs access to url with non-matching CORS? Then this is the plugin for you.
It is built entirely on top of the cors-anywhere npm package. Use their docs to find out how to use this plugin properly:

The proxy is listening at (your-homebridge-ip):5654
example: http://homebridge.local:5654/http://homebridge.local/api/auth/settings
