This project is a clone of cors-server. See the readme there for more on the implementation instructions. The purpose of this server is to whitelist URLs for users that could not deploy their own server on a per-request basis. It is recommended that users try all available options before making a request. It should only be for very low traffic sites so that usage limits are not reached.
Just on Firebase for now.
