I am working on an analytics tool where you will just have to make a GET request on a specific URL and I will store that Event for you.

For example If you make a request on https://mydomain.com/<your-username>/<event-name>?userid=<us...

I will store this event and show you analytics using beautiful charts.

It will work for all framework which give option to make GET request and no need to set up BIG-G analytics packages.
