This location information is pulled from the Cloudflare Geolocation API. It uses a data base of IP addresses to estimate the location of the visitor.

To access the API, a cloudflare worker is running and accepting GET requests at https://jak.onl/geo which returns the raw JSON. I parse that JSON data and only display the most interesting information.

None of this information is stored on the server.

This is my first exploration of the Cloudflare worker serverless computing platform and it was a lot of fun.
