Cool! I see you made the URL an argument to the script, it's a good idea because OP's script only works locally as it serves the website at localhost, so you can't access it from another client on the network.

My script is just using OPs script to serve it. So it works all the same.

Hello @vwrs, if you change "localhost" --> "0.0.0.0", the webserver can run from other network clients (e.g., smartphones) 😃
