A simple Webserver with GUI for Windows. You navigate to the folder you want to serve and just click "Start".

I use it all the time when I need to serve up some data in JSON for example. I can specify IP and Port to bind to, it has directory listing enabled and it always sets the headers "Access-Control-Allow-Headers: " and "Access-Control-Allow-Origin: " for easier quick testing.

I just threw together some components in Delphi. ;)
