I can connect to localhost on Safari Version 14.0.1 Make sure you also load index.htm from the same host! (localhost) so you need a little web server in your app that serves that file. One problem is however that there is no easy way to get Safari to run in chromeless/app mode (without browser/url bar etc), which you can do in most other browsers using --app=url flag
