Isn't cal.com open source already?

Show HN is more about showing and discussing something someone has made than an inquiry into the existence of things like the thing being showhn.

It never stops people from commenting “why didn’t you use X obscure technology I made?” unfortunately.

It’s a valid question though; I’m also curious what the motivation was here given Cal.com is also open source hmmm

Yes, but the difference isn't purely that this one is open source. It's also way cheaper (in terms of both money and also effort) to host because you can do as the demo does and use the free Google Apps Script for your backend and any of the free static web hosts for your frontend.
