As a previous occasional user of Calendly I couldn't justify the cost of the ongoing monthly subscription for a simpler version of it which is set up and forget. Cal.com seems built with a better plug-in foundations and it's free for individuals with open-source code and open development process. What's not to like?

I am still scratching my head over the same thought. The title is literally the name of the app. What's the magic formula here?

HN likes open source things. The original submission title said "open source" but it has since been changed.

Email questions like that in.
