Comments about Cal.com as an Alternative to Calendly
Not dependent on JavaScript and open source. Honestly, more and more businesses are locking down JS to only trusted sites or ones they use internally. Calendly depends on it, and I had some people not be able to use it because of this. Cal provides you the same kind of functionality and is much easier to manager. Calendly does have some added functionality but as I found out
Cal.com (formerly Calendly) is the BEST alternative to Calendso that I've tried, and offers additional intergrations. Their free tier is also a lot more generous, and if you want to self-host, there are simple ways of doing so via Railway.
More features, pretty, and OSS.
