FYI, Cal[1] is an Open Source[2] with a SaaS generous offering whose free version is adequate for most use case. No affiliation but a happy customer since its early days. It was, once, not able to compare with Calendly but has come a long way in a good way.

+1 to use what you know comments, also check out https://github.com/calcom/cal.com tech stack(next+prisma/trpc). If you have literally zero frontend experience though, vue 3 was very beginner friendly for me
There is already Cal.com (formerly Calendso) [0] which is a more matured product. I do personally feel though Calcom's codebase is unnecessarily complex and bug-prone.

Nice to see new alternatives in this space. It would have been nicer to see a comparison with Calcom and some self-hosting guidelines.

The co-founders are nice people and I have a years worth of the premium version. Unfortunately, too buggy and people end up booking at the wrong hour, multiple-events gets reset when I change time-slots in another.

I haven't found something as simple as Calendly -- that just works. A commenter here once commented about a different alternative but that got bought out and shuttered. I'm still on the final look-out till end of this month (FEB), else going back to the Calendly subscription.
