I am a Calendly User, and I love it. but in the free plan, it's just 1 event type, and everything else you want to do is paid. I tried SchedulingKit, and I believe it can replace Calendly. I will be able to save this monthly expense. I can have unlimited book types, my own branding, 10 connections per user, and multiple teammates in one code.

I have purchased tier 3, and it has everything I need.

I went ahead, created a couple of event types, invited teams, created collective and round-robin event types, and embedded the scheduling link for the collective event type on my website. Everything went well and smoothly. Faced a couple of issues with availability and setting up the domain but was able to manage with the help of the team.
So for me, it's a no-brainer. And if you are looking for a good scheduling solution that works and you want to save that monthly cost, I would say, this is your deal. Get it.
