Excellent really

Fast and efficient service.

Merci au service technique pour avoir résolu mon problème

Great responses. Quick.

Milos P., the main contact, is super helpful. We use AI agents to make appointments for our clients, and when our clients ask, 'Hey, can you use Calendly?' ... No, but why???? ...Because we have tested it for 6 months, over and over again, and like you, we hate repeating ourselves. ENJOY! Cal Dot Com :-)

Solved my problem. Thanks!! great service

All of my questions answered, requests actioned, confusion explained. I did have to wait for an initial response but that's only because we are located in completely different time zones. When support were active, response was extremely quick.

What sets Cal.com apart is that it's actually open. I integrated my product with their booking API (v2) and it was clean, well-documented, and simply worked — live availability and bookings behaved exactly as expected. Even better, they're the rare scheduling platform with a real, open app store: I was able to contribute my own integration as a pull request, and once a maintainer picked it up the review was fast and constructive. The open-source ethos isn't just marketing — you can read the code, build on it, and add to it. If you want scheduling you can extend rather than just rent, it's a great choice.
