Cronofy has built a best in class sync engine that keeps everything up to date in real-time. No double-bookings and no time spent rescheduling meetings.


You can decide to only access free/ busy information if you don't want to access, protect and encrypt calendar data.


In the time it would take you to build something that works with one calendar service, you can build something that works with five.

"Integrating with Cronofy was really straightforward. Their documentation and support are first-class. We were able to quickly and easily integrate calendar availability into our call scheduling feature without having to worry about setting up several disparate calendar service integrations."

"Writing custom integrations for multiple calendar APIs can take months of work with all the configuration and testing. Cronofy’s APIs simplified that process in a fraction of the time. We only have to worry about the actual implementation of our Booking Feature instead of worrying about the overhead of the integration."

"Cronofy's Calendar API manages to be both very powerful and easy to work with. We were able to build two-way calendar sync in our application in a few weeks. The implementation itself was straightforward and their support team was quick to help with any questions we had."
