Open source scheduling infrastructure for hiring marketplaces

Cal is a white-label friendly, open source scheduling infrastructure product that takes the stress out of coordinating agendas and finding a time to meet.

Cal does this by offering advanced customization, and making it easy for people to integrate their already existing calendars with our product.

Hiring marketplaces can use Cal in order to support round-robin scheduling, collective events, dynamic links, recurring bookings, multiple custom availability schedules, and single-use links.

Our infrastructure makes it easy to offer appointments in person, over the phone, and via sync chat. Cal also comes with an app store that facilitates a whole host of video conferencing solutions. 

Cal is for everyone who prioritizes customization and wants to ensure that their brand remains first and foremost in the minds and hearts of their audience.
