Cal.com
Open-source scheduling that works the way you do
Overview
Cal.com is an open-source scheduling platform that gives businesses complete control over their booking experience. Unlike Calendly, Cal.com is fully self-hostable and offers deeper customisation without the premium price tag.
The AI-powered routing feature is a genuine differentiator for teams — it automatically assigns incoming bookings to the right team member based on skills, availability, location or any custom criteria you define.
For freelancers, agencies and businesses relying heavily on client calls and meetings, Cal.com removes friction from the booking process and integrates deeply with existing tools.
Cal.com is the best scheduling tool for businesses that want more than Calendly offers without paying enterprise prices. The AI routing alone is worth the switch for any team handling multiple booking types.
