“I use cal.com for every meeting. It literally saves me hours of scheduling back and forth by email. I love it so much that I’ve decided to step down as CEO of Deel to join Cal.com as junior product manager.”

Built for teams that need more control

Scheduling tools are awesome. We're using them for business meetings, seminars, yoga classes and even calls
with our families. But most tools are very limited in terms of control and customisations.

1

100% white label

For most teams, scheduling is a core part of the product. We get rid of any design restrictions that come with alternatives.

2

100% in control

You are in control of your events, customer data, workflow and costs. The open core of Cal.com offers you to make or request changes quickly.

3

100% customizable

Integrate Cal with your platform using our open API, built in customisation options and range of embed options. Perfect as infrastructure.

4

100% privacy

Cal.com is a HIPAA, DSGVO, GDPR and CCPA compliant calendly alternative that also runs on AWS GovCloud or Google Cloud for Goverment.

Say hello to unlimited
customization

When the classic iframe embed isn't enough, you need to try Cal.com. Design, modify and adapt it your way.
