Is Cal.com really free?

Cal.com is open-source and can be self-hosted for free. However, for organizations that prefer to avoid the maintenance, security, and infrastructure costs of self-hosting, they offer paid cloud-based subscription plans.

Can I white-label Calendly?

Calendly offers limited branding customization, such as adding logos and adjusting colors, but it is not a true white-label solution. Users cannot remove all Calendly branding or host the platform on their own infrastructure.

Which platform is better for data privacy?

Cal.com is generally preferred for strict data privacy requirements because it allows for self-hosting, meaning you keep your scheduling data on your own servers rather than a third-party cloud provider.

Evaluate your integration stack: List the specific tools (CRM, Video Conferencing, Payment Processors) that must connect to your scheduler to ensure compatibility.
Run a pilot: Use the free tier of both platforms with a small group of users to test the booking flow and administrative overhead.
Calculate the total cost of ownership (TCO): Include the time cost of maintaining a self-hosted instance if choosing Cal.com versus the subscription fees for Calendly.
