Frequently asked questions

What people usually want to know before signing up for Cal.com.

Can I self-host Cal.com?

Yes — Docker install, full feature set.

Cal.com vs. Calendly?

Cal.com for developers + privacy; Calendly for ecosystem + recognition.

Does it work with multiple calendars at once?

Yes — connect multiple Google/Outlook calendars for conflict checking across work, personal and side projects.

Can I collect intake data in the booking form?

Yes — custom fields, conditional logic and payment collection are standard on the paid tier.

How does routing by rep or lead score work?

Round-robin and weighted routing are standard. Routing by lead score needs a CRM webhook — supported but takes 30 minutes to wire up.
