Enterprise Software: Cal.com hosting
Cal.com is the open-source alternative to Calendly – a scheduling system with which customers and partners book free slots themselves. We host Cal.com in a GDPR-compliant way on European infrastructure, connect it to your calendars and tools and keep it running. This way you automate scheduling without customer data ending up with a US provider.
Challenges you'll recognise
- Coordinating appointments with customers eats up emails and time, and double bookings still happen.
- Your current booking tool sends customer data through a US provider, which is unclean for data protection.
- Per-user fees for the booking tool add up the more employees offer appointments.
Scheduling automated
Cal.com shows your free times and lets customers book themselves – including confirmations, reminders and buffer times. The back-and-forth by email disappears, and thanks to automatic calendar synchronisation there are no more double bookings.
Calendar & tool integration
Cal.com connects with common calendars and video tools and can be embedded in workflows. We set up the integrations so appointments land automatically in the right calendars and meetings are created without extra steps.
Self-hosted operation
Self-hosted, Cal.com runs on your European infrastructure, so your customers' appointment and contact data stays under your control. We handle installation, configuration and ongoing operation.
Data protection & GDPR
Booking data contains personal information. With self-hosted Cal.com this stays on European servers instead of running through a US service – a clear data-protection advantage.
Cal.com in action
Scheduling under your own brand – availability, teams and workflows.
Good to know
Less scheduling chaos
Self-booking with calendar sync eliminates the classic back-and-forth and double bookings – saving measurable time in sales and consulting.
Booking data is personal
Names, email addresses and appointments are personal data. Self-hosting keeps them on European infrastructure instead of with a US service.
In your own brand presence
Embedded booking flows keep the customer on your site instead of on a third-party platform – better for trust and brand image.
