European alternatives to Calendly.

Calendly is the default scheduling tool for a generation of consultants, founders, and customer success teams — and a US-incorporated product, hosted on US infrastructure, with sub-processors based in the United States that fall under CLOUD Act jurisdiction. For a German procurement team writing a Schrems II transfer impact assessment, or any EU buyer running compliance review on customer-facing booking pages, that ownership and hosting profile is what prompts buyers to evaluate alternatives.

This page maps the five European calendar-booking alternatives we have verified against Calendly on the criteria a buyer actually cares about: who legally owns the company, where the data physically sits, which sub-processors handle calendar metadata and notifications, and whether the platform holds a recognised European compliance framework (ISO 27001, BSI C5, EUCS, SecNumCloud). The compliance score is editorial, never paid, and every row is sourced to the vendor's public DPA. We re-verify quarterly.

If you only have ten minutes: Doodle wins on the pure compliance score (Swiss, 5/5, no CLOUD Act jurisdiction over Swiss federal data), Cronofy is the best fit for enterprise integration depth (UK, 4/5, API-first), and SuperSaaS is the lowest-friction migration UX for solo consultants and small teams at €8/month.

What you keep when you switch from Calendly to a European booking platform:

• Two-way Google Calendar and Microsoft 365 sync. Every alternative here supports both natively.
• Custom booking page URL via CNAME on your own domain (Doodle, Cronofy, SuperSaaS, and Reservio all support this).
• Email and SMS reminders with configurable timing.
• Webhook events for booking-created / cancelled / rescheduled.

What you give up:

• The Calendly-branded short URL (calendly.com/your-handle). Use your own domain instead.
• Round-robin and collective scheduling that "just works" out of the box. These features exist on Cronofy and SuperSaaS but are configured rather than checkbox-toggled.
• Calendly's most polished part of the product, the booking widget design system. European alternatives ship 3–10 templates; you customise via CSS rather than a visual editor on most.
• A handful of enterprise integrations (Salesforce native, Pipedrive native, HubSpot native), replaced with Zapier hops on the European alternatives, except Cronofy which has a native HubSpot connector.

A practical five-step migration plan most European booking platforms will accept.

1. Export your event types from Calendly. Calendly does not offer a clean CSV export of event types, but you can capture each event type's name, duration, buffer time, available hours, and required questions by hand. Most teams have fewer than 10 event types. Take a screenshot of each event type's settings page before migration as a reference. Booked events are exported separately via Account → Settings → Data Export.
2. Set up your own booking subdomain before the cutover. Add a CNAME record like book.yourcompany.com pointing to your new vendor's booking host. This means visitors hitting your own URL never see the brand change, only the booking widget. Doodle, Cronofy, and SuperSaaS all support custom subdomains on paid plans.
3. Recreate your event types in the new tool. Most European alternatives have a clean event-type creator. Replicate name, duration, buffer time, and availability windows from your reference screenshots. Test bookings end-to-end before sending the cutover email.
4. Update calendar invite descriptions. Calendly puts a specific footer in calendar invites ("Powered by Calendly"). The new vendor will put its own. If you have a long-standing template that internal teams expect to see, copy the exact body text into the new vendor's invite template before cutover.
5. Keep Calendly active for two weeks after migration. Anyone with a saved Calendly booking link in their browser history or a past calendar invite will hit your old URL. Set the Calendly event types to "off" but do not delete the account. Incoming clicks will see a clean "this booking page has moved, please use book.yourcompany.com" message, which is far better than a 404.
