Read this comparison as one judge. Each weighs the same scores by what they care about.
The Data Protection Officer
Signs off booking tools for a group of medical and legal practices, where an appointment alone reveals who is a patient or a client. Wants the contracting entity and hosting named, every subprocessor listed down to the SMS gateway and the email service, calendar access limited to what booking needs, and bookings and customer records that can be exported and deleted on request.

This judge's pick
Calendly
Criterion by criterion
Booking page & client experience
Cal.com
Event types carry their own title, duration and location, custom booking questions and email verification for bookers are configurable, a short custom booking link is offered, and four embed options put booking on the practice's own site, stated to be mobile-optimised and white-labellable, with confirmations that let bookers reschedule with ease. Dynamic group links combine several people into one link. We found no public information on booking pages in several languages, seat limits for group classes, or an accessibility statement for the booking flow.
Calendly
A booking page is documented with one-on-one, multi-host and group event types each carrying a name, duration, location and host, custom questions such as a phone-number field, a website embed with customisable colours, and cancel and reschedule links in the invitation emails. Automatic time-zone detection for host and invitee and an event-language option are described; we found no public information on seat limits for group events, branding without the vendor's logo, or an accessibility statement for the booking pages.
Calendar sync & availability rules
Cal.com
Calendar connections are named — Google, Microsoft Outlook, Apple/CalDAV and Zoho — with the privacy page stating exactly which fields are read, including free/busy data, which is the scope limitation I look for; availability rules run deep with buffers, minimum notice, booking frequency and horizon limits, and date overrides that mark a day unavailable. The captured pages do not state that sync works in both directions or that several calendars per person are checked together for conflicts, and we found no public information on booking rooms or equipment alongside the person.
Calendly
Connected Google, Outlook and Exchange calendars are checked for busy times and new meetings are written back into them, with up to six connected calendars per user on paid plans, preferred meeting hours, buffers, minimum scheduling notice, booking date ranges, and meeting limits per day, week or month. We found no public information on iCloud or CalDAV connections, holiday and absence schedules, or rooms and equipment that must also be free alongside the person.
Team, staff & location scheduling
Cal.com
Team scheduling is close to complete for a multi-practitioner group: round-robin by availability, weights and priority rules, collective and managed event types, routing forms evaluated in order, team admin and owner roles enforced down to the API permissions, and SAML SSO with SCIM provisioning on the organizations tier. We found no public information on several locations with their own staff, audit logs of changes, or fairness reporting on how bookings are distributed.
Calendly
Round-robin events assign the next available host with a configurable distribution method, per-host schedules and per-host locations, collective events bring several people together, and routing forms steer visitors by their answers and even by Salesforce ownership of an account, contact, lead or opportunity. Distinct owner, admin and group-admin edit rights, single sign-on with SAML and SCIM provisioning, centrally managed event types, a real-time audit log, and a downloadable report of event distribution across team members are all documented.
Reminders, payments & no-show protection
Cal.com
Reminders are strong: workflows send email, SMS or WhatsApp at configurable minutes, hours or days before an event, with custom templates, follow-up messages after the call, and payment at booking through Stripe or PayPal with per-event charge amounts. No-show detection exists as event triggers, but we found no public information on enforced cancellation deadlines, no-show or late-cancellation fees, deposits, or a waiting list that refills cancelled slots.
Calendly
Email and text reminders before and after events are available to all users with customisable subject and body from the Standard plan, and payments at booking run through Stripe and PayPal, including a documented example of a client paying $150 deposit upfront. The help centre states the cancellation policy is displayed but does not restrict cancellations or reschedules; we found no public information on waiting lists, no-show or late-cancellation fees, or card-on-file charges.
Integrations, API & data export
Cal.com
A documented v2 API with Bearer-key or OAuth authentication, webhooks with thirty-one trigger types and versioned payloads, Zoom, Teams and Google Meet links created automatically, native two-way HubSpot and Salesforce sync, Zapier and an app store of a hundred-plus apps give the connections a practice needs. Bookings and customer data are exportable at any time self-serve, deletion is stated to reach subprocessors, and self-hosting under an MIT-licensed open-source option plus embeddable components are documented. We found no public information on published API rate limits or the format of the account export.
Calendly
A documented public API with OAuth and personal-access-token authentication covers scheduled events, invitee details including custom question answers, contacts, routing forms and a data-compliance area, with real-time webhooks, signing keys and developer documentation; native HubSpot and Salesforce connections and Zapier automation are named. The data processing agreement promises return or secure destruction of personal data on request or termination and account deletion is effective immediately, which is the export and deletion footing I look for; we found no public information on published API rate limits or a bulk export of the complete booking and customer records.
European sovereignty
Cal.com
The contracting entity is named — Cal.com, Inc., a Delaware corporation — and the pages state plainly that data is processed in the United States, with EU residency only on request; a data processing agreement binds every account, transfers rest on the Data Privacy Framework and Standard Contractual Clauses under Irish law, and a subprocessor list covering hosting, email, SMS, payments, video and analytics is published with prior notice and objection rights on any change. For the medical and legal practices I sign off, that transparency is real but the chain runs through US providers by default, and we found no public information naming the hosting infrastructure or the individual SMS gateway and email delivery services behind the published categories.
Calendly
A data processing agreement with Standard Contractual Clauses, an Irish Data Protection Commission reference and annual audit reports is published, and the subprocessor list names each provider down to Twilio as the SMS gateway, with locations and privacy contacts — exactly the disclosure depth I require. The contracting entity is Calendly LLC of Buford, Georgia, processing occurs in the United States and other jurisdictions with no EU hosting option offered, and almost every listed subprocessor runs from the USA; the same agreement also prohibits submitting special-category data, which my medical and legal practices cannot accept where a booking itself reveals who is a patient or a client.
Pricing transparency
Cal.com
Prices are public with their scaling unit — free forever for one user, Teams at $12 per user/month and Organizations at $28 per user/month on yearly billing with "Save 25%" stated, a 14-day free trial, and no credit card at signup — and the tax treatment and non-refundable default are stated in the terms. Enterprise is custom via a sales call, only yearly figures are shown, and we found no public information on SMS credit costs, monthly-billing prices or a minimum term, so a practice cannot compute its full annual cost from public pages alone.
Calendly
Public tiers run from an always-free plan to Standard at $10 /seat/mo and Teams at $16 /seat/mo billed yearly, with monthly and yearly billing both shown, the customer responsible for taxes, and month-to-month or twelve-month terms stated. We found no public information on the price of SMS credits, payment processing fees, or the Enterprise tier, so a practice cannot compute its full annual cost from public pages alone.
