Sovereignty ties at 4.0, 0 lean either way, 6 tie: both list a US legal entity jurisdiction; Cal.com's pages state US processing with EU residency only on contact, and we found no public information on EU hosting for Calendly.

Read this comparison as one judge. Each weighs the same scores by what they care about.
The Salon Owner
Owns two hair and beauty salons with eleven stylists and a Saturday that is booked out by Wednesday. Wants every service with its own duration and price on one booking page, clients who pick their stylist, a deposit for colour appointments, a fee when someone does not show, and a monthly bill that does not grow with every chair.

Calendly
Criterion by criterion
Booking page & client experience
Cal.com
Every event type carries its own title, description, duration and a price you set, plus custom booking questions, four embed options for my salon's site, and confirmations that let a client reschedule without calling — that is the services-on-one-page setup I want. Embeds are stated responsive and mobile-ready, branding removal comes with the Teams plan, and seat-based group bookings appear among the webhook events. We found no public information on booking pages in several languages, automatic time-zone handling, or a step-by-step flow where the client chooses service, stylist and location.
Calendly
Each service can carry its own name, duration and host, with booking-form questions like a phone field, secret services hidden from the public page, a preview before publishing, an embed with custom colors for my salon site, and cancel/reschedule links on the confirmations. Guests up to ten can be added, the page language can be changed and time zones are detected automatically, but I found no public information on seat limits for group classes, branding without the vendor's logo, or an accessibility statement for the booking pages.
Calendar sync & availability rules
Cal.com
Named connections to Google Calendar, Microsoft Outlook, Apple/CalDAV and Zoho pull event details and free/busy data, and the availability tooling is built to avoid double bookings, with working hours, date overrides for holidays or a day off, buffers, minimum notice, booking horizon and daily, weekly or monthly limits all documented. We found no public information on resources such as chairs or rooms that must also be free, which is the piece a two-salon week needs most.
Calendly
Busy times are read from Google, Outlook and Office 365 calendars with meetings written back, and paid plans let each stylist connect up to six calendars; buffers, minimum notice, booking date ranges and meeting limits per day, week or month are all documented. I found no public information on iCloud or CalDAV, holiday closures, or rooms and equipment that must also be free, and connected calendars apply to all event types rather than being assignable per service.
Team, staff & location scheduling
Cal.com
Teams get shared availability or per-host schedules, round-robin distribution described as based on availability, weights and priority rules, collective events for several people at once, routing forms that send a booking down the right route in evaluation order, and owner or team-admin control over team event types; the Organizations plan adds SAML single sign-on and SCIM provisioning with role-based permissions. We found no public information on several locations each with their own staff or reporting per stylist.
Calendly
Round robin with a configurable distribution method, per-host schedules and locations, collective events, routing forms that qualify and direct visitors, and owners, admins and group admins with defined edit rights cover my eleven chairs, and a CSV download shows how meetings were distributed among the team. The enterprise pages also show single sign-on with SAML, SCIM provisioning, Salesforce routing based on record ownership, centrally managed event types and an audit log, though I found no public information on whether a customer can pick a specific stylist by name on the page.
Reminders, payments & no-show protection
Cal.com
Automated workflows send email, SMS and WhatsApp messages at minutes, hours or days before the appointment, with follow-ups after it ends, and payment is collected before the meeting through Stripe with a charge amount, currency and payment option set per event type — enough to stand a colour deposit on. But we found no public information on a cancellation deadline the system enforces, no-show or late-cancellation fees, or a waiting list that refills a cancelled chair.
Calendly
Email and text reminders before and after events are documented for every plan with customisable subjects and bodies from Standard up, payments run through Stripe and PayPal, and the homepage shows a 'Client pays $150 deposit upfront' example alongside follow-up features — so the colour deposit is covered. The help centre states the cancellation policy is displayed but does not restrict cancellations or reschedules, and I found no public information on no-show or late-cancellation fees, card-on-file charges, or a waiting list that refills a freed slot, which is exactly the half I need for a Saturday that is gone by Wednesday.
Integrations, API & data export
Cal.com
There is a documented v2 API with OAuth scopes and team-level endpoints, webhooks with 31 trigger types including booking created, paid, rescheduled and no-show events, native Salesforce, HubSpot and Pipedrive connections in a 100-plus app directory with Zapier, embeddable atoms as an SDK, and an open-source self-hostable version under an MIT licence. Export is self-serve at any time with at least 30 days after termination and deletion covering subprocessors; we found no public information on published API rate limits or a documented export format.
Calendly
A documented API with real-time webhooks covers scheduled events, contacts, invitee details including custom question answers, with native connections to HubSpot, Salesforce, Microsoft Dynamics, Marketo, Pardot, Mailchimp and Zapier, plus Google Analytics and Meta Pixel. CSV exports exist for routing responses and round robin statistics, but I found no public information on published API rate limits, an integrations directory, a self-hosting or migration path, or a documented full-account export of my client records.
European sovereignty
Cal.com
The contracting party is Cal.com, Inc., a Delaware corporation, and the privacy policy states data is processed in the United States with some subprocessors elsewhere, so the chain is American end to end; EU data residency is only offered on contact. It does publish a data processing agreement for every account, a subprocessor list at its Trust Center covering hosting, email, SMS, video and payments with prior notice and objection rights, plus ISO 27001 and SOC 2 Type II certifications and an EU representative in Germany — good disclosure, wrong hemisphere.
Calendly
The contract is with Calendly, LLC of Buford, Georgia, processing occurs in the United States and other jurisdictions, and the published subprocessor list is almost entirely US-based, including Twilio for SMS and OpenAI for meeting summaries and SMS compliance. A processor agreement, SCCs and Data Privacy Framework participation, ISO 27001, SOC 2 and PCI certifications, and Berlin and London representatives are stated, but no EU hosting option or EU contracting entity appears anywhere, so the whole chain holding who books when sits with US providers.
Pricing transparency
Cal.com
Tiers are public — a free individual plan, Teams at "$12 per user/month" billed yearly with a 14-day trial, Organizations at "$28 per user/month" billed yearly, and Enterprise as custom pricing on request — with the scaling unit (users), each tier's features, no card needed to sign up, automatic renewal and VAT-exclusive fees stated. But per-user pricing is exactly the bill that grows with every chair I add, and we found no public information on SMS credit costs, payment processing fees, or the monthly price behind the stated yearly figures.
Calendly
Prices are public per seat — Standard at $10 /seat/mo and Teams at $16 /seat/mo, with monthly or yearly billing and a stated yearly saving of up to 20 percent — and the terms spell out month-to-month or twelve-month terms, billing in advance, that I pay the taxes, and that fees are non-refundable. What I cannot compute from the public pages is the Enterprise and Teams Plus tiers, the cost of SMS credits, and the price of the Notetaker and Callie add-on, and free accounts inactive over six months may be terminated.
