Calendly scores higher on 3 of 7 criteria (Team, staff & location scheduling, Integrations, API & data export and Booking page & client experience). zeeg scores higher on 4 of 7 criteria (European sovereignty, Pricing transparency, Calendar sync & availability rules, plus 1 more). Provenance — Calendly: Rest of world; zeeg: EU-Made. Ratings are the AI panel’s opinion, formed from public evidence: how scores are made.
The benches split by criterion rather than collapsing into one verdict. Calendly is ahead on team scheduling (mean 9.2 to zeeg's 8.2; six judges lean Calendly, zero lean zeeg), on integrations and data (7.7 to 7.0; four lean Calendly) and on booking experience (6.3 to 6.0; two lean Calendly). Zeeg is ahead on calendar and availability (7.2 to 6.5; four lean zeeg), reminders and no-shows (6.3 to 6.0; two lean zeeg), pricing transparency (7.0 to 5.8; six lean zeeg) and sovereignty (7.0 to 4.0; six lean zeeg). Of the four judges with published weighted totals, the sales team lead has Calendly ahead, 7.5 to 7.2, while the consultant, the data protection officer and the skeptic have zeeg ahead. Sovereignty as it stands: Calendly's legal entity jurisdiction is US with US-default data residency; zeeg's is DE with EU-only data residency and US Cloud Act subprocessor exposure.

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.

Criterion by criterion
Booking page & client experience
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.
zeeg
A booking page can be embedded on my own website, asks custom intake questions, handles time zones and covers one-on-one, group and on-site appointments, with a reschedule link built into follow-up messages. I found no public information on clients choosing a specific stylist mid-flow, seat limits on group sessions, multi-language pages, branding or accessibility.
Calendar sync & availability rules
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.
zeeg
Google, Microsoft, Exchange, iCloud and CalDAV calendars sync both ways — booked slots land in my calendar and deleting the calendar event cancels the booking — with conflict checks across the calendars I choose, buffers, blocked hours, out-of-office and public holidays. I found no public information on rooms or chairs as resources or on sync latency.
Team, staff & location scheduling
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.
zeeg
Round-robin comes in a maximise-availability or equal-distribution mode with high, medium or low priority per member, routing assigns by territory, language or custom answers, five organisation roles plus Manager and Member exist with an admin activity log, and SSO and SCIM with Okta and Microsoft Entra are documented. I found no public information on several locations each with their own staff, or on collective bookings.
Reminders, payments & no-show protection
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.
zeeg
Workflows send confirmations, reminders and follow-ups by email and SMS to client or host, triggered before, during, after, on cancellation and on no-show, clients can pay at booking through Stripe or PayPal, and no-shows can be marked, tracked and answered with a reschedule link. I found no public information on deposits or partial prepayment, a system-enforced cancellation deadline, a no-show fee, or a waiting list that refills a freed slot — the protections my colour appointments need.
Integrations, API & data export
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.
zeeg
Video links are created automatically for Zoom, Google Meet, Teams and Webex, HubSpot, Pipedrive, Salesforce and Zapier connect natively, and a documented webhook API carries events for bookings, cancellations, no-shows and routing submissions. I found no public information on exporting my bookings and client records, or on API rate limits.
European sovereignty
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.
zeeg
The contracting entity is Zeeg GmbH in Berlin with a German register number, hosting runs on Telekom Deutschland's T Cloud, a data processing agreement is included, and the privacy policy names its subprocessors with addresses — Brevo in Berlin for email and SMS, Twilio Ireland and ElevenLabs with EU data residency, alongside US providers such as Sentry and Webflow. The captured pages give different figures for the hosting region (Germany only versus Germany and the Netherlands), and I found no public information on ISO 27001 or SOC 2 certifications.
Pricing transparency
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.
zeeg
Every self-serve tier carries a public per-user price — "10 € /Monat/Nutzer", "16 € /Monat/Nutzer", "30 € /Monat/Nutzer", each "jährlich abgerechnet, zzgl. MwSt." — with a permanently free Starter plan, round-robin gated at Business, an SMS bundle of 1000 credits for "€9.99/month (net)", and monthly cancellation or a twelve-month annual term with six weeks' notice. Per-user pricing is exactly what I do not want with eleven chairs, the Enterprise tier is individually quoted, the monthly-billing rates are not in the captured pages, and I found no public information on payment processing fees.
