As of 29 Oct 2026, the panel rates Calendly 3.5/5 and zeeg 3.5/5 in Appointment Scheduling. Weighted by what each judge cares about, 1 of the 6 judges picks Calendly and 5 pick zeeg. 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.

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.

Criterion by criterion
Booking page & client experience
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.
zeeg
The vendor documents a shareable booking page that can be embedded on the business's own website, with custom intake forms and questionnaires at booking, and event formats spanning one-on-one, group sessions, webinars and on-site appointments; invitees evidently reschedule or cancel on their own, since the vendor's study counts both behaviours. We found no public information on booking-page languages, seat limits for group formats, branding without the vendor's logo, or an accessibility statement.
Calendar sync & availability rules
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.
zeeg
Two-way synchronisation is documented for Google, Microsoft, Exchange, iCloud and CalDAV: booked events are written back, declining or deleting an event in the calendar cancels it in the product, and the specific calendars checked for conflicts are selectable per person. Availability rules cover general hours with out-of-office and public holidays, buffers, blocked hours, limits per appointment type and a cap on meetings per team member. We found no public information on rooms or equipment that must also be free alongside the person.
Team, staff & location scheduling
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.
zeeg
Round-robin with a choice of maximum-availability or even-spread modes, per-member high, medium and low priorities, and routing forms assigning bookings by region, language or custom criteria are documented, alongside five organisation roles plus Manager and Member team roles, SSO and SCIM provisioning including role assignment via Microsoft Entra ID, and an activity log for Owner and Admin. We found no public information on collective bookings requiring several people at once, or per-location staff structures.
Reminders, payments & no-show protection
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.
zeeg
Workflows send confirmations, timed reminders and follow-ups by email or SMS to host or invitee, including a dedicated no-show follow-up with a reschedule link, and the product tracks no-show rates, attendance trends and per-contact no-show history. Payment at booking through PayPal or Stripe is documented and SMS credits are priced. We found no public information on deposits, enforced cancellation deadlines, no-show or late-cancellation fees, or waiting lists.
Integrations, API & data 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.
zeeg
A public API with Bearer-token authentication and webhooks for scheduling, cancellation, withdrawal, no-show and routing-form events is documented, alongside native CRM connections to HubSpot, Pipedrive and Salesforce, Zapier automation, and automatic video links for Zoom, Google Meet, Teams and Webex. Booking-form answers are stored as HubSpot contact properties, which moves data out, but we found no public information on a self-service export of bookings and customer records.
European sovereignty
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.
zeeg
The contracting entity is Zeeg GmbH of Berlin with court registry and VAT number, hosting is named on Telekom Deutschland's T Cloud Public infrastructure, and the published privacy policy lists the chain down to the SMS and email gateway — Brevo in Berlin — plus Twilio Ireland and ElevenLabs under EU data residency for the phone agent, Paddle in the UK as merchant of record, Sentry and Webflow, with a processor agreement included, a data protection officer named, and calendar access limited to read and event scopes that check only duration and busy status. The captured pages give different figures for the hosting region — the terms state exclusively Germany, the privacy policy Germany and the Netherlands — and we found no public information on security certifications, on the ownership structure, or on an export of bookings and customer records, though account deletion on request is stated.
Pricing transparency
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.
zeeg
Four tiers are priced per user with VAT treatment stated — Professional at 10 €, Business at 16 €, Scale at 30 €, each "jährlich abgerechnet, zzgl. MwSt." — and tier contents, SMS pricing (1000 credits for €9.99/month net, 10 free monthly on any paid plan), the permanent free tier, the trial without credit card and the term rules including the twelve-month annual term with six weeks' notice are all public. The Enterprise tier is priced "Individuell" only, monthly-billing prices are not published separately beyond an annual saving of "bis zu 25%", and we found no public information on payment-processing fees for client payments.
