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.

The Independent Consultant
Sells coaching sessions and workshop days on her own and books clients from Germany, Austria and Switzerland. Wants a booking page that looks like her own website, payment taken when the session is booked, a buffer after every call, her private calendar respected, reminders she never has to send herself, and a price that makes sense for one person.

This judge's pick
Criterion by criterion
Booking page & client experience
Calendly
The booking page is well documented: event types with their own name, duration, location and hosts, custom booking questions with a phone field, guests up to ten, an embed for my website with customizable colors, and cancel and reschedule links in the invitations and reminders. Group events, language switching per event type and automatic time-zone detection for both sides push it further, though I found no public information on seat limits for group events, removing the Calendly branding, or an accessibility statement for the booking pages.
zeeg
There is a booking page I can embed on my own website, custom intake questions at booking, and workflows that carry a reschedule link; group sessions, webinars and on-site appointments are supported and time zones are handled. What keeps me from going higher: I found no public information on booking-page languages, seat limits for group events, branding without the vendor's logo, or an accessibility statement.
Calendar sync & availability rules
Calendly
My two must-haves are documented: built-in buffers and breaks to protect time after a call, and connected Google, Outlook and Office calendars checked for busy times so my private calendar is respected, alongside minimum scheduling notice, booking date ranges and daily, weekly or monthly meeting limits. Paid plans connect up to six calendars, but I found no public information on iCloud or CalDAV, holidays and absences, or resources, and the help pages state connected calendars cannot be assigned to individual event types.
zeeg
Two-way sync covers Google, Microsoft, Exchange, iCloud and CalDAV, with booked appointments written into my calendar and an event I decline cancelling in Zeeg — my private calendar stays respected. I can pick exactly which calendars are checked for conflicts, set buffer times, block hours, out-of-office periods and public holidays; I found no public information on minimum notice, booking windows, or rooms and equipment as bookable resources.
Team, staff & location scheduling
Calendly
Far more than I need as one person, but the documentation is unusually complete: round-robin with a configurable distribution method and per-host schedules and locations, collective events, routing forms that can route on Salesforce ownership, centrally managed event types and team templates, plus SSO with SAML and SCIM provisioning, a real-time audit log and round-robin distribution statistics downloadable as a CSV. The only soft spot is that weighted round-robin and locations with their own dedicated staff are not clearly spelled out.
zeeg
Round-robin with availability-maximising or equal distribution, high/medium/low priority per member, per-member meeting caps, and routing by region, language and form answers are all documented, alongside five organisation roles and two team roles with granular permissions, SSO/SCIM and an activity log. I found no public information on collective meetings that need several people at once, several locations with their own staff, or reporting per staff member.
Reminders, payments & no-show protection
Calendly
Automatic email and text reminders before and after each event, managed per event type and customizable on the Standard plan and up, plus payment at booking through Stripe or PayPal with a worked example reading "Client pays $150 deposit upfront" — that covers my essentials without me lifting a finger. But the help pages state plainly that a cancellation policy is displayed and not enforced, and I found no public information on no-show or late-cancellation fees or a waiting list that refills cancelled slots.
zeeg
Automated workflows send confirmation emails, reminders before the event, follow-ups and surveys by email and SMS to host or invitee, SMS credits are priced (10 free per month on paid plans, a bundle of 1000 SMS credits for €9.99/month net), and payment is taken at booking through Stripe or PayPal — the core of what I need as a one-woman business. Meetings can be marked as no-shows with a follow-up message including a reschedule link, but I found no public information on deposits, an enforced cancellation deadline, no-show fees or a waiting list.
Integrations, API & data export
Calendly
A documented API with OAuth and personal access tokens, real-time webhooks with a signing key across a long list of resources including scheduled events and custom question answers, plus named integrations for HubSpot, Salesforce, Marketo, Pardot, Microsoft Dynamics and Zapier — more than enough to wire bookings into my own website and tools. Routing form responses export as CSV, though I found no public information on published rate limits, an integrations directory, or a full documented export of bookings and customers.
zeeg
Video links are created automatically for Zoom, Google Meet, Microsoft Teams, Webex and Whereby, Zapier connects automation, HubSpot, Pipedrive and Salesforce integrate natively, and there is a documented developer hub with a public API and webhooks for bookings, cancellations, no-shows and routing submissions. The gap: I found no public information on an export of bookings or customer records.
European sovereignty
Calendly
Calendly is a US company and its data processing agreement states that processing occurs in the United States and other jurisdictions; a subprocessor list is published, but it names almost exclusively US providers, including Twilio for SMS and OpenAI for the AI features. Certifications including ISO 27001 and SOC 2 Type 2 are published and an EEA representative sits in Berlin, yet I found no public information on EU hosting or an EU contracting entity, so my DACH clients' booking data would run through an American chain end to end.
zeeg
Zeeg GmbH in Berlin is the contracting entity, a data processing agreement is included, and appointments, contacts and form responses sit on German servers at Telekom Deutschland's T Cloud Public — though the captured pages give different figures for the hosting region (Germany only, versus data centres in Germany and the Netherlands). The subprocessor list names locations — Brevo in Berlin for email and SMS, Twilio Ireland, ElevenLabs with EU data residency, Sentry in Germany, Paddle in the UK — with adequacy decisions and standard contractual clauses covering transfers; I found no public information on security certifications or the ownership structure.
Pricing transparency
Calendly
The tiers are public with their scaling unit: a free plan connecting one calendar, Standard at $10 /seat/mo and Teams at $16 /seat/mo billed yearly, monthly and yearly billing both offered, and month-to-month or twelve-month terms stated in the customer terms. But I found no public information on the price of SMS credits or payment processing fees, and the Enterprise tier runs on invoice billing, so as a one-person buyer I cannot compute my true first-year cost with text reminders from the public pages alone.
zeeg
Every tier is public — Starter free forever with two booking pages and unlimited events, Professional at "10 € /Monat/Nutzer", Business at "16 € /Monat/Nutzer", Scale at "30 € /Monat/Nutzer", each "jährlich abgerechnet, zzgl. MwSt." — with SMS bundles at €9.99/month (net), a 14-day trial without credit card, the 12-month annual term with six weeks' notice and the monthly no-lock-in option all stated. The Enterprise tier is individual ("Individuell Sprich mit uns"), and only the annual per-user prices are shown, so I cannot compute a monthly-billed cost from the captured pages.
