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 Skeptic
Has seen "free forever" booking pages that put the vendor's logo in front of every client, SMS reminders that turn out to be credits sold separately, round-robin and payments locked in the top tier, and calendar sync that reads far more than free and busy. Reads the price list for what scales per seat, the subprocessor list for where the reminders are sent from, and asks how the bookings get out again.

Criterion by criterion
Booking page & client experience
Calendly
The booking pages carry one-on-one, multi-host and group event types with their own duration and location, custom questions such as a phone field and a split name field, embeddable on the business's site with customizable colors, and confirmation emails include cancel and reschedule links invitees can use themselves. It stays short of the top anchors: we found no public information on seat limits for group bookings, removal of the vendor's branding, an accessibility statement, or multi-step selection of service, staff member and location — the language option is only a per-event "change the language" setting.
zeeg
The booking page is shareable and embeddable, collects custom intake answers, supports one-on-one, group and webinar formats, and routes by qualification questions; no-show follow-ups carry a reschedule link, and the vendor's own figures show invitees cancelling and rescheduling themselves. We found no public information on seat limits for group bookings, booking pages in several languages, removal of the vendor's logo, or an accessibility statement for the booking flow, which keeps this below the storefront level.
Calendar sync & availability rules
Calendly
Calendars connect for Google, Office 365/Outlook.com and Exchange, busy times are checked to avoid double bookings across up to six calendars per user on paid plans, and availability rules run deep — buffers, minimum scheduling notice, booking date ranges, and meeting limits per day, week or month across event types and hosts. We found no public information on iCloud or CalDAV, holiday and absence schedules, or rooms and equipment that must be free alongside the person, so I stop short of the higher anchor.
zeeg
Sync is documented across Google, Microsoft, Exchange, iCloud and CalDAV, with booked events written to and removed from the calendar, optional cancellation sync back into the product, and the user choosing which calendars are checked for conflicts. Availability rules cover general hours, out-of-office and public holidays, buffers, blocked hours and per-page overrides, plus per-person meeting caps. We found no public information on rooms or equipment that must also be free, minimum notice or booking windows, or documented sync latency.
Team, staff & location scheduling
Calendly
This is where the pages are strongest: round robin with a configurable distribution method, per-host schedules and locations, and distribution statistics exportable as CSV; collective events; routing forms that can route on Salesforce account or lead ownership and block email domains; centrally managed event types and team templates; flexible admin and group-admin roles; and SSO/SAML, SCIM provisioning and audit logs documented. I dock a point only because locations are handled per host rather than as a first-class multi-location object with its own staff.
zeeg
Round-robin comes in a maximum-availability and an equal-distribution mode with high, medium and low member priorities and per-person caps, routing by region, language or form answers; five organisation roles plus team manager and member are documented, with SSO and SCIM provisioning via Microsoft Entra ID, an organisation activity log, and a HubSpot integration that stores routing answers on the contact and updates meeting statuses. We found no public information on collective meetings that need several people at once, several locations with their own staff, organisation-wide templates, or reported distribution fairness, so the top step stays out of reach.
Reminders, payments & no-show protection
Calendly
Email and text reminders before and after events are available on all paid plans, payments run through Stripe and PayPal including an example $150 client deposit, and no-shows at least exist as API events — but the help pages state plainly that the cancellation policy is displayed, not enforced. We found no public information on waiting lists that refill freed slots, no-show or late-cancellation fees, or what the SMS reminders cost; the terms bind you to Twilio's acceptable-use policy rather than pricing the channel.
zeeg
Workflows send email and SMS reminders, follow-ups and surveys to host or invitee around the event, a no-show can trigger a message with a reschedule link, no-shows are markable with rates and attendance trends and segmentation in the built-in CRM, and payment at booking runs through Stripe or PayPal, with SMS credits priced at 10 free per month on paid plans and a 1000-credit bundle for €9.99 a month net. We found no public information on deposits or partial prepayment, a cancellation deadline the system enforces, no-show or late-cancellation fees, or a waiting list that refills freed slots; note also that unused SMS credits expire at the end of each month.
Integrations, API & data export
Calendly
A documented public API with OAuth and personal-access tokens, realtime webhooks with signing keys and per-scope subscriptions, an endpoint that returns invitee names and custom question answers, named CRM integrations (HubSpot, Salesforce, Marketo, Pardot, Dynamics), Zapier, and CSV exports of routing-form responses and round-robin statistics — the data has documented ways out. I stop at the anchor it reaches because we found no public information on published rate limits, an SDK, a self-hosting or migration option, or a single documented full-account export.
zeeg
Automatic video links for Zoom, Google Meet, Teams, Webex and Whereby, Zapier, native HubSpot, Pipedrive and Salesforce, and a developer hub with a Bearer-token API and webhooks whose scopes, test deliveries and error behaviour are spelled out. The part I always look for is absent from the public pages: we found no public information on an export of bookings, customers or form answers, and the terms state the customer is never entitled to a copy of the underlying software.
European sovereignty
Calendly
Calendly, Inc. of Buford, Georgia contracts and processes in the United States, and the subprocessor list shows SMS through Twilio, analytics through Google, Datadog and Cloudflare, AI meeting summaries through OpenAI, and support through Zendesk and Intercom — all but a couple of entries in the USA. The DPA with SCCs, DPF participation, an EEA representative in Berlin and SOC 2/ISO 27001 certifications do real work, but there is no EU hosting option and no EU contracting entity anywhere in the captured pages, so the chain never reaches European ground.
zeeg
Zeeg GmbH of Berlin, registered at Amtsgericht Charlottenburg, hosts on Telekom Deutschland's T Cloud with an included data processing agreement, a data protection officer, and a named subprocessor chain: Brevo in Berlin for email and SMS, Twilio Ireland with ElevenLabs EU data residency for the phone agent, Paddle in the UK as merchant of record, alongside the US corporations Sentry, Webflow, Cloudflare and Intercom, whose data can sit on US servers. The captured pages give different figures for hosting — the terms describe provision exclusively in Germany while the privacy policy names data centres in Germany and the Netherlands. We found no public information on the parent company, security certifications such as ISO 27001 or SOC 2, or a documented data export.
Pricing transparency
Calendly
Standard at "$10 /seat/mo" and Teams at "$16 /seat/mo" billed yearly with monthly and annual billing both shown, a free tier capped at one calendar against six on paid plans, month-to-month or 12-month terms, fees non-refundable and taxes on the customer — the per-seat scaling is honest and legible. But the Enterprise tier is unpriced, round robin sits only in Teams and above, and we found no public information on SMS credit costs or payment processing fees, so a buyer cannot compute the full annual bill from the public pages.
zeeg
Tiers are public at 10 €, 16 € and 30 € per user per month billed annually excluding VAT, the free Starter plan is defined as two booking pages with unlimited events, feature placement is stated — round-robin from Business, SSO and SCIM in Scale, the HubSpot integration in Business or Enterprise — and SMS credits are priced at €9.99 a month net for 1000, with 10 free monthly on paid plans. VAT treatment, the twelve-month annual term with six weeks' notice and monthly no-lock-in billing are all stated. Enterprise is priced only on request, and we found no public information on monthly-billed prices, payment-processing fees for Stripe or PayPal collections, or the per-minute price of the separately sold phone assistant — and unused SMS credits expire at the end of each month.
