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 Sales Team Lead
Leads fourteen account executives in three time zones and gets every demo request from the website. Wants inbound demos routed by company size and region, round-robin that is fair and can be checked, two-way sync with Outlook and Google so nobody is double-booked, a video link in every invite, and the booking written into the CRM before the call starts.

Criterion by criterion
Booking page & client experience
Calendly
The booking page covers what my reps' prospects see: one-on-one, multi-host and group event types with their own durations, custom questions including a phone field, cancel and reschedule links in the invitations, automatic host and invitee time-zone detection, a per-event language option, and an embed with custom colours for our own site. Seat limits on group events, white-labelling and an accessibility statement aren't described on the captured pages, so I stop short of the top band.
zeeg
A booking page that embeds on our own website with custom intake forms and pre-questions is documented, and one-on-one, group sessions, webinars and on-site appointments are all covered. The captured pages give me no public information on seat limits for group bookings, pages in several languages, removing their branding, or an accessibility statement, so it sits above a basic page but well short of a storefront.
Calendar sync & availability rules
Calendly
Connected Google, Outlook, Office 365 and Exchange calendars are checked for busy times and new meetings are written back into them — the two-way sync that keeps my team from double-booking — and paid plans connect up to six calendars per user. Buffers, minimum notice, daily, weekly and monthly meeting limits and booking date ranges are all documented; I found no public information on iCloud or CalDAV support or on rooms and equipment scheduling.
zeeg
Sync is documented the way I need it: appointments are created and removed in Google, Outlook, Office 365, Exchange, iCloud and CalDAV calendars, cancellation can sync both ways, several calendars per person can be selected for conflict checks, and availability rules cover buffers, blocked hours, public holidays and out-of-office. I found no public information on rooms or equipment being checked for conflicts, on minimum-notice or booking windows, or on documented sync latency.
Team, staff & location scheduling
Calendly
Everything I run my floor on is evidenced: routing forms that direct a booking by industry, company size and interests; Salesforce lookup routing that assigns by account, contact, lead or opportunity ownership; round-robin that books the next available host with a configurable distribution method and a CSV showing how events were distributed among team members — fairness I can actually check — plus collective events, team templates, centrally managed event types, granular admin roles, SSO with SAML, SCIM provisioning and audit logs.
zeeg
This is the closest to running my fourteen reps: round-robin with an equal-distribution mode so everyone gets the same number of meetings over time, high, medium or low priority per member, caps per person, and routing rules on region and language combined with qualification questions before assignment — my region-and-company-size routing is covered. Five organization roles plus Manager and Member, an activity log, SSO/SCIM with role assignment through Microsoft Entra ID, and routing-form answers landing in HubSpot are all documented; I found no public information on several locations with their own staff.
Reminders, payments & no-show protection
Calendly
Email and text reminders before and after events are built in and customisable from Standard up, payments run through Stripe and PayPal with a deposit option, and no-shows are tracked as events through the API. The captured help page states the cancellation policy is displayed but cancellations are not restricted based on it, and I found no public information on waiting lists or no-show fees.
zeeg
Workflows cover confirmation and reminder emails plus SMS to host and invitee with configurable triggers including before, at start, at end, on cancellation and on no-show, follow-ups and surveys are supported, Stripe or PayPal payment at booking is named, and no-shows can be marked, tracked on contact records and reported as rates. I found no public information on deposits or partial prepayment, cancellation deadlines the system enforces, no-show or late-cancellation fees, or a waiting list that refills freed slots.
Integrations, API & data export
Calendly
A documented API with personal access tokens and OAuth, webhooks with a signing key delivered in real time, and resources covering scheduled events, invitee details including custom question answers, contacts, routing forms and data compliance — enough to write a booking into the CRM before the call starts. HubSpot, Salesforce, Dynamics 365, Marketo, Pardot and Zapier are named, with CSV exports of routing responses and round-robin statistics; I found no published rate limits, SDK or self-hosting path.
zeeg
Video links are created automatically for Zoom, Google Meet, Microsoft Teams and Webex, and the HubSpot integration creates or updates the contact the moment a meeting is scheduled or changed — the booking lands in the CRM before the call starts, exactly what I insist on — alongside Pipedrive, Salesforce, Zapier, a documented versioned API with Bearer authentication, and webhooks including no-show and routing-form events. I found no public information on exporting bookings and customer records out of the product, and rate limits are not stated on the developer pages I read.
European sovereignty
Calendly
The contracting entity is Calendly, LLC in Georgia, USA, the data processing agreement states processing occurs in the United States, and a published subprocessor list names providers — Twilio for SMS, OpenAI for AI features, Google for infrastructure — located almost entirely outside the EU. A data processing agreement, Data Privacy Framework certification, standard contractual clauses and EEA and UK representatives exist, but I found no EU hosting option or EU contracting entity in the captured pages, and the cloud host is unnamed.
zeeg
The imprint names Zeeg GmbH at a Berlin address with a German register number, a data processing agreement is included, and a subprocessor list with locations and Article 28 agreements is published covering Telekom Deutschland hosting, Brevo in Berlin for email and SMS, and Twilio Ireland for calls. The captured pages describe hosting differently — the terms state Germany only while the privacy policy names Telekom data centres in Germany and the Netherlands — and I found no ISO 27001 or SOC 2 certification stated, no documented ownership, and US companies such as ElevenLabs, Sentry and Webflow in the chain under adequacy-decision and standard-contract safeguards.
Pricing transparency
Calendly
The pricing page publishes a free plan plus Standard at $10 /seat/mo and Teams at $16 /seat/mo billed yearly, with monthly or yearly billing, and the terms state month-to-month or twelve-month terms, fees non-refundable, taxes on the customer, and one connected calendar on the free plan versus six on paid. I found no public price for the Enterprise tier, for SMS credits, or for payment processing fees.
zeeg
Every paid tier carries a per-user price quoted as annual-billed excluding VAT (10, 16 and 30 euro per user per month) with feature lists, the Starter plan is permanently free, and SMS credits are priced at 9.99 euro per month net for 1000 with 10 free credits monthly on any paid plan, plus auto-renewal and notice periods in the terms. The Enterprise tier is individually quoted, round-robin and the HubSpot connection sit in Business and above, and I found no monthly price figure shown separately from the annual-billed rates and no payment fees for bookings taken through Stripe or PayPal.
