ZOREAL Book

Alternatives to Calendly

Calendly is a hosted scheduling service: a person or a team publishes booking links and pages, connects one or more calendars, and an invitee picks a free slot. ZOREAL Book is the scheduling product inside ZOREAL Meet: a client defines the kinds of appointment people can book with them, gets a hosted page and a snippet for their own site, and a guest picks a free slot from a calendar that never overlaps the host’s real one, with a booking that ends in a call ending in a Meet room. This page sets the two side by side: how a booking is made, who the booker is shown to be, which calendars each reads, where the meeting happens, and what each costs.

Information last reviewed 11 September 2026. Compared: Calendly’s scheduling product (event types, availability rules, calendar connections, workflows, payments, embeds and API) with ZOREAL Book. Calendly Notetaker and Callie, the August 2026 AI additions, overlap ZOREAL Meet rather than Book and are out of scope, as are Calendly’s funding and revenue, which are not stated in the public materials we reviewed.

Where ZOREAL Book and Calendly differ

  • Where the booked call happens

    Calendly adds a conferencing link from Zoom, Google Meet or Microsoft Teams to the booking, per its help centre. In ZOREAL Book a confirmed booking with a Meet room location creates a ZOREAL Meet room, joined by link in the browser, where the host can require a presence check at two levels (ZOREAL Presence, ZOREAL Identity), each a full liveness capture and a face match against the document read at enrolment.

  • Who the booker is shown to be

    Calendly shows the host the name and email the invitee typed; verification of the invitee beyond that is not stated in the public materials we reviewed. On an open ZOREAL Book event type the guest confirms their address with a six-digit code before the booking is made, and the guest is not asked for a phone number. Who is in the call is what Meet’s own presence check proves, in the call.

  • Calendar sources

    Calendly connects Google, Outlook/Office 365 and Exchange calendars: one on Free, six on Standard and Teams, unlimited on Enterprise, with one chosen as the main calendar for bookings. ZOREAL Book’s calendars are local or connected Google calendars, read for busy time and written to with the booking; slots are computed live at booking time and a database exclusion constraint refuses a second booking over the same minutes for the same host.

  • What each costs

    Calendly is free with one event type and one calendar connection, then $10 per seat per month for Standard and $16 for Teams on yearly billing, and Enterprise starts at $15,000 per year with a 50-seat minimum (calendly.com, September 2026). ZOREAL Book has no rows of its own on the pricing page. Part of the Meet plans: Free, or Premium for more, with scheduling and calendar invitations on both plans.

Side by side

Comparison of ZOREAL Book and Calendly, based on public materials reviewed on 11 September 2026.

AttributeZOREAL BookCalendly
How a booking is madeSlots are computed live at booking time from the host’s availability schedule, date overrides, public holidays, buffers, minimum notice and booking window, minus busy time from every connected calendar, and a database exclusion constraint refuses a second booking over the same minutes for the same host. A priced event type sends the guest to Stripe Checkout on the host’s own Stripe account, with a ten-minute hold. A confirmed booking with a Meet room location creates a ZOREAL Meet room; the guest gets a manage link and a calendar file, and the host’s connected calendar receives the event.An invitee opens a booking link or page, picks a slot computed from the host’s connected calendars and availability rules (preferred meeting hours, daily meeting limits, buffers, breaks and custom schedules), and types a name, an email address and the event type’s questions. Calendly "checks your calendar for busy times" and adds new meetings to it (help centre article on connecting a calendar, read through a rendering proxy; features page).
Identity of the person bookingOn an open event type the guest confirms their address with a six-digit code before the booking is made; the guest is not asked for a phone number. Who is in a call is what Meet’s own presence check proves, in the call.The name and email the invitee typed. Verification of the invitee beyond that (an email code, an account, a document, a liveness check) is not stated in the public materials we reviewed (pricing, features, security, privacy notice, developer portal and two help centre pages).
Calendar sourcesLocal calendars and connected Google calendars, for busy time and event writing: consent, sync, push, event writing, and blocks written to the account as busy events."Google, Outlook/Office 365, or Exchange": one calendar connection on Free, six on Standard and Teams, unlimited on Enterprise. With more than one connected, one is chosen as the main calendar for bookings (help centre article, read through a rendering proxy; pricing page).
Where the meeting happensA confirmed booking with a Meet room location creates a ZOREAL Meet room, joined by link in the browser; the guest gets a manage link and a calendar file, and the host’s connected calendar receives the event. In the room the host can require a presence check at two levels, ZOREAL Presence (a real, enrolled, live human is present) and ZOREAL Identity (the same plus the verified legal name), each a full liveness capture and a face match against the document read at enrolment. A booking that does not end in a call still lives on the same calendar as the calls."Connect Zoom, Google Meet, or Teams", per the help centre’s summary of its video conferencing article (read through a rendering proxy); the features page lists video conferencing among "100+ integrations" without naming tools.
Reminders and notificationsConfirmation, reschedule and cancel mails with a calendar file; the 24-hour and 1-hour reminders; approval, attendance confirmation, no-show and conflict handling."Automations & Reminders" from the Standard plan; workflows send meeting reminders and follow-ups (pricing and features pages).
PaymentsA priced event type sends the guest to Stripe Checkout on the host’s own Stripe account, with a ten-minute hold; paid is read back from Stripe and refunds are handled. A paid booking asserts that the guest paid before the slot was held for them, referenced to a Stripe payment on the host’s own account."Collect payments at booking via Stripe and PayPal" on Standard and above (pricing page).
PricingBook has no rows of its own on the pricing page; it is part of the Meet plans. Free: unlimited meetings, up to 40 minutes per meeting, "Scheduling and calendar invitations" on both plans.

Enterprise: "Starts at $15k/yr", "Starts at 50 seats", and available in USD and no other currency. USD; geography not stated for the other plans (calendly.com/pricing, September 2026).
IntegrationA hosted page on book.zoreal.com (book.zoreal.com/<handle> lists the active event types and book.zoreal.com/<handle>/<slug> is one of them), a one-tag snippet (embed.js, inline where the tag stands or as a layer on the host’s own button, rendered in an iframe so the host’s page never runs Book’s code and Book never reads the host’s page), and the SDK family the snippet is built from: @zoreal/book-js and @zoreal/book-react on npm, first released 2026-09-10. Calendars are local or connected Google calendars, for busy time and event writing.A REST API to book meetings and read and write scheduling, contacts and Notetaker data; webhooks on scheduling, contacts and Notetaker events; an embed in "inline, popup, or button trigger styles"; "100+ integrations", with HubSpot, Mailchimp and Zapier from Standard, Salesforce and Marketo on Teams and Microsoft Dynamics 365 on Enterprise; mobile apps for iOS and Android; browser extensions for Chrome, Firefox, Edge and Safari and an Outlook add-in.

On an open event type the guest confirms their address with a six-digit code before the booking is made; the guest is not asked for a phone number. Busy time is read from the host’s connected calendars and a booking is written into the host’s connected calendar. A retention period for bookings is not stated on zoreal.com as of September 2026. Organization-level, as zoreal.com lists them for Bynn Intelligence, Inc.: SOC 2 (attestation), PCI DSS (SAQ A), GDPR (data protection), ISO/IEC 27001:2022 (information security certification) and CSA STAR Level One (cloud security self-assessment).

Where ZOREAL Book and Calendly agree

Both are hosted booking pages built on the same idea: the host describes the kinds of appointment on offer and the hours they keep, a connected Google calendar supplies the busy time and receives the booking, and the guest picks from what is left. Calendly "checks your calendar for busy times" and adds new meetings to it. ZOREAL Book reads busy time from the host’s connected calendars, writes the booking into the host’s connected calendar, and writes blocks to the account as busy events. Both send the guest a confirmation carrying the appointment for their own calendar.

Both take money at booking through Stripe. Calendly collects payments at booking via Stripe and PayPal on Standard and above; a priced ZOREAL Book event type sends the guest to Stripe Checkout on the host’s own Stripe account, with a ten-minute hold. Both have a free plan: Calendly’s is "Always free" with one event type and one calendar connection, and ZOREAL Book is included in the Free Meet plan, with scheduling and calendar invitations on both plans and a guest who books and joins without an account.

Neither claims that the person who booked is the person who turns up. Calendly’s public materials make no claim about it. ZOREAL Book says so in writing: a confirmed booking asserts that a guest chose this slot and the slot was free on every calendar the host connected at that moment, and who is in a call is what Meet’s own presence check proves, in the call.

ZOREAL Book may fit you if

  • You want the booked call to take place in a ZOREAL Meet room created on confirmation, where the host can require a presence check at the ZOREAL Presence or ZOREAL Identity level.
  • You want the guest’s email address confirmed with a six-digit code before an open booking is made.
  • You want scheduling with no plan of its own. Included in the Free Meet plan (unlimited meetings up to 40 minutes, scheduling and calendar invitations); a guest books and joins without an account.
  • You take payment at booking on your own Stripe account, with a ten-minute hold and a booking that asserts the guest paid before the slot was held.
  • You want the slot check run live at booking time, with a database exclusion constraint that refuses a second booking over the same minutes for the same host.

Calendly may fit you if

  • You need Outlook/Office 365 or Exchange calendars connected today, up to six per user on Standard and Teams (help centre; pricing page).
  • You distribute bookings across a team by round-robin or route leads by form (pricing and features pages).
  • You want a mobile app for iOS and Android and browser extensions for Chrome, Firefox, Edge, Safari and Outlook (features page).
  • You build on a documented REST API and webhooks, with connectors to HubSpot, Salesforce, Marketo and Microsoft Dynamics 365 by plan (developer portal; pricing page).
  • You want a Zoom, Google Meet or Microsoft Teams link attached to each booking (help centre).
