Calendly compared with Cal.diy, the MIT-licensed community fork of Cal.com: personal booking pages, event types and Google or Microsoft calendar connections, what was removed (teams, routing workflows, SSO) and why its maintainers advise non-production use.
Calendly compared with GPL-licensed Easy!Appointments for customer-facing booking: services and providers, a public booking page and Google Calendar sync on a PHP and MySQL server, against Calendly's routing, integrations and enterprise controls.
Calendly's per-seat Standard and Teams plans and Enterprise minimum compared with self-hosting Cal.diy or Easy!Appointments: no license fees, hosting, calendar API credentials, paid installation services and who maintains it.
What Calendly lets you take out: meeting CSV reports filtered from the Calendar page with invitee, event, UTM and payment fields, no IP address history, and the API v2 and webhooks for scheduling and contact data.
Moving customer-facing booking from Calendly to Easy!Appointments: mapping event types to services and team members to providers, exporting meeting history from Calendly's CSV reports, reconnecting Google Calendar sync, rebuilding reminders and cutting over booking links on the website.
Moving personal booking pages from Calendly to self-hosted Cal.diy: re-creating event types and availability, connecting Google or Microsoft 365 calendars and Zoom, replacing Calendly links, and what to do about team scheduling, routing and SSO that Cal.diy has removed.
For organizations already running Nextcloud: how the Calendar app's appointment slots, with buffers, daily limits, public or secret links and email confirmation, compare with Calendly event types, and where Calendly's routing, payments and integrations have no Nextcloud equivalent.
Calendly Meeting Polls cap a poll at 40 time slots and 40 participants and leave out reminders and rescheduling. This page covers self-hosted Rallly and the Nextcloud Polls app for group date polls, voting without accounts and finalizing the chosen time.
Calendly's customer terms bar protected health information from its service. For clinics and health services: running Easy!Appointments inside your own HIPAA-covered hosting, what booking forms may collect, access controls and logs, and who signs the business associate agreements.
Calendly stores user and invitee data in US data centers and relies on Standard Contractual Clauses for EU transfers. This page covers keeping invitee names, emails and answers in the EU with Easy!Appointments, Cal.diy or Nextcloud appointments in your own datacenter.
