Where they differ
Cal.com 3 · Calendly 2 · open 0- 01
Control over hosting and data
Cal.com publishes an MIT-licensed community edition, Cal.diy, that anyone can run on their own server, and offers on-premise access to enterprise customers by invitation, alongside configurable data residency. The community edition leaves out teams, organisations, workflows and single sign-on. Calendly's pricing page describes hosted plans only. For buyers who need a self-hosted route, Cal.com is the one that documents it.

Upkeep and stability
Self-hosting is a maintained service, not a download: the Cal.diy guide asks for Node.js, PostgreSQL and someone who understands server and database administration, and recommends it for personal, non-production use. Cal.com's cloud removes that work. Calendly's draw is that it simply works for the recipient and the sender. For a small office with nobody technical, Calendly is safer.

Building scheduling into your own product
Cal.com's API is designed for embedding, and its site lists an enterprise API, embeds and Cal.com Atoms as separate solutions, alongside routing forms and round-robin teams on the Teams plan. Calendly's pricing page concentrates on integrations such as Salesforce, HubSpot, Marketo and Pardot. For a team that writes code against its scheduling, Cal.com offers more to work with.

What the free plan covers
Cal.com's free plan is for one user and lists unlimited event types and calendars, Stripe and PayPal payments and Salesforce and HubSpot sync. Calendly's free plan is limited to one event type and one calendar connection, with payments and HubSpot starting on Standard at 10 dollars a seat. For an individual who wants to pay nothing, Cal.com gives noticeably more.

What the invitee experiences
Calendly's advantage is recognition: recipients know the link, know it works and book without a covering explanation. That removes friction no feature list captures. Cal.com matches it on routing forms and round robin, and its Teams plan removes Cal.com branding, but the name is less familiar to a prospect. When the person booking is a prospect, Calendly is the smoother experience.

When neither fits
If your organisation already pays for Microsoft 365 and wants no new vendor at all, Microsoft Bookings runs inside the existing tenant. If appointments consume rooms and equipment as well as people, TIMIFY is built for that and both of these are not.
Cal.com or Calendly: questions
4 answersIs Cal.com free compared with Calendly?
Both have a free plan for one person. Cal.com's includes unlimited event types; Calendly's allows one. Paid team plans are listed at 12 dollars per user a month on yearly billing for Cal.com Teams and 16 dollars per seat a month for Calendly Teams.
Can I self-host Cal.com for a whole team?
Not with the free community edition as published. Cal.diy is MIT-licensed and self-hostable, but teams, organisations, workflows, insights and single sign-on have been removed from it. Cal.com points commercial users to its hosted service or to on-premise enterprise access by invitation.
Is Cal.com a real alternative to Calendly for teams?
Yes, for engineering-minded buyers. Cal.com Teams has routing forms, round robin and booking analytics, and Organizations adds SAML single sign-on and SCIM at 28 dollars per user a month on yearly billing. Calendly offers mature routing, Salesforce updates and a link recipients recognise.
Which has the stronger compliance options?
Cal.com lists SOC 2, HIPAA and ISO 27001 compliance with its Organizations plan, plus SAML single sign-on. Calendly offers single sign-on as an optional add-on on Teams and includes it, with audit logging and domain control, on Enterprise, which starts at 15,000 dollars a year.
