Cal.com vs Calendly Comparison 2026
Cal.com is open-source scheduling that can run on your own domain and database, with a free plan that never caps meetings for one person. Calendly reads the calendars you connect and offers only the slots none of them have taken, with buffers and daily caps enforced automatically, but its free plan allows only one event type. Cal.com's free plan also takes payment through Stripe or PayPal; on Calendly that needs the paid Standard plan at $10 a seat a month. Self-hosting aside, the free tier is where these two pull furthest apart.

Cal.com
Open-source scheduling you can host yourself
Cal.com does what Calendly does and publishes its source, which matters to anybody who wants booking on their own domain and their own database. The individual plan is free with no meeting cap. Self-hosting is real rather than theatre, though it is a weekend rather than an afternoon.
Our note
Taking payment for calls is free here and is a paid feature almost everywhere else. That single difference is the reason most people switch.

Calendly
A booking page that reads your own calendar
Calendly publishes the times you are genuinely free and lets somebody claim one, which settles in a click what usually takes three emails. Buffers, round robin and paid bookings are there when the calls start earning. The free plan allows one event type, so anybody running a coaching call and a sponsor call from the same calendar pays.
Why people weigh these two
- Calendly instead of Cal.com
- Calendly does the same booking-page job with the most polish and no setup, free tier included and paid from $10, if self-hosting and open source are not the point for you.
- Cal.com instead of Calendly
- Cal.com is the open source version of the same booking job, hostable on your own domain, with a free plan and paid from $12.
Which one should you pick
Take Cal.com if you want booking on your own domain, or if you take payment for calls and would rather not pay extra for the privilege. The individual plan is free forever with no cap on event types, calendars or meetings, and Stripe and PayPal are already switched on. Self-hosting is genuinely available too, though budget a weekend for it rather than an afternoon.
Take Calendly if a team wants the most polished experience with nothing to set up, and self-hosting is not a consideration. The free plan connects one calendar and publishes one event type only, so anybody running two kinds of call, a coaching session and a sponsor chat, will pay for Standard at $10 a seat a month billed yearly. That single event type limit is what pushes most solo users onto a paid plan faster than on Cal.com.
Common questions
- Which one has the more generous free plan?
- Cal.com. Its free plan covers one user with no cap on event types, calendars or meetings, and Stripe and PayPal payments are already included. Calendly's free plan allows only one event type and one connected calendar, and payments need the paid Standard tier at $10 a seat a month.
- Can I take payment for a call on the free plan?
- On Cal.com, yes: Stripe and PayPal are built into the free plan. On Calendly, no. Paid bookings need at least the Standard plan, which starts at $10 a seat a month billed yearly.
- Can I run Cal.com on my own server?
- Yes. Cal.com is open source and genuinely self-hostable, on your own domain and database, though it is realistically a weekend project rather than an afternoon one. Calendly has no self-hosted option; it is a hosted service only.
- Can I move my Calendly links to Cal.com?
- Yes, Cal.com has a one-click Calendly import, so existing event types come across instead of being rebuilt from nothing.
