Someone sends you a booking link, you like how it works, and you go looking for the catch. Is Cal.com free? Yes, for one person, and more generously than most scheduling tools. Cal.com's own pricing page offers scheduling for free with no usage limits, then points you at a premium plan the moment you need anything collaborative. That is the answer in miniature. The rest of this post is the shape of the limits, in words rather than numbers, plus the part most posts on this question skip: since April 2026 the open source version of Cal.com is a separate product with a different name, and running it yourself is a real cost even when the license is not.
No prices appear below, including ours. Plans change. The shape of a plan changes more slowly, and the shape is what you actually need to know.
The short answer: free for one person
The free plan is built around a single user. Cal.com describes it as everything you could need for scheduling as an individual, and that is a fair description rather than marketing. Collaborative features are what the premium plans are for.
So if you are a freelancer, a tutor, a coach, a recruiter working alone, or one salesperson with a link in your email signature, the free plan is a complete product and you can stop reading at the next section. If you are two people who need to share availability, free is where the trial begins.
What the free Cal.com plan includes
More than people expect:
- Unlimited event types. Create as many booking templates as you need for different meeting types.
- Unlimited calendar connections. Connect multiple calendars to sync availability and prevent double bookings.
- Unlimited bookings. No cap on the number of meetings you accept.
- Buffers and minimum notice. Add time before or after meetings, and require bookings to be made a set amount of time in advance.
- Payments. Request payment upfront through Stripe or PayPal before someone completes a booking.
- Integrations. An app store with a growing library of integrations, plus a mobile app and a browser extension.
- Reschedule and cancel. Organizer and attendees can move or cancel a meeting from a link instead of writing emails.
That list is why "is Cal.com free" is a harder question than "is tool X free". Plenty of free plans cap you at one event type or one connected calendar. This one does not. If you want the contrast, our write-up of the Calendly free plan limits covers a free plan built on a very different idea of generous.
Where the free plan stops
A few walls, in the order most people hit them.
One user. The free plan is scoped to an individual. Nothing about it bends to a second person.
Team scheduling. Round-robin, which distributes bookings across a team automatically based on availability, weights or priority rules, is a team-plan feature. So are collective events, which schedule meetings where multiple team members attend together. If the concept itself is new to you, we explain what round-robin scheduling is and who actually needs it.
Your branding. Removing Cal.com logos and references from your booking pages is a paid feature. On free, removing it is not one of your options.
Routing and automation. Routing forms, which route bookings to the right person or team using rules, and workflows, which automate reminders and follow-ups around bookings, both sit above the free plan.
Company controls. SAML SSO, SCIM provisioning, sub-teams and a company subdomain at yourcompany.cal.com belong to the organization plan.
None of that is a trap. It is a normal open-core split, clearly labeled. It just means the honest answer is "free until a second person is involved".
"Free and open source" changed meaning in April 2026
This is the part that makes old answers to this question wrong.
In April 2026 Cal.com moved its production codebase from a public repository to a private one. The public repository is now calcom/cal.diy, the open-source, self-hostable, community-driven version of Cal.com. Cal.diy is described as the open source community edition spun out of Cal.com. Commercial and enterprise features that only apply to Cal.com as a managed service were removed, while all free features remain.
In practice: Teams, Organizations, Insights, Workflows and SSO/SAML are gone from the open source edition. The self-hosting docs repeat the same split feature by feature, with teams, team event types, managed events, instant meetings, routing forms, workflows, insights and SAML SSO marked as absent on the Cal.diy side.
So the reasoning "it is open source, so I can self-host and get the paid features for nothing" does not work. The paid features are precisely the ones that were taken out.
Self-hosting is free the way a puppy is free
The code is yours to run. The running of it is a job.
There is no hosted Cal.diy. The README says it plainly: you run it on your own infrastructure. To run it you install Node.js, yarn, Git and PostgreSQL, with Prisma handling database maintenance. You generate your own secrets for cookie and credential encryption before you go anywhere near production. Several features need cron jobs, which you set up yourself according to whichever platform you host on. And the free-license software can still land you on a paid host: deploying to Vercel currently requires their Pro plan, because of the serverless function limits on the free one.
Then there is the warning the project puts above everything else. Self-hosting requires advanced knowledge of server administration, database management and securing sensitive data, and you should proceed only if you are comfortable with those responsibilities. Cal.com, Inc. does not guarantee the security and safety of the open source project, which is community maintained and recommended for personal, non-production use.
Read that as a cost line, because it is one. Zero license fee, plus a database you administer, a server you patch, upgrades you apply, and the security of your clients' meeting data sitting on your side of the fence. For a hobbyist that is a fun weekend. For a one-person consultancy it is a second unpaid job.
When Cal.com is the better pick
We are not neutral, so here is the honest list.
- You want the code. Cal.diy is the self-hostable open source edition, and nothing we make is.
- You need payments on bookings. Cal.com's free plan takes payment upfront through Stripe or PayPal. A WhenNOT booking page has no payment step at all. If money changes hands at booking time, this is not a close call.
- Your bookings have to reach other systems. CRM sync, routing by account ownership, automation across a long list of apps: Cal.com's free plan already lists two-way Salesforce and HubSpot sync and 100+ apps in its App Store, and routing forms sit on the paid Teams plan.
- You run a sales or support team on rotation. Round-robin distribution across a team is a real feature there and it is not one of ours.
What free means on our side
WhenNOT runs booking pages and group polls in the same account, and there is no paid plan to graduate to. Group polls, booking pages, calendar connections, the Slack app and the ChatGPT and Claude connectors are all free, with no plans, no paywall and no ads.
The booking page half works like this. You connect as many Google and Microsoft accounts as you have, and every one of them is checked before a time is offered, which is the fix for the oldest problem in self-serve scheduling: a personal appointment that your work booking link cannot see. We wrote that one up separately in how to stop double booking a work and personal calendar. You set opening hours per weekday, with as many windows a day as you like. Guests book without an account and move or cancel their own booking from the confirmation.
One honest caveat, because it is the kind of thing vendors bury: Meet links need a Google Workspace calendar and Teams links need a Microsoft 365 work or school calendar. On a personal Gmail or Outlook.com calendar the invite goes out without a video link.
The other difference is a whole feature the question never covers. Cal.com is built for booking, and its plans list no group poll. If what you actually need is a date a group of people can make, a booking link is the wrong tool and both products' free plans are beside the point.

FAQ
Is the free Cal.com plan limited in how many meetings I can take?
No. The free plan accepts unlimited bookings, with no restriction on the number of meetings, and no limit on event types or connected calendars.
Is Cal.diy the same thing as Cal.com?
No. Cal.diy is the open source community edition that was spun out of Cal.com. The commercial and enterprise features were removed from it, and only the free features remain.
Can I self-host and avoid paying for the team features?
No. Teams, Organizations, Insights, Workflows and SSO/SAML were removed from the open source edition. Self-hosting gets you the individual product, on hardware and a database you maintain yourself.
Does Cal.com do group availability polls?
Its plans list no group poll. Picking a date with a group is a different job from letting one person book you.
Different situation?
If the problem is seven people and one weekend rather than one client and one hour, start a free group poll instead: people cross out the days they cannot make, and the dates with the fewest conflicts rank first. Nobody needs an account to answer.
Otherwise, the question behind "is Cal.com free" is usually "what will this cost me once it works". Here is our answer to that: get a free booking page that checks every calendar you connect before it offers a time.
