The Cal.com alternative for work that comes back.

What Cal.com Does Well

Cal.com's free plan is unusually generous. Unlimited event types and calendars, mobile and browser apps, over a hundred integrations, two-way Salesforce and HubSpot sync, and Stripe and PayPal payments all sit on the free tier, with no Cal.com fee on Stripe payments (cal.com/pricing and cal.com/blog/freelancers-creators-switching-to-calcom, checked 23 September 2026).

For teams it goes considerably further. Round-robin distribution, routing forms, collective and managed availability, and booking analytics are real capabilities with no Airtym equivalent, and if you are scheduling across several people that decides it.

Two things about Cal.com have changed this year and both are worth stating, because the internet has not caught up with either. Its production code moved closed source in April; the open-source edition is now a separate product called Cal.diy, with the commercial features stripped out (cal.com/blog/cal-diy-open-source-to-closed-source, checked 23 September 2026). And Cal.com Notes, the AI summary feature, is still rolling out behind a waitlist and is reserved for paid plans (cal.com/notes, checked 23 September 2026).

Where the Difference Actually Sits

Cal.com attaches a summary to the booking. Every meeting is its own object and the notes belong to it. That is the right model when meetings are discrete events: an interview, a demo, an inbound sales call, the things Cal.com's customers mostly run.

Airtym attaches it to the person. Every booked call adds to that client's record, so what was agreed in March is in front of you in September without searching a calendar for the booking it belonged to. That is the shape of coaching, consulting, advisory and tutoring work.

The question worth asking is which describes yours. Do you meet a lot of different people once, or do you meet the same people repeatedly? If it is the second, the per-client history is the thing you are buying, and it is on every Airtym plan rather than behind a waitlist.

How Much There Is to Set Up

Cal.com's range is the reason it is powerful. Event types, routing forms, collective versus managed availability: each one is a capability, and an individual user can ignore most of them and still take a booking.

Airtym has fewer decisions in it because it assumes a narrower job. You sell your time, a client books it, pays for it, meets you, and the record writes itself against their name.

What You Need, and What Each One Costs

Cal.com's free plan is the cheaper starting point. What it does not include is the call summary: Notes is waitlisted and, when it arrives, reserved for paid plans.

What the extra spend on Airtym buys is the summary, written from the call and kept on the client's record, so a returning client's earlier sessions are in front of you before the next one.

Airtym's plans differ in call minutes and features, and every plan hosts the call and writes its summary and transcript. Starter is free, with 120 call minutes a month and 10% on paid calls. Lite, at $9.99 a month, raises that to 800 minutes and adds group calls. Pro raises it to 1,800 minutes, adds classrooms and drops the commission. Plus is $39.99 a month and Teams is custom. Paid yearly, Lite, Pro and Plus come with two months free. At about $200 a month in paid calls, Starter's 10% comes to the same as Pro's $19.99 monthly price.
