Cal.com's free plan has webhooks, workflows and unlimited event types; Calendly's has one event type and no webhooks. Which to pick for a reminder chain.

A booking tool has one job in an automation: tell the next system that a meeting was booked, moved or cancelled, the moment it happens. Everything else, from the branding on the booking page to the number of calendars it checks, is secondary. This page compares Cal.com and Calendly on exactly that job, on their free plans, with every claim read off the vendors' own pages on 29 September 2026.

We are a Cal.com affiliate. Calendly has no affiliate programme, so there is no link to it here, and nothing on this page depends on which one you choose. Where Calendly is the better pick, the page says so.

The comparison

The pattern is simple. Calendly's free plan is a booking page. Cal.com's free plan is a booking page plus the plumbing. For a business that only needs a link to send people, both work. For a business that wants the booking to start anything, from a row in a sheet to a reminder to a Telegram alert, only one of them does it without a card.

Webhooks: the line that decides it

A webhook is the booking tool calling a URL you give it, with the booking's details, the second something happens. Make listens at that URL and runs the scenario. No polling, no delay, no credits spent while nothing is booked. If you are new to those terms, the credits page explains them once.

Cal.com lists webhooks among the features free users get, in its FAQ (checked 2026-09-29), and its help centre lists twenty trigger events: Booking Created, Cancelled, Rescheduled, Requested, Paid, No-Show Updated, Meeting Started and Ended, Form Submitted, and more. The one that matters for reminders is Booking Created; the one that matters for measuring the problem is Booking No-Show Updated, which fires when a host marks an attendee as absent.

Calendly's help centre says webhooks are available on Professional, Standard, Standard Plus, Teams, Teams Plus and Enterprise (checked 2026-09-29), and lists three events: invitee created, invitee cancelled and routing form submissions. Make's own documentation for its Calendly app is blunter: the Watch Events module requires a paid Calendly subscription, and the webhook feature is not included in free Calendly plans (checked 2026-09-29).

Reminders: built in, or built by you

Both tools can send reminders to the person who booked. On Cal.com, workflows are on the free plan, and the FAQ says there is no limit on the number of workflows or on the events they connect to (checked 2026-09-29). A workflow has a trigger (booking created, a set time before or after the meeting, cancelled, rescheduled) and an action: an email, an SMS, a WhatsApp message or a webhook.

On Calendly, the equivalent feature, called Automations, is on Standard and above, with up to 50 per user or team (checked 2026-09-29). The triggers are similar: new booking, before the event starts, event starts, rescheduled, ends, cancelled, and no-show marked.

So the honest position is this. If your reminders are the standard kind, one or two emails before the meeting, Cal.com does them free and Calendly does them for $10 a seat a month billed yearly (checked 2026-09-29). Neither needs Make for that. Make earns its place when the reminder must also update your sheet, alert your phone, or send from your own Gmail, and when the same booking should trigger other things: a confirmation to the team, a row in the meetings log, a follow-up after the meeting.

Which to pick for the no-show reminder chain

The chain on this site has two parts. The first writes every booking into a meetings sheet with status "booked". The second runs every morning, finds tomorrow's meetings, sends each client a reminder with a "can't make it" link, and marks the row. The sheet is the record; the reminder is one scenario; the booking tool is only the trigger.

For that trigger, use Cal.com. Its Booking Created webhook, or the Watch Booking Created module in Make, writes the row the moment a client books. On the free plan. If the client has no booking tool at all, or does not want one, a free Tally booking form does the same job without checking availability; that blueprint is below too.

The scheduling tool we use as the trigger: real availability, a webhook on every booking, and a Make module, all on the free plan: Set up free scheduling → paid link · we earn a commissionPaid link. If you upgrade to a paid plan through it we earn 20% from Cal.com for a year, and you get 20% off for 12 months. The free plan covers one calendar.

For the evidence behind the reminder and the full three-message chain, with templates, see the no-show pillar page: the studies, what they measured, and the 48-hour, 24-hour and 2-hour messages.

When Calendly is the better pick

• The client already pays for Calendly Standard or Teams. Webhooks and Automations are there; moving to save $10 a month (checked 2026-09-29) is not worth the migration of every link they have ever shared.
• The client's CRM or sales tooling has a first-class Calendly integration and no Cal.com one. Check before choosing; the CRM usually decides.
• The team books as a group and wants collective and round-robin events with a familiar interface, and the budget already includes a paid plan. Both tools do this on paid tiers; pick the one the team will actually use.
• You need nothing but a link. On a booking page alone, the two free plans are close, and Calendly's is the one more clients already know.

Setting up the Cal.com trigger in Make

1. In Cal.com, create the event type (for example "Consultation, 30 min") and connect your calendar. Both are on the free plan (checked 2026-09-29).
2. Install the Make app from Cal.com's app store and generate an API key in your account settings; Make's Cal.com app asks for that key.
3. In Make, add "Cal.com — Watch Booking Created" as the first module. It is an instant trigger: Make creates the webhook for you.
4. Map the booking's name, email, date and time into a Google Sheets "Add a Row" module with status "booked" and the date as YYYY-MM-DD, which is what the reminder scenario searches for.
5. Import the no-show reminder blueprint as a second scenario, point it at the same sheet, and set it to run every morning.
6. Book a test meeting from another email address. Check the row, wait for the morning run (or run once), and read the reminder you receive.

What does not work

• Calendly's free plan cannot trigger anything server-side. There is no webhook, and Make's Calendly module will not connect to it. An embed on your own site can detect a booking in the visitor's browser, but that is code on the page, not a reliable trigger.
• A Cal.com workflow reminder and a Make reminder are two reminders. Choose one path per message, or the client gets both.
• Cal.com's pricing page lists email and SMS notifications on the free plan (checked 2026-09-29), but SMS delivery to attendees has had plan and region conditions over time. Test one booking end to end before promising a client an SMS.
• Both tools' free plans are for one user. The moment two people need their own availability under one brand, both require a paid team plan: Cal.com Teams from $12 per user/month billed yearly, Calendly Standard from $10 per seat/month billed yearly (checked 2026-09-29).
• Cal.com's free plan shows Cal.com branding on the booking page. Removing it needs a team plan (checked 2026-09-29). Calendly removes branding on Standard.
