Calendly vs Sesami

The quickest way to tell these apart: Calendly is built around a person’s availability, and Sesami is built around a service you sell.

That is why Calendly asks you to define a thirty-minute meeting and Sesami asks you to define a ninety-minute treatment that needs a specific therapist, a room and a price. Both then show a calendar. What sits behind the calendar is completely different.

Side by side

	Sesami	Calendly
The unit being booked	A service, with a price, a duration and the resources it needs	A meeting slot on someone’s calendar
Where it happens	Your storefront, on your domain	A Calendly scheduling page
Payment	Your own checkout, or settled later at the counter	Collected through Calendly’s payment integrations
Sold with other things	A booking sits in the same basket as products	Scheduling only
Resources	Staff, rooms and equipment, several per service	The host of the meeting
Locations	Separate calendars, staff and hours per branch	Set per event type
In person	Rung up through Shopify POS	Not a point-of-sale tool
Group sessions	Classes and workshops with capacity per slot	Group events with a cap
Build on it	Public API, SDK, an app platform, and agent access	An API and a large integration directory

Where Calendly is the better answer

Calendly is very good at the thing it is for, and it would be silly to pretend otherwise. If the job is getting a meeting into two busy people’s calendars with the least possible friction, Calendly does that more simply than any commerce platform will, and its integration directory is far larger.

Sales calls, demos, interviews, consultations, office hours, anything internal: that is Calendly’s territory. If your meetings are free and the only thing that matters is finding a mutually free half hour, adding a commerce platform underneath is weight you do not need.

Where Sesami is the better answer

A service needs more than a free half hour. A treatment might require a specific therapist and a specific room, and can only be offered when both are free. A test drive needs a car and someone to take it out. A class has a capacity. A branch has its own hours and its own staff.

That is the work Sesami does, and none of it depends on money changing hands. Test drives, viewings, clinics and consultations are all free bookings that still need a resource, a location and a real calendar behind them.

When there is a price, the commerce questions arrive too. How is it taxed? Does a discount code apply? Can they buy something at the same time? What happens if they pay at the counter instead? Sesami answers those by putting the booking through the checkout you already run, with your payment methods, taxes and gift cards, and reporting it next to the rest of your revenue. Sesami is built around those constraints because that is what selling services looks like.

There is also a difference in kind, not just in scope. The others are software you run your business on, and their APIs exist so other systems can talk to them. Sesami is a platform you build on: the same booking engine the app runs on is public, with an SDK, an app platform, and access for AI agents that can book, reschedule and answer on a customer’s behalf. If you want a booking experience nobody else has, or you expect agents to be doing the booking before long, that is the difference that matters most.

A fair summary

Use Calendly if you are scheduling meetings.

Use Sesami if you are booking a service rather than a meeting: something that needs a room, a car, a chair or a class, at one of your locations, with an API and SDK underneath when you want to build your own. Whether money changes hands is a separate question — a lot of what Sesami books is free.

Sesami runs deepest on Shopify, where a booking becomes a product in your catalog. It is not limited to it: the Sesami Booking Button embeds in WordPress, Squarespace, Webflow, Framer or plain HTML, and a hosted Sesami page takes bookings and payments on its own. Those are rolling out through early access now.
