A custom storefront
Sesami Small at $19/month lists API/SDK access. Cowlendar’s public API is beta and has a defined endpoint set; compare the actual technical requirement.
Sesami alternatives.
Compare the implementation, too.
Sesami is worth evaluating as a retail booking platform with an API, SDK and resource model. Small includes five resources; Pro adds groups and Klaviyo with twenty resources; Premium lists forty resources and multi-location. A lower app subscription does not automatically replace a custom implementation.
What would make switching worthwhile?
Sesami may be the right choice when your agency needs its SDK or your retail operation values its resource model. A lower subscription does not automatically replace a custom implementation.
YOUR DECISION STARTS HERE
The differences that matter for Sesami users.
Groups and lifecycle marketing
Sesami Pro is $129/month and lists group appointments, Klaviyo and reports. These are different requirements from basic appointment booking.
Multiple retail locations
Premium is $299/month and lists multi-location with forty resources. Include implementation, resource mapping and staff operations in the decision.

COMPARE THE MONTH YOU ACTUALLY RUN
Starting prices only tell half the story.
Two concrete examples for merchants considering a move from Sesami.
Basic calendar-connected appointments
20 bookings × $40.00$800.00 booking revenue · Google Calendar
| App | Qualifying plan | Monthly USD estimate |
|---|---|---|
| Sesami | Small$19.00 plan | $19.00 |
| Cowlendar | Starter$13.99 plan | $13.99 |
| Apntly | Pro$9.00 plan | $9.00 |
This compares one operator and Google Calendar, without custom SDK development or a multi-location implementation.
Booking events for Klaviyo
40 bookings × $50.00$2000.00 booking revenue · Klaviyo
| App | Qualifying plan | Monthly USD estimate |
|---|---|---|
| Sesami | Pro$129.00 plan | $129.00 |
| Cowlendar | Basic$29.99 plan | $29.99 |
| BookX | Business$39.99 plan | $39.99 |
Klaviyo moves Sesami to Pro. The example excludes development work and compares the documented integration tiers; Cowlendar’s integration is beta.
Estimates use the lowest documented plan covering the stated features and volume, for one service, one location and one operator. Excludes taxes, Shopify and payment fees, SMS, extra staff logins and optional add-ons. “Not established” means the checked sources do not confirm this exact combination or quota; it does not mean the app cannot do it.

01 · A CONFIGURABLE BOOKING APP
Cowlendar
Evaluate the standard booking flow and varied service types before commissioning a custom experience.
Who should consider it
Appointments, classes, bundles and rentals in one app, with all features available from the free plan.
The tradeoff to check
All features are available from the free plan. Paid pricing follows booking revenue; usage allowances and optional messaging charges still apply. See the pricing page for full details.
Current plans & concrete limits
- Free $0
- All features included · see free-plan allowance
- Starter $13.99/month
- Up to $1,000 booking revenue
- Basic $29.99/month
- Up to $3,000 booking revenue
- Growth $59.99/month
- Up to $10,000 booking revenue
02 · LOCATION-BASED OPERATIONS
BookX
Compare staff/location tiers and required integrations for a growing service business.
Who should consider it
Businesses comparing location counts, team capacity and seasonal pricing.
The tradeoff to check
The listing separates basic Google Calendar integration from two-way sync on Business. Do not assume the cheaper plan includes the same synchronization behavior.
Current plans & concrete limits
- Free $0
- One service and one team member
- Starter $9.99/month
- Up to 5 locations/team members
- Growth $19.99/month
- Up to 10; deposits and seasonal pricing
- Business $39.99/month
- Up to 20; two-way sync and Klaviyo
03 · A SMALLER APPOINTMENT BUDGET
Apntly
A useful shortlist when simple service scheduling matters more than custom development tooling.
Who should consider it
A solo service or a team prioritizing a low fixed subscription cost.
The tradeoff to check
Group appointments, custom questions, calendar integrations and deposits are listed on Pro. Check the exact workflow before choosing Starter.
Current plans & concrete limits
- Free $0
- One service and one team member
- Starter $5/month
- Unlimited services and team members
- Pro $9/month
- Groups, calendar integrations and deposits
04 · CLASSES AND EVENTS
Easy Appointment Booking
Test event packs, waitlists and operational staff access on the plan that includes them.
Who should consider it
Workshops, tastings and teams prioritizing event operations and packages.
The tradeoff to check
The listing mentions team logins at $8 per staff member and Klaviyo/Flow on an Ultimate $99 plan. The headline $39 tier is not the full cost of every advertised capability.
Current plans & concrete limits
- Free $0
- One event or service
- Standard $15/month
- Reminders and intake questions
- Pro $29/month
- Google Calendar/Zoom; product upsells
- Pro Plus $39/month
- Waitlists, packs and deposits
- Ultimate $99/month
- Klaviyo and Shopify Flow (listed upgrade)

YOUR MIGRATION CHECKLIST
Test the reason you are switching.
- Inventory the custom work List the theme changes, SDK usage, endpoints and automation events the existing installation depends on.
- Map resources to the new setup Confirm how people, rooms or counters translate into the alternative app. Do not compare unrelated resource counts as if they were identical.
- Budget the transition Allow for implementation and acceptance testing as well as the monthly subscription. Reconcile future bookings before switching the storefront.
Sesami alternatives: common questions.
Does Sesami offer a free plan for a live store?
The free tier in the checked listing is for development stores. Small starts at $19/month for a live-store feature set.
Can Cowlendar replace a Sesami SDK implementation?
Not automatically. Compare the required custom interface and API endpoints. Cowlendar’s beta public API supports defined booking operations, which may not match a storefront built around another vendor’s SDK.
