Cowlendar vs Sesami.
Powerful booking, without a big retail budget.
Cowlendar puts groups, bundles, deposits and subscriptions in one feature set. Sesami is attractive for agency-led retail projects, but groups and Klaviyo require its $129 Pro plan.

MAKE THE SWITCH WITH CONFIDENCE
Bring your hardest booking to the trial.
Sesami is a strong candidate when your agency wants an SDK and control over the booking experience. Set aside time to assess the implementation and maintenance work alongside the monthly subscription.
For a live store, compare the required Sesami tier with Cowlendar’s free plan and revenue-based paid plans. Sesami’s free development offer is for building and testing.
For group services or multiple locations, price Sesami at the tier that includes those needs. A larger retail operation may value its resource model and architecture support; a simpler merchant may prefer Cowlendar's common feature set.
Your questions, answered.
Does Cowlendar have a free plan?
Yes. Cowlendar has a free plan with all features. Usage allowances apply; the pricing page shows the limits and revenue-based paid tiers.
Is Cowlendar cheaper than Sesami?
It depends on the features and booking revenue. Use the calculator above: it compares the lowest documented plan for your selected features and shows the assumptions, rather than comparing unrelated starting prices.
Does Cowlendar support subscriptions, an API and webhooks?
Yes. Recurring service subscriptions and bundles are supported. The public API and webhooks are documented as beta, including subscription-credit bookings and eight webhook events. Review the linked API limitations before planning an integration.
When should I choose Sesami instead?
Retail teams or agencies building a customized booking experience. The free tier is for development stores. Group appointments and customer rescheduling are listed on Pro; multi-location is listed on Premium. Compare the required tier, not Small alone.
