1. Bonsai: free with unlimited students and the most configurable for make-up classes
Bonsai is Spanish software built for yoga, pilates and wellness studios. It's our product, so read this entry with due skepticism and compare it with the others.
Its real difference lies in the business rules you can configure yourself, without relying on support. You can set how many class changes or make-up classes each student can make and decide whether unused sessions from previous months roll over to the next period or expire. Those two rules are exactly the ones most studios with closed groups end up tracking by hand in a spreadsheet.
On the same level is the cancellation policy: you can set a minimum notice period below which students can no longer cancel, so last-minute drop-outs, the ones that leave an empty spot with no time to fill it, are no longer possible. And on the admin side, it includes digital contract signing, so sign-ups and your studio's terms are signed without paper or a separate tool.
The other difference is how the free plan is structured. Bonsai's Seed plan is permanently free and doesn't limit the number of students or staff: it includes up to 100 group bookings a month, waitlist, invoicing, client history and unlimited reminders. On most platforms in this list, unlimited students means upgrading your plan.
It's the same as the Bonup app on the App Store and Google Play: Bonsai is the brand name and Bonup is the name in the stores.
