Grow Roots EngineShip a booking app for your client, without starting from zero.
Grow Roots Engine is a full-stack source-code kit for freelancers and small agencies building booking software. It ships set up for gyms, fitness studios and coaches, and the booking engine is generic, so you can adapt it to other appointment-based businesses. Rebrand it, extend it and deploy it for your client.
One-time payment. One license covers one end product. Instant download.

Who it is not for
Non-developers looking for a no-code product. You need to be able to set up Supabase, Resend and Stripe and to edit code.

FAQ
Is it only for gyms?
No. The default text and business types are for gyms, studios and coaches. The booking engine itself (services, staff, availability, capacity, clients) is generic. You can adapt it to other appointment-based businesses by editing the copy and business types. It has not been tested for other industries out of the box.
Can I use it for client projects?
Yes. One license covers one end product, which can be your own product or a single client's. For more projects, get in touch for a multi-project license.
Can I resell or publish the code?
No. You may not resell, redistribute or publish the source code, original or modified, as a template, starter kit or in a public repository.
Does it process real payments?
Stripe is wired in test mode and you add your own keys. The CMI (Morocco) integration is a mock only. Review and complete the payment flow before going live.
What do I need to run it?
Node.js 20+, a Supabase project, a Resend account with a verified domain, and optionally a Stripe account. The README walks you through setup.
What is your refund policy?
Because this is a digital download of source code, sales are final. If setup fails, contact me within 7 days and I will help you fix it. See the refund policy.
