The builder generating a live, working preview — not a mockup.

Built for how you actually work

Real example: ModernClinic
A booking-driven clinic app built on GYSM is already live — the same builder generates the calendar, availability, and intake flow your service needs.
Deposits & payments at checkout
Take deposits or full payment at time of booking with Stripe checkout wired in automatically — no separate payments integration.
Client accounts, done for you
Sign-up, login, and booking history are wired in from the first prompt, so clients can manage their own appointments.
