Build a class booking site for your studio
A booking site for a yoga studio or any class: a public schedule, places that run out, bookings by mail, a blog. Change it by prompt, form or code.
Hosted in the EU, your data in the EU, an EU AI when you choose it. Real code you own.

Built as it is, this description makes the Booking starter at once, with no AI. Change it first and the app follows your words.

What it is
- Class schedule and online booking for a small yoga studio.
- The places left is calculated as the capacity minus the number of its bookings.
- Everyone sees, changes and deletes only their own records.


One change. Three ways.
The app follows.
Say it, fill in a form, or write the line: it is the same change, and the app has it at once.


“Sessions need a room”: the form gains the field, whichever way made it.

How it works
- Describe it, or write the fileYour words become the app's spec: its records, pages and who may do what, in a short file you can read and edit (smithable.yml).
- The app follows the fileChange the description or the file and Smithable rebuilds the app, checks it and keeps its data. Every change can be undone.
- The code is yoursA real TypeScript web app: download it, run it anywhere, or hand it to a client. The engine is open source.
