A business breaks on the edge cases.
Double bookings, partial refunds, duplicate webhooks, commission on a cancelled sale. Each one takes a week to find in production.

Start from tested Modules
Each Module ships with its schema, screens, routes and workflow tests. Your agent switches on what the business needs and writes only what's specific to it.
Booking
Overlapping slots, walk-ins, no-shows, therapist swaps, deposits.
Payments
Card and QR checkout, partial refunds, duplicate webhooks, terminals at the counter.
Staff pay & commissions
Commission rules per service, reversals on refunds, time clock, payout runs.
Point of sale
Split bills, discounts, receipt and kitchen printers, end-of-day close.
Online ordering
Stock running out mid-checkout, pickup times, order status messages.
Customer accounts
Sign-in, booking history, saved cards, LINE and email notifications.
Test it like production.
If it passes, it works in prod.
Every app gets its own database branch and a test harness that runs your real routes against it. No mocks, so a green run means the release works.

Same stack as prod
Postgres, auth, payments and email behave the same in tests and previews as in production.
Workflow tests
Agents test whole flows, from booking to checkout to payout, not functions in isolation.
Checked schema changes
Migrations are checked before they reach production. Nothing gets dropped by accident.
A preview per branch
Click through a change on its own copy of the data before it ships.
For agencies and freelancers
Ship it like you vibecoded it.
Get an app that’s actually production-ready.
Features are Modules, not code woven through the app. When a client adds online ordering or drops memberships in week six, your agent switches a Module instead of rewriting the system.
Days, not months
Start from your own Blueprint and tested Modules. Your agent writes only what's specific to this client.
Scope changes are cheap
Add point of sale or drop memberships mid-project. Modules switch on and off without touching the rest.
Customize without forking
Restyle or extend a Module's screens. Platform fixes still reach your client's app.
We run it after handover
Hosting, monitoring and updates stay with us, not on your retainer.
Build with your agent.
Run on Stardeck.
One command creates the app, connects the Stardeck MCP server to your agent and pulls your environment.
