Free full-stack prompt architect.

Start with the job your app should do. Pick only the capabilities it needs. This free, deterministic architect produces an engineering brief you can copy, review and take into Uvilno.

A brief the builder can act on.

PRODUCT BRIEF
Build this idea faithfully: A client follow-up tracker for an independent design studio
Use audience-appropriate art direction, readable typography, meaningful hierarchy and responsive layouts. Preserve the idea; ask about missing business facts instead of inventing testimonials, customer counts, addresses or claims.

APPLICATION CONTRACT
Before writing modules, establish the supported product scope, primary visitor action, shared design tokens, exact route names, state ownership and component/file boundaries. Deliver focused reusable feature modules. Informational sites need only relevant routes; an interactive app needs Home, Login, Register, Workspace, detail view and Profile. Wire real navigation and URL state.

PERSISTENT DATA
Define data/schema.json with concise domain-specific collection names, typed fields, required values and validated references derived from the idea. State private versus deliberately public records. Use Uvilno.db(collection).list/get/create/update/remove and subscribe for every real record interaction; never substitute disconnected arrays or claim local cache is a server save. Keep real transactional collections empty. If fictional seed records help explain the interface, visibly label them and isolate them from real activity. Shared state must drive lists, filters, counts and charts. Declare bounded transactional automations only where a real product action calls for them.

ACCOUNT BOUNDARY
Use the configured project-isolated Uvilno.auth sign-in flow. Visitor accounts must never replace the creator's Uvilno platform session. Require the actual app identity for private writes; do not infer authority from a role label, query string or localStorage. Handle signed-out, confirmation, loading and failed-sign-in states.

PAYMENTS
Do not introduce checkout, subscriptions or order fulfillment without an explicit supported integration.

AI FEATURES
Do not add an unrelated AI assistant or fake model-generated results.

PERMISSIONS
Keep the permission model as small as the product needs. No client-side control can grant real administration rights.

INTERACTION AND VERIFICATION
Implement the primary flow end to end, including validation, loading, success, empty and retry states. Preserve entered values on failed writes. Verify navigation, keyboard use, 320/390/768/1440px layouts, reduced motion and long content. For persistent data, create/edit a disposable record, reload and verify the saved result. Inspect actual rendered behavior rather than claiming tests passed.

HANDOFF AND REFINEMENTS
List unsupported integrations and hosted dependencies honestly. Source unlock is $4.99 for one project, separate from generation, hosting and services. Exporting source does not migrate identities, private records or credentials. Keep refinements focused using actual file mentions (for example @js/app.js), @db:collection and inspector-selected elements; preserve unrelated routes and behavior.

Name a project, review and edit the brief, then send it explicitly. Planning and building use the normal allowance.

Questions before you choose.

Does this tool spend my studio usage?

No. It assembles a structured brief locally without calling a model. Preparing the brief does not generate a website. Subsequent planning or building inside the workspace uses the normal allowance.

Does selecting Admin create real administrator permissions?

No. The brief distinguishes preview presentation from actual authorization. Real privileged operations need an implemented server-side permission model and must not trust a client-side persona selector.

Will Stripe Checkout accept real payments immediately?

The generated brief asks for the configured Stripe test workflow. Live payments require separate live configuration, provider onboarding and verification; a test receipt is not a sale.

Keep the next step concrete.

Review the SDK and service contract, compare the current plans, or try another engineering tool. Generating an app and operating it are separate decisions.

Check the architecture. Compare the tradeoffs.
