# Which AI app builder fits a database and authentication project?

The choice depends on the data model, authorization and deployment requirements. Uvilno provides typed managed collections and project-isolated visitor identities, with configured OAuth providers and email accounts. Validate persistence, ownership and unsupported integrations in a working slice before choosing any platform for a production application.

Start with a visitor and a record: who creates it, who reads it and which changes are permitted? An attractive login screen or a visible admin label does not prove that those boundaries are enforced. Specify the permissions and test them using separate disposable identities.

Uvilno can support the declared collection and identity workflow, while broader organizational sharing or specialist compliance requirements need explicit review. Compare those requirements against other builders' documented capabilities; no single product is established as universally best by this page.

## What to verify

| Check | Published behavior | Verification |
| --- | --- | --- |
| Persistence | Supported CRUD uses the hosted entity service. | Create, edit, reload and retrieve a test record. |
| Identity | App visitors use identities separate from creator sessions. | Check creator identity before and after app sign-in. |
| Permissions | Presentation personas do not grant server access. | Test actual unauthorized requests with another visitor. |

## Steps

1. Write the collection and owner rules.
2. Choose one account-to-record journey.
3. Test it before expanding the route list.

## Editable starting brief

Plan a customer follow-up tool with app sign-in, private customers and private follow-ups linked by valid references. Include list, detail, create, edit, deletion confirmation and Profile routes. Define loading, error and empty states and a two-account authorization test. Exclude shared organizations and live payments until explicitly supported.
