# Apps

Deploy applications and persistent services.

Canonical page: https://beeuni.ai/docs/apps

Apps host static sites, servers, workers and databases. Each App has a stable URL. A release contains its code and configuration; a failed deployment does not replace the active release.

Server Apps run machines. Volumes retain data across releases; a machine’s root disk resets on replacement. Use a volume for database files and other persistent data.

Apps availability depends on your project. Open Customize → Apps to see available features.

App previews keep loading when you move between project pages. Each App can
declare its display settings and expose connection examples for your code.
Use the App's stable URL when connecting an external product.

```bash
beeuni apps list
beeuni apps show main
beeuni apps connect main
beeuni apps launch --template convex --slug main
beeuni apps deploy dist --type static --spa
beeuni apps machines main
beeuni apps volumes main
```

Connect applications with `uses` and use the connection examples shown by `beeuni apps connect`. Keep administrative credentials out of client-side code.

Running resources consume account credits. Check Billing and Usage for your balance. Apps do not have a separate monthly budget.

Back up important data. Restoring a volume snapshot discards later changes. Deleting a volume permanently removes its data.
