# App Management

Open **Deployments** and select an app to manage it. Each hosted app has **Deployment**, **Logs**, **History**, **Custom Domain**, and **Settings** pages.

```python exec
import reflex as rx
```

## Deployment

The **Deployment** page shows the live URL, status, current deployment, domains, backend URL, app preview, RAM, CPU, Reflex and Python versions, and regions.

Use **Stop app** to stop the running deployment. The app becomes unavailable until it is deployed or started again.

For a stopped app, select **Start app** to restart its latest deployment.

```python eval
rx.image(
    src="https://web.reflex-assets.dev/docs-preview/hosting/deployment.webp",
    alt="A running deployment with its app preview and resource summary",
    class_name="rounded-md h-auto mb-4",
    border=f"0.81px solid {rx.color('slate', 5)}",
)
```

```md alert info
# CLI commands to stop or start an app
`reflex cloud apps stop [OPTIONS] [APP_ID]`

`reflex cloud apps start [OPTIONS] [APP_ID]`
```

## Logs

Use **Logs** to search runtime output and filter by order, timezone, time range, and region. See [Logs](/docs/hosting/logs/) for the UI and CLI workflows.

## History and Rollback

Every deployment appears under **History** with its deployment ID, state, actor, and timestamp. **Current** identifies the live deployment; older entries are **Historical**.

```python eval
rx.image(
    src="https://web.reflex-assets.dev/docs-preview/hosting/history.webp",
    alt="Current and historical deployments in the History page",
    class_name="rounded-md h-auto mb-4",
    border=f"0.81px solid {rx.color('slate', 5)}",
)
```

Select a deployment ID to open its detail page. It shows the deployment note, domains, backend URL, Reflex and Python versions, deployment statistics, and build logs.

### Roll back to a previous deployment

A rollback redeploys a previous deployment's stored image and makes it current without rebuilding from source:

1. Open **History**.
2. Find a historical deployment with an enabled **Rollback deployment** action.
3. Review the **Current** and **Rollback target** deployment IDs in the confirmation dialog.
4. Select **Rollback**. The app briefly restarts while Reflex switches versions.

```python eval
rx.image(
    src="https://web.reflex-assets.dev/docs-preview/hosting/rollback_dialog.webp",
    alt="Rollback confirmation comparing the current and target deployments",
    class_name="rounded-md h-auto mb-4",
    border=f"0.81px solid {rx.color('slate', 5)}",
)
```

Rollback requires permission to deploy. It is available only when Reflex still has a compatible image for the current hosting provider and hosting mode. Wait for any active deployment to finish first.

```md alert info
# Projects with deployment approval
Rollback is disabled while **Require approval to deploy** is enabled. Deploy the desired version through the normal approval workflow instead.
```

Use the same workflow from a historical deployment's detail page.

CLI equivalents:

```bash
reflex cloud apps history <APP_ID>
reflex cloud apps rollback <DEPLOYMENT_ID> --app-id <APP_ID>
reflex cloud apps build-logs <DEPLOYMENT_ID>
```

### Add deployment notes

Add a note at deploy time to make History easier to scan:

```bash
reflex deploy --description "Update checkout validation"
```

On a deployment detail page, select **Edit** next to **Notes** to update it. From the CLI, run:

```bash
reflex cloud apps describe <DEPLOYMENT_ID> \
    --app-id <APP_ID> \
    --description "Update checkout validation"
```

Pass an empty description to clear the note.

## Custom Domain

Use **Custom Domain** to add a domain, copy the required DNS records, and check verification. See [Custom Domains](/docs/hosting/custom-domains/).

## Settings

**Settings** contains five pages:

- **General**: app name, description, hosting provider, and app ID.
- **Scale**: current CPU, memory, and VM type. See [Machine Types](/docs/hosting/machine-types/).
- **Regions**: current deployment regions and the option to add another region. See [Regions](/docs/hosting/regions/).
- **Secrets**: app environment variables and Sensitive mode. See [Secrets and Environment Variables](/docs/hosting/secrets-environment-vars/).
- **Danger**: permanent app deletion.

```python eval
rx.image(
    src="https://web.reflex-assets.dev/docs-preview/hosting/settings.webp",
    alt="General settings for a hosted Reflex app",
    class_name="rounded-md h-auto mb-4",
    border=f"0.81px solid {rx.color('slate', 5)}",
)
```

Switching the hosting provider stops the app on its current provider. Redeploy it after the switch to bring it up on the new provider.

Delete an app from **Settings > Danger**, or from the CLI:

```bash
reflex cloud apps delete <APP_ID>
```

Deletion is permanent. Confirm the app ID before running the command.
