### Can Homarr run on a Raspberry Pi?

Yes, when the device uses a supported `linux/arm64` operating system. `linux/arm/v7` is not supported. See
[Prerequisites](/docs/getting-started).

### Can I use custom app icons?

Yes. Use a direct image URL, one of Homarr's icon sources, or upload an image. See [Icons](/docs/advanced/icons).

### Can I create widgets?

Yes. [Custom Widgets](/docs/management/custom-widgets) use server-side API requests and safe JSX. They can be written in
the workbench or created with an MCP-connected agent.

### Can Homarr be exposed to the internet?

Homarr supports authenticated and public deployments. Terminate HTTPS at a reverse proxy, keep Homarr updated, and grant
public board access only when anonymous viewing is intended. See [Board access control](/docs/management/boards#access-control)
and [Single sign-on](/docs/advanced/single-sign-on).

### Where are the logs?

Use **Management → Tools → Logs** for retained and live application logs. Container startup failures and older events are
available through the deployment platform, for example `docker container logs homarr`.

Use the browser developer console only for client-side failures. Review logs before sharing them because URLs and other
deployment details may be present.

### Why can Homarr not reach a service behind Gluetun?

Gluetun's firewall blocks traffic that is not explicitly allowed. Configure its
[`FIREWALL_OUTBOUND_SUBNETS`](https://github.com/qdm12/gluetun-wiki/blob/main/setup/options/firewall.md) for the relevant
LAN or Docker subnet, and use an address reachable from the Homarr container.

### Where do I report a bug or request a feature?

Use the [GitHub issue templates](https://github.com/homarr-labs/homarr/issues/new/choose). For community support, see
[Get in touch](/docs/community/get-in-touch).

### Can Homarr be used commercially?

Yes. Homarr is licensed under the [Apache License 2.0](/docs/community/license). Commercial users can support development
through [OpenCollective](/docs/community/donate).
