# Other devices

> Use Magnitude from another computer, a tailnet, or a container.

By default the API is available only on the computer running Magnitude. Network access makes it available to other devices for inference. The app and model management stay on this computer.

## Turn on network access

1. Open **Settings → Network access** and turn it on.
2. Choose an **Address**. **All interfaces** serves every network this computer is on. Choosing one address serves only that network.
3. Copy the **API key**. Other devices send it with every request.
4. Copy the **Reachable at** URL.
5. Restart Magnitude when the **Restart required** notice appears.

The first time the service listens on a network, macOS or Windows may ask whether to allow incoming connections. Allow them.

## Another computer on your network

Use the **Reachable at** URL as the base URL and the API key as the key. The address is the one this computer has on your Wi-Fi or Ethernet network, such as `http://192.168.1.20:10100/inference/v1`. It can change when the computer joins a different network.

## Tailscale

Choose the Tailscale address under **Address** to serve only your tailnet. Other devices on the tailnet use `http://100.x.y.z:10100/inference/v1`. Magnitude also accepts its MagicDNS name, ending in `.ts.net`, so `tailscale serve` works without extra configuration.

## Containers

From a container on this computer, use `http://host.docker.internal:10100/inference/v1` with the API key. Network access must be on, because the container connects from its own address.

## Windows with WSL

An agent inside WSL reaches Magnitude either through loopback, with mirrored networking, or through the Windows host address, with network access on. See [Windows and WSL](/api/windows-wsl).

## Configure the app or agent

Use the **Reachable at** URL as the base URL and the API key as the key. For an app that is not a supported agent, the settings are the same as in [Other apps](/api/other-apps) with the network address in place of `127.0.0.1`.

**Connections** cannot configure a supported agent on another device, so write its configuration yourself. Each agent page shows the exact block under **Configuration**. Replace `ADDRESS` with the **Reachable at** address, `API_KEY` with the API key, and `MODEL_ID` with the model's exact ID; take the context window and output limit from the model's **Details**.

Codex and Claude Code route hosted models through Magnitude's gateway. From another device, only local models are available to them.

## Check the connection

From the other device:

```sh theme={"theme":{"light":"github-light","dark":"github-dark"}}
curl -H "Authorization: Bearer API_KEY" http://ADDRESS:10100/inference/v1/models
```

A model list means the connection works.

## Custom hostnames

Magnitude accepts requests addressed to its IP addresses, `localhost`, `host.docker.internal`, and `.ts.net` names. To reach it by another name, such as a reverse proxy or a LAN hostname, list the name under `network.allowedHosts` in the [configuration file](/reference/configuration-file).

## Troubleshooting

| Response                  | Meaning                                                                                                             |
| ------------------------- | ------------------------------------------------------------------------------------------------------------------- |
| Connection refused        | Network access is off, Magnitude is not running, or the chosen address does not include the network you are on.     |
| `401`                     | The request did not include the API key, or the key changed. Copy it again from Settings.                           |
| `403` on `/rpc`           | Application control is never available from other devices. Only inference is.                                       |
| `421 Invalid Host header` | The request used a hostname Magnitude does not accept. Use an IP address or add the name to `network.allowedHosts`. |
