# Web (Gateway)

The Gateway serves a small **browser Control UI** (Vite + Lit) from the same port as the Gateway WebSocket:

- default: `http://<host>:18789/`
- optional prefix: set `gateway.controlUi.basePath` (e.g. `/clawdbot`)

Capabilities live in [`docs/control-ui.md`](https://docs.clawd.bot/web/control-ui).
This page focuses on bind modes, security, and web-facing surfaces.

## Webhooks

When `hooks.enabled=true`, the Gateway also exposes a small webhook endpoint on the same HTTP server.
See [`docs/configuration.md`](https://docs.clawd.bot/gateway/configuration) → `hooks` for auth + payloads.

## Config (default-on)

The Control UI is **enabled by default** when assets are present (`dist/control-ui`).
You can control it via config:

```json5
{
  gateway: {
    controlUi: { enabled: true, basePath: "/clawdbot" } // basePath optional
  }
}
```

## Tailscale access

### Integrated Serve (recommended)

Keep the Gateway on loopback and let Tailscale Serve proxy it:

```json5
{
  gateway: {
    bind: "loopback",
    tailscale: { mode: "serve" }
  }
}
```

Then start the gateway:

```bash
clawdbot gateway
```

Open:
- `https://<magicdns>/` (or your configured `gateway.controlUi.basePath`)

### Tailnet bind + token (legacy)

```json5
{
  gateway: {
    bind: "tailnet",
    controlUi: { enabled: true }
  }
}
```

Then start the gateway (token required for non-loopback binds):

```bash
export CLAWDBOT_GATEWAY_TOKEN="…your token…"
clawdbot gateway
```

Open:
- `http://<tailscale-ip>:18789/` (or your configured `gateway.controlUi.basePath`)

### Public internet (Funnel)

```json5
{
  gateway: {
    bind: "loopback",
    tailscale: { mode: "funnel" },
    auth: { mode: "password" } // or CLAWDBOT_GATEWAY_PASSWORD
  }
}
```

## Security notes

- Binding the Gateway to a non-loopback address **requires** auth (`CLAWDBOT_GATEWAY_TOKEN` or `gateway.auth`).
- The UI sends `connect.params.auth.token` or `connect.params.auth.password`.
- Use `gateway.auth.allowTailscale: false` to require explicit credentials even in Serve mode.
- `gateway.tailscale.mode: "funnel"` requires `gateway.auth.mode: "password"` (shared password).

## Building the UI

The Gateway serves static files from `dist/control-ui`. Build them with:

```bash
bun run ui:install
bun run ui:build
```
