feat: add Open WebUI AI chat integration and widget
Adds a new "openWebUi" integration kind (under a new "ai" category) and an AI Chat widget for chatting with models served by Open WebUI. - Integration: Bearer API key auth, model list, native chat history CRUD, and token-by-token streaming chat completions (SSE). - Widget: in-input model picker, streaming responses, and an in-widget history panel. Reconstructs conversations from Open WebUI's message tree with a flat fallback. - Streaming is delivered over the WebSocket subscription link. - Adds integration and widget documentation.

[Open WebUI](https://openwebui.com/) is a self-hosted AI chat interface that aggregates multiple LLM providers (Ollama, OpenAI-compatible APIs, and more) behind a single API. Homarr connects to it so you can chat with your models directly from your dashboard.
|
||||
|
||||
### Widgets & Capabilities

### Adding the integration
|

|
||||
<AddingIntegration />
|
||||
|
||||
:::info URL configuration
|
||||
Use the root URL of your Open WebUI instance, for example `http://localhost:3000`. Homarr calls the Open WebUI API under `/api` automatically.

The AI Chat widget lets you chat with AI models served by Open WebUI directly from your dashboard. Responses stream in token-by-token, you can pick any model your Open WebUI instance exposes (Ollama, OpenAI, and other configured providers), and you can browse and reopen your Open WebUI chat history.

### Configuration
|

|
||||
<WidgetConfig configuration={openWebUiWidget.configuration} />
|
||||
|
||||
### Features
|
||||
|
||||
| Feature | Description |
|
||||
| ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| **Model picker** | Lists every model exposed by Open WebUI's `/api/models` endpoint, selectable from the chat input. The first model is selected by default. |
|
||||
| **Streaming responses** | Assistant replies stream in live as they are generated. |
|
||||
| **Chat history** | Browse and reopen previous chats. New conversations are saved back to Open WebUI. |
|
||||
|
||||
### Notes
|
||||
|
||||
- The widget uses a single Open WebUI integration.
|
||||
- Conversations are stored in Open WebUI itself, under the account that owns the API key, so they also appear in the Open WebUI app.
