After you have successfully installed ComfyStream by following the installation guide, you can run your first AI workflow.

​
Prerequisites

Download example workflows from the ComfyStream GitHub repository to test your setup.

​
Accessing ComfyStream UI

When you click the ComfyStream node and select ComfyStream UI Preview in ComfyUI, it will open a window that looks similar to the image below:
comfystream-ui-dialog-box.png
If you prefer to run workflows in a new tab rather than inside ComfyUI, click Open ComfyStream UI from the ComfyStream Menu. This will open a similar dialog box in a new browser tab.
Opening the UI will ask for permission to access your video and audio so it can stream your webcam and microphone. You need to provide access to use ComfyStream.

​
Running Your First Workflow

ComfyStream currently supports only the API workflow format. To export a workflow in this format, use Workflow > Export (API) in ComfyUI. Support for the native ComfyUI format is under development and will be available in a future release.
1

Select your workflow

In the ComfyStream UI, click Choose files and select one of the previously downloaded workflows.
2

Start ComfyStream

Click Start Stream to start the workflow. Once the stream starts, you will see Starting Stream.. at the bottom of the page. Depending on the workflow complexity, it may take some time to start. Please wait patiently.
3

Enjoy your stream

Once the stream starts, you will see the AI effects being applied in real-time.

In this example preview, comfystream UI is accessed from inside comfyUI and the workflow is selected from local storage.

To see the similar preview, copy the example-workflow.json to local storage and launch it from comfystream UI as shown above.

​
Troubleshooting

For advanced users, you can check the logs in the ComfyStream server to see if everything is loading properly without any major errors.

ComfyStream Server Logs.

The ComfyStream server logs are in the ComfyUI log window. Open the bottom panel using the Toggle Bottom Panel button at the top-right of the interface.
If you encounter the following error when starting a stream on RunPod:
Error proxying offer: Cannot connect to host localhost:8889 ssl:default [Connect call failed ('127.0.0.1', 8889)]
Please check the ComfyStream Server Settings to ensure ComfyStream is running on host 0.0.0.0 when using RunPod. The default Stream URL in ComfyStream UI (http://127.0.0.1:8889) is correct when using the RunPod template.
