# Preview Workflows on a Webcam Stream from the Web Editor
You can now run Workflows on a webcam stream from the Roboflow Workflows web editor. This feature is useful for testing Workflows as you develop them. This is available in addition to testing a Workflow on image and video files, RTSP Streams, and USB Devices.
The FPS at which the preview runs will depend on the complexity of your Workflow; smaller object detection models, for example, should run in real time; larger object detection models or foundation models like SAM 3 will be slower and will thus run at a low FPS.
To test your Workflow on a webcam, click "Test Workflow" in the Workflows web interface, then select "Webcam" as your image input. You can then select a webcam to use. Your browser will ask you to give permission to use the webcam. Then, you can run your Workflow.
It will take several seconds for the preview to be available, after which point you will be able to see the results from your Workflow.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.roboflow.com/changelog/explore-by-month/november-2025/preview-workflows-on-a-webcam-stream-from-the-web-editor.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
