# Live VLM WebUI
> Real-time Vision Language Model interaction with webcam streaming
Live VLM WebUI is a universal web interface for real-time Vision Language Model (VLM) interaction and benchmarking. It enables you to stream your webcam directly to any VLM backend (Ollama, vLLM, SGLang, or cloud APIs) and receive live AI-powered analysis. This tool is perfect for testing VLM models, benchmarking performance across different hardware configurations, and exploring vision AI capabilities.
The interface provides WebRTC-based video streaming, integrated GPU monitoring, customizable prompts, and support for multiple VLM backends. It works seamlessly with the powerful Blackwell GPU in your DGX Spark, enabling real-time vision inference at impressive speeds.
**Outcome**: You'll set up a complete real-time vision AI testing environment on your DGX Spark that allows you to:
- Stream webcam video and get instant VLM analysis through a web browser
- Test and compare different vision language models (Gemma 3, Llama Vision, Qwen VL, etc.)
- Monitor GPU and system performance in real-time while models process video frames
- Customize prompts for various use cases (object detection, scene description, OCR, safety monitoring)
- Access the interface from any device on your network with a web browser
