The tutorial covers the full stack: a FastAPI WebSocket backend streaming JPEG frames to/from the model, a React frontend using canvas APIs and createImageBitmap for GPU-accelerated rendering, Clerk for authentication, and ChargeB (sponsor) for subscription billing with tiered plans. User metadata in Clerk stores subscription status and usage seconds, eliminating the need for a separate database. Video recording via CanvasCaptureStream and WebM export is also included. ## Full article daily.dev links to this article rather than hosting it.
