Demo Forge

Demo Forge is a video production tool that generates product demo videos from Playwright scripts and manual recordings.

Demo Forge converts Playwright scripts or manual Chrome extension recordings into professional MP4 demo videos. It synchronizes screen captures with narration, automatically zooming into clicks and displaying a synthetic cursor with natural motion. Users can edit videos in the browser, adding captions, background wallpapers, and custom zoom levels. The tool supports multiple voice providers, including local espeak-ng, Gemini, ElevenLabs, and Mistral, for narration. It is designed for developers who need to maintain up-to-date documentation and product demos without manual re-recording every time the user interface changes.
