Product demo videos that re-record when your UI changes

3 followers

Demo videos go stale every time your UI changes. DemoForge makes a demo a file: a short flow.json of Playwright steps, each with one line of narration. One command records your app with auto-zoom on every click, a smooth cursor and a voiceover that sets the pace. Fine-tune zooms, cuts and captions in a browser editor, then export an MP4. UI changed? Run it again. Claude Code can write and record the flow for you. Open source (MIT), runs locally, free voice included.
