Create product demo videos with your coding agent.
Describe the demo you need, and your coding agent explores the web app, records the flow, adds cursor movements and zooms, then renders the finished video.
Actively developed. Commands and file formats may change between minor releases.
Shipping features is fast. Recording demos usually isn't.
You have to plan the walkthrough, record a clean take, edit it, and package everything for sharing. Then the product changes and the video is already out of date.
Demo Recorder lets you automate this through your coding agent. Tell it the flow you want, and it walks through the product, records the demo, and renders the video. It can also record a feature after an agent finishes building it, making the result easier to review without manually retracing the flow.
Common use cases:
- demos for product updates and release posts
- short walkthroughs for documentation and tutorials
- video previews of features built by coding agents
- visual context for pull requests and handoffs
- clips for launch posts and social media
- internal walkthroughs for teammates and stakeholders
Current capabilities:
- explore a web application and prepare the recording flow
- hand control back when login or CAPTCHA is required, then reuse the authenticated session
- avoid destructive or unclear actions unless explicitly requested
- record navigation, clicks, explicit keyboard shortcuts, scrolling, and interface changes
- add smooth cursor movement, click feedback, Screen Studio-style key overlays, zooms, and trim unused parts
- save the walkthrough as a reusable plan that can be adjusted and recorded again
- render the finished video as an MP4
- Node.js 22 or newer

Install the skill:
npx skills add noice-tech/demo-recorderThen ask your coding agent for the demo you want:
Create a short demo of banger.show. Start on the home page, open the music visualizer, and show it in action. Keep it smooth and under 25 seconds.
On first use, the skill asks before installing its pinned runtime in a user cache. It also asks separately before downloading Playwright Chromium if it is not already available.
Or ask it to record the result of a development task:
Implement the new sharing flow, then record a short demo showing how it works.
0.2.0 introduces a simplified, project-scoped workflow: persistent exploration, reusable plans with expected states, fresh-browser rehearsal, capture, and step-anchored zooms and trim.
Playwright Chromium is the default for exploration and recording. When the user requests their existing Chrome, Playwright CDP supports exploration only.
Future work includes attached real-browser recording and additional export formats.
Contributions, bug reports, and real-world examples are welcome. If you want to work on the project, start with the development guide.
For larger changes, opening an issue first is the easiest way to discuss the approach and avoid duplicated work.
