In simple English
When you change your website, your product videos and screenshots go out of date instantly. Fixing them by hand takes hours of tedious recording and editing. This tool runs a web browser for you, clicks through your app, and makes fresh videos and pictures automatically. You can run it on your own computer or set it to run inside your code deployment pipeline. It costs nothing to use, and all your files stay on your machine.
What it is
AutoDemo is a command-line tool written in TypeScript that controls a real browser to capture video, interactive HTML walkthroughs, and cropped images of your web app. It can drive the browser using simple YAML configuration files, or use an artificial intelligence key to figure out what to click from a plain English sentence.
What it is good for
Solo builders and small teams who want to keep their landing page videos, documentation screenshots, and pull request demos up to date without paying for expensive demo software.
- Generates videos, interactive web walkthroughs, and named image captures from one command.
- Keeps your demos fresh by running automatically every time you update your code.
- Works with or without artificial intelligence keys using simple step-by-step configuration files.
- Requires the Bun runtime and Node.js toolchains installed on your system.
- Needs FFmpeg installed on your machine to export MP4 video files.
- Running AI-driven demo generation requires your own paid API key for a provider like OpenAI or Anthropic.
