>log in to commentHi DevHunt, I'm Micah, the founder of AtriumKit. I've been building software for many years, and every time I shipped something I wanted to show people its value without making them sign up first. The demo tools that did this well priced the parts I cared about for sales teams, so I built the version I wanted. The technical bit: the recorder saves each page's HTML next to its screenshot, so a renamed button or a new price is an edit in the editor instead of a new recording. The MCP server (https://app.atriumkit.com/mcp) lets Claude, ChatGPT or Cursor edit steps, translate and publish. Try this first: record one flow in your own app, then change a label on one of the captured pages. I'd love your honest take: would you rather have editable HTML captures, or screenshots that are simpler but need recording again?
AtriumKit is a Chrome extension plus a web app for interactive product demos and step-by-step guides.
The recorder doesn't only take screenshots. For each step it saves the page's HTML snapshot (gzipped, with images and fonts stored by hash) next to the screenshot. So the editor can change real text on a captured page, find and replace across a whole demo, or blur and hide elements after the fact. With a screenshot-only demo, a copy change means recording again. A captured page keeps its recorded layout, so a moved button or a new flow still means recording that flow again.
- Capture: a Chrome MV3 extension (WXT)
- App, player and storage: Cloudflare Workers, D1 and R2
- Video studio (beta): each scene is an HTML composition, rendered to MP4 in a sandboxed Cloudflare Container
- A remote MCP server (Streamable HTTP, OAuth 2.1), so Claude, ChatGPT or Cursor can edit demos
