What is DOM capture?
Definition
DOM capture is a demo-creation technique that records the actual HTML, CSS, and structure of a web page; producing a pixel-perfect, interactive replica instead of a flat screenshot.
When a tool captures the DOM (Document Object Model), it stores the page as living markup rather than pixels. Text stays selectable and razor-sharp at any zoom level, layouts remain responsive, and hover states can still fire; the demo feels like the product because structurally it is the product.
Screenshot-based demos, by contrast, are image slideshows with clickable dots. They blur when zoomed, break on mobile widths, and scream 'recording' the moment a viewer looks closely. This is why DOM capture is the most gated feature in the demo-software market: Storylane holds it at $500/mo, Supademo at $350/mo, Arcade at Enterprise-only. Mirage includes it on the free plan.
Why it matters
Capture fidelity is the single biggest quality difference between demo tools. Buyers can tell within seconds whether they're clicking a real interface or a picture of one; and the real one converts.
Example
A demo captured via DOM snapshot lets a viewer zoom to 200% on mobile and still read crisp text in the pricing table; the same demo as screenshots would be a blur.
Common questions
Is DOM capture the same as HTML capture?
Yes; vendors use the terms interchangeably. Both mean the demo stores real markup and styles rather than images.
Which demo tools include DOM capture on cheap plans?
As of mid-2026: Mirage includes it free; Navattic includes it from its $500/mo Base tier; Storylane gates it at Growth ($500/mo); Supademo at Growth ($350/mo); Arcade reserves it for Enterprise.
