A Demo Tool That Works on Any Web App

August 20, 2026

Every demo tool claims to work with any web application. In practice capture quality varies enormously by product, and the differences show up on exactly the screens you most need to demo.

The good news is that this is cheap to test, and no comparison table will answer it for you.

What makes a product harder to capture

  • Canvas and WebGL. Design tools, maps, 3D views and charts drawn to a canvas are pixels to the browser, so structure-based capture cannot reproduce them.
  • Content behind hover. Menus and tooltips that only exist while the mouse is over them may not be present when the capture happens.
  • Aggressive lazy loading. Content that appears only when scrolled near can be missing from a snapshot taken too early.
  • Very long pages. A capture is one viewport; the rest of the page is a separate step.

Nothing gets installed in your product

The capture happens in your browser through an extension, not through an SDK or a script tag added to your application. That matters more than it sounds: it means no engineering ticket, no security review of a third-party script running in your product, and no risk to the app itself.

It also means you can demo a product you do not control — a partner's tool, a platform you integrate with, a competitor's public pages.

Two capture modes, because one is not enough

Screenshot capture is a picture: reliable everywhere, immune to the source site changing later. HTML capture keeps the real page structure, so text stays searchable, translatable and readable by a screen reader, and stays crisp at any size.

Demorta includes both on every plan including free, which is the point — an unusual screen can be captured as pixels while the rest of the demo keeps real text.

The ten-minute test

Record the single most awkward flow in your product — the data table, the modal, the chart — on a free plan, both ways. Then look at the result.

That answers the question no feature list can, costs nothing, and is worth doing before any subscription decision on any tool, this one included.

Frequently asked questions

Do I need to install code in my app to make interactive demos?
No. Capture happens in your browser through an extension, not an SDK or script tag, so there is no engineering ticket and no third-party script running inside your product. It also means you can demo products you do not control.
What kinds of screens are hard to capture?
Canvas and WebGL views such as design tools, maps and some charts, content that only exists on hover, and aggressively lazy-loaded sections. Screenshot capture handles most of these where structure-based capture cannot.
How do I know a demo tool will work with my product?
Record your most awkward flow on a free plan and look at the result. Demorta includes both screenshot and HTML capture on every plan including free, so testing both ways takes about ten minutes and costs nothing.
