HTML capture.

HTML capture records a web application's page as HTML and CSS rather than as an image, so the captured screen stays editable — text can be changed, elements hidden, data replaced — and renders crisply at any size.

HTML capture is the premium format in interactive demo tools. Its advantages are fidelity (real fonts, real responsiveness), editability (rename a customer in the capture without re-capturing), and the ability to build sandboxes on top. Its costs are complexity — captured pages carry scripts, fonts, and assets that must be sanitised and re-hosted — and price: most tools gate HTML to a mid or upper tier.

It also raises a security question: captured HTML is untrusted code and must be served from a separate origin inside a sandboxed frame, never from the application domain.
