For web pages, you could use Puppeteer (headless Chrome) to save to PDF, then convert the PDF to SVG. You'd need to do some coding to set the screenshot up first so it's posed the way you want though e.g. hide elements you don't need to show and replace text/numbers with mock content. The screenshot I'm using here for a landing page isn't going to be generated often enough that it's worth automating.
