Https://publicwww.com/ is a great tool for this, though the size of its index leaves a lot to be desired. Still, for enumerating well-SEO'd homepages that use a certain tech stack, it's quite useful! - Source: Hacker News / 10 months ago

You can also use the PublicWWW service. It helps you to find snippets and key words in the HTML, JS, and CSS webpage code.
