View the raw HTML source of any URL — even pages you can't right-click 'View Source' on. The tool fetches through a CORS-friendly proxy and renders up to 50,000 characters of source for inspection.
Sometimes you need to see what's actually in the HTML — a meta tag, a tracking pixel, a piece of inlined JSON — but the page disables right-click, requires login, or is blocked by your network. A page snooper bypasses those minor inconveniences by fetching the page through a public proxy and displaying the source directly in your browser.
Paste any URL. The tool fetches the page server-side via a CORS proxy, formats the HTML for readability, and displays the first 50,000 characters in a scrollable code block. You can search the source with Ctrl+F to find specific tags, classes or strings.
Use it when learning HTML/CSS by inspecting how other sites build features, when verifying that a deployed change actually shipped, when checking a competitor's structured data, when auditing tracking scripts on a page, or when copying inspirational layouts.
Pair with View Source on your own browser — they should match. If they don't, your site is doing client-side rendering, which can hurt SEO. For dynamic JS-rendered pages, also check rendering with Google's URL Inspection tool in Search Console.
Yes — HTML source is publicly served to every visitor. Viewing it is no different from a browser's built-in 'View Source'.
The proxy fetches the raw HTML before any client-side JavaScript runs. Modern SPAs (React, Vue) often render most content in JS, which won't appear here.
Light, manual inspection is fine; automated scraping at scale violates most sites' Terms of Service. Use this tool ethically.
