Source Code Viewer
Source Code Viewer — paste a URL and get the answer in seconds.
This fetches a page server-side and shows you the raw HTML exactly as it was delivered, along with the status code, server header, size and any redirect chain. Useful when right-click is disabled, when you want the pre-JavaScript markup a crawler sees, or when you are checking what a page returns from outside your own network.
Frequently Asked Questions
How do I use the source code viewer?
Paste the URL into the box and press the button. The check runs on our server — not in your browser — because browsers are not allowed to read another site’s response, and the result appears within a few seconds.
Why does the source look different from what I see in the browser?
Because this shows the HTML as delivered, before any JavaScript runs. A site built with React or Vue may send an almost empty shell and build the page in the browser — which is exactly what a search engine crawler sees first, and precisely why viewing the raw source is useful.
Why does this one need a server when your other tools do not?
The browser’s same-origin policy stops JavaScript reading a response from another website, and a browser has no access at all to a TLS certificate chain. Almost every tool on this site runs entirely on your device; these few genuinely cannot, so they run on ours instead.
Do you store the URLs I check?
No. The request is made, the answer is returned to you, and nothing about it is kept.
Can I check a site that is not mine?
Yes — everything here reads only what the site already serves publicly to any visitor. Nothing is scanned, probed or attacked; it is the same information your own browser fetches when it loads the page.
