Example result — this is what a check looks like. Enter your own address above to replace it.

One check covers your whole site
Security, speed, DNS and email, AI and search visibility, content, and domain expiry — all from one address, free and unlimited. The pages below go deeper on a single part of it.
Free website checks — the whole tool, not a sample
Unlimited scans, no signup, no account, no card. Every check runs in full, every time; nothing is held back for a paid tier, because there isn't one. Most free website checkers show you a score and charge for the reasons — this one gives you the reasons. Also free here: an AI visibility check that reads your robots.txt and tells you whether ChatGPT, Claude and Perplexity can actually reach your pages.
