Frequently asked questions

Do I need an account to use these tools?

No. Every tool on this site works without signup.

Why do some checks show limited results?

Browser security rules limit what a web page can read from other sites. This site reports those limits honestly instead of inventing a complete result.

Can I check a private or internal site?

No. These tools check public domains and URLs reachable from your browser. Internal sites need a check from inside your own network.

Are my lookups stored?

This site does not store your lookup inputs on its own server. Public APIs you query receive the domain or IP you enter for that single request.
