Frequently asked questions
Do these tools send network requests?
Some tools (DNS lookup, HTTP header analyzer) make client-side requests to resolve the data you ask about. Your input never goes to our servers.
Can I generate a sitemap for my site?
Yes — the XML Sitemap Generator produces standards-compliant sitemap XML you can upload to your server or submit to search engines.
