Check DNS records, inspect HTTP headers, trace redirects, scan ports and validate your site configuration — all free, no signup required.
Webmaster tools are online utilities that help you inspect, debug and optimise your website. Unlike Google Search Console, these tools run directly in your browser with no account required — just enter a URL or domain and get instant results.
Common uses include checking DNS propagation after a domain change, verifying that HTTP security headers are correctly set, tracing redirect chains to find SEO issues and confirming that SSL certificates are valid and up to date.
