About these tools

All tools on this page are free, require no registration, and have no rate limits. They are built for webmasters, SEO specialists, marketers, and site owners who need a quick technical answer: where does this URL redirect, what DNS records does this domain have, when does the SSL certificate expire, who owns the domain by WHOIS, and is the site on the Russian RKN block list. Each tool runs in your browser and never sends your input to third-party services — passwords and QR codes are generated locally. Whether you are migrating a site, vetting a domain before a deal, monitoring your own assets, or building campaigns with UTM tracking, these tools cover the everyday tasks without forcing you to install dig, openssl, or curl.
