About
Free webmaster and developer utilities. Run by Aleksey Krivoshein.
CyberTools is run by Aleksey Krivoshein (Dr.Slon). Email: slon.code@gmail.com.
The site is a set of working utilities, grouped in eleven sections: network, SEO, images, documents, text, developer tools, security, calculators, unit converters, media, and small utilities. Each tool has its own page; the most used ones also have a detailed how-to in the blog.
Converters, hashes, generators, and text utilities run in the browser. DNS, SSL, ping, and HTTP checks send the server only the host or URL you type. Details are in the privacy policy.
A captcha sits on the heavy outbound checks. Light lookups such as DNS open immediately.
