Check now →What is inetutils.com?
inetutils.com is a free collection of internet diagnostic tools built for everyone — not just developers. Every tool gives you a plain-English answer to a common question about how the internet works, without requiring any technical background.
All network checks run from our servers, so results reflect real-world availability rather than your local connection. Encoding and generation tools (Base64, URL encode, password) run entirely in your browser and never send data anywhere.
The site is free to use, supported by advertising. No account or sign-up is required for any tool.
