What is iamroot.tech?

iamroot.tech is a set of advanced and detailed online available tools centered around admin, development and GUI/UI/UX tasks.

The need for this grew out of my day job as a fullstack developer and systems administrator. I needed a set of fast and reliable tools, with advanced options for me to tweak, clear and understandable results, and without having to deal with tons of ads and useless info added, just to make it look fancy.

The tools have been extremely useful to me , and I hope they will serve you as well.

Best regards
Flemming
