Online tools like that are best improved by making them into VS code plugins. To compare text outside of Git I open Meld and paste it in. Timestamp conversion? SwissKnife in VS code. Make a UUID? Command pallete has me covered! The all-in-one online tools like CyberChef linked below are the most interesting, that way you don't have to have to dig around for different ones. But simple utils should not be hard to get to or need internet when VS code has more convenient options. Online tools are great for casual users who don't have VS code or want it though.
