A few websites I've got saved in my bookmarks

I can't promise these are tracker-free. Be safe on the internet, and use an ad/tracker blocker

I use https://mynoise.net/ way too much. I really love how the website is setup, and the monetization method is very non-intrusive. It has at least 100 different types of noises, from white/pink/grey noise, to recorded/perfectly looped rain sounds. The sounds are very high quality, and different parts of the noise sample audio can be adjusted.

https://radio.garden Allows you to listen to 100s of live radios using the internet with the click of a button

https://fyrean.itch.io/bgbye-background-remover Is a seriously robust background removing tool i found on Itch.io

https://zty.pe/ Is a fun typing game which allows you to import your own websites

https://keyboard-test.space/ Really good keyboard tester

https://ohmygit.org/ Great tool for learning how git works

The Typing Game is really fun, have to bookmark that. The Git learning game is also really Intuitive, might need to Introduce it to the Coding Course People at the non Profit I volunteer at.
