Svg Repo is dope! There are tons of icons to use, all of them are high quality. I've been using it for all my web projects. I fully recommend it.
I like how the search is very useful and helps you find easily whatever you are into. Also, the possibility to edit colors and get the image in different formats is very helpful.
Amazing free and open icons. Literally best open licensed icons out there with nice format and extremely friendly interface to search for icons and collections of icons
Awesome product. It splits the icons into monocolor, multicolor and other categories. It is easy to find SVG files that I can use as icons while building any web or mobile app.
