Icônes is an amazing icon resource site. There are tens of thousands of free-to-use icons which are easy to browse and find. I guess it’s like an alternate UI to Iconify, making it ultra-fast to get the icon in a format you want it in, like a quick download of SVG or PNG, copying to your clipboard in one of those formats, or as a basic component in many of the most popular frameworks.
I still love The Noun Project a bunch, but it costs bucks, doesn’t seem to have innovated much (like it doesn’t have as many nice exporting options), and doesn’t group icons as well.
Jeez, Anthony Fu has done some incredible open-source projects!
Oh, and hey, if the idea of exporting to framework components is appealing to you, check out iconbundler which can take a whole bunch of them and do it for you right from the browser. I tend to use SVGR, though, to automate it.
