Here's another hidden gem of open source icons: https://phosphoricons.com/

very stylish!

P.S. I tried to sell stock icons in early 2000s, hehe. Hard to imagine that now. So many excellent open source vector icons.

This is very nice. I mostly use Material Design Icons [1] now, but lately they feel too crude to me, and these Iconoir icons are very lightweight.

Still, MDI are very consistent and have a lot of icons now, I think over 4000 last time I checked. Probably, the biggest free set out there.

My go-to font is heroicons[0], but this looks really nice. The entire set does have a consistency that is often missing in free offerings.

Heroicons is nice (especially when used with Tailwind/TailwindUI) but unfortunately it’s too small a collection. I almost always have to supplement with e.g. FontAwesome.

I switched to community-maintained ForkAwesome: https://forkaweso.me/Fork-Awesome/

Here is an aggregator site I found a while back. Very useful.

Thanks, this is very helpful, as I can see all the icons in a single click, without having to go to each github repo for each packages.

And it's on iconify! https://icon-sets.iconify.design/iconoir/

I'm wondering about the MIT license for icons: say you print these icons on physical objects, e.g. beach balls, do you have to include a copy of the copyright notice and permission notice somewhere on them, or how does it work?

I think the MIT license doesn't "infect" the product. You put the license in the software that creates the, say, PDF. But once printed the license doesn't apply.

Imagine having to slap the Latex license to every work you do with that software.

Confused by this exact question. Similarly, can they be used in a closed source app or website? Where/how do you include the license?

In a closed source app, you can make a 'credits' button that lists the various MIT/BSD licenses that you're utilizing. On a website, you might find it under 'legal' or 'about' etc.

Probably with a sticker on the object, pointing to a URL containing the full list of licenses.

For my latest projects I've been using React icons: https://react-icons.github.io/react-icons/

It includes many OSS sets and is a breeze to use (with React, obviously)

This is great

Generally, unicode special characters and emoji are enough.

It seems there have been one new unicode version per year since 2014.

I wonder how difficult it is to render emoticons with colors.

I personally like Noun Project. http://nounproject.com

They got rather heavy-handed in recent times, though: all icons are behind a registration wall and an anti-scraping ToS even if the author declared them to be e.g. CC-BY, so while the result is royalty-free I wouldn’t count is as open source. (The website doesn’t call it such, either, so there’s that.)

Great resource of open source icons, wonder how these folks make money ?

A few commenters here mentioned they work on creating minimized versions of svg icons. They published a few github pages in this regard. Would love to see them mentioned again.

"designed on a 24x24 pixels grid"

They're vector-based, so how are pixels involved?

I guess it means the graphics are aligned on a 24x24 grid where applicable for visual unity.

It means they are designed to be rendered at approximately 24x24 pixels.

Anyone here use iconair and their thoughts on it?
