List
Icons, illustrations & assets
High-quality assets you can actually use, plus the best places to find more. Licences checked, no dead links.
1.

Lucide
Huge, consistent open-source icon set — the modern Feather
Curator note
The default recommendation. Huge, consistent, MIT licensed, and available for every framework. The community fork of Feather that outgrew the original.
2.
Phosphor Icons
Flexible icon family with six weights for every context
Curator note
Six weights in one family, which is the thing you didn't know you needed until you're trying to make a thin icon sit next to bold text.
3.
ICONES
All popular icon sets, one framework
Curator note
The mothership — search across 200,000+ icons from every open set at once, then copy exactly the format you need.
4.
Tabler Icons
5,000+ free MIT-licensed icons on a consistent grid
Curator note
5,000+ icons on a consistent 24px grid. Particularly strong for dense, admin-style interfaces where you need something specific and slightly obscure.
5.
Radix Icons
Crisp 15×15 icons designed for dense interfaces
Curator note
Small, crisp, and designed for 15×15. The right choice when your UI is dense and most icon sets look bloated in it.
6.

Recraft
Generate real vectors and icon sets in a style you can pin and reuse
Curator note
When the set you need doesn't exist. Real editable vectors with a pinned style, so twenty generated icons actually look like siblings.
7.

LottieFiles
Lightweight animations that run natively on web and mobile
Curator note
Lightweight animation that runs natively rather than as a video file. The default for loading states, empty states, and small moments of feedback.
8.

Blush
Illustrations for everyone
Curator note
Illustration you can recolour and recompose, which is the difference between an asset library and a folder of pictures you can't change.
9.

Storyset
Customisable illustrations you can recolour and animate
Curator note
Customisable illustrations with animation options. Good breadth for marketing pages and empty states.
10.

Undraw
Open-source illustrations for any idea
Curator note
The one everyone uses — which is both its strength and the reason to change the accent colour before you ship it.
11.
Simple Icons
Brand icons for thousands of popular services
Curator note
Brand marks for thousands of services, kept current. Saves an hour every time you build an integrations page.
