Icons & Assets
Open Icon Libraries
Maintained by Multiple maintainers
Permissively licensed, actively maintained icon sets suitable for production use without per-seat licensing.
Why it matters
Icon licensing is a real legal risk in client work. These sets are MIT or Apache licensed, tree-shakeable, and available as code packages rather than pasted SVGs.
Key principles
- Pick one family and stay in it - mixing stroke weights and corner radii is the most common visual-system defect.
- Match icon stroke weight to your type weight; 1.5px stroke suits most 14–16px UI text.
- Never ship an icon-only control without an accessible name.
- Verify the licence before client delivery - Font Awesome and some Noun Project assets are not free for commercial use.
