Linewright Icons

Linewright Icons is a large open-source outline set: 2,400 icons drawn on a 24px grid with a 1.5px stroke, rounded joins and a 2px safe zone. The stroke width is adjustable in the Figma components and as a prop in the React and Vue packages, and an icon font is included for older stacks.

It's the set we recommend to front-end developers who need one consistent family for a whole product and don't want to mix three libraries. Everything is MIT licensed, so you can ship it in commercial apps without credit. The caveat: brand and logo icons are not included, and a few of the newest icons in the finance category are still marked as beta.
