Iconoir

Iconoir is an open-source library of 1,600+ SVG icons drawn on a 24px grid, free with no paid tier or email sign-up. It ships as an npm package with official React, React Native, Vue, Flutter and Swift libraries, a CSS version and a Figma community file, and it is built into Framer's insert menu. Icons default to the current font size and display inline-block, so they line up with surrounding text without extra styling.
