feathericons/feather

Feather is a collection of clean, minimalist icons for websites and apps. Each icon is a simple line drawing, no fills, no gradients, designed to look elegant at small sizes. The full set covers common UI needs: arrows, social media logos, file types, weather symbols, communication icons, and more. You can browse everything at feathericons.com. For a vibe coder or founder building a web product: if your app needs icons and you do not want to pay for a design pack or spend time creating your own, Feather is a free, ready-to-use solution. Adding an icon to your page is as simple as one line of HTML, and you can control the size, color, and thickness to match your design. The icons are built as SVG files, a web-friendly format that stays crisp at any screen size, from tiny mobile displays to large monitors. You can use them directly in HTML, pull them into a JavaScript project as a package, or import them into design tools like Figma as a component library. Feather is free and open-source (MIT license), meaning you can use it in commercial projects without paying anything. It is a mature, widely-adopted project with nearly 26,000 GitHub stars and millions of monthly downloads. If you want icons with a more playful style, filled icons, or a larger variety, other libraries like Heroicons or Lucide (a community fork of Feather) are worth comparing, but Feather remains a reliable default for clean, professional-looking interfaces.
