Heroicons

Heroicons is a comprehensive collection of 316 free SVG icons designed for modern web and application development. The icons come in four distinct styles: outline (24x24 with 1.5px stroke), solid filled versions, mini (20x20), and micro (16x16) variants, providing designers and developers with flexible options for different interface needs. All icons are hand-crafted by the makers of Tailwind CSS and available under the MIT license, making them free for both personal and commercial projects without attribution requirements.

The library stands out for its clean, consistent design aesthetic and practical utility. Each icon is delivered as SVG code that can be easily copied and pasted directly into projects, and official React and Vue component libraries are available for framework-specific integration. The team also provides a Figma community file, allowing designers to incorporate the icons directly into their design workflow alongside development implementation.

Web developers and UI designers benefit most from Heroicons, particularly those working on projects that require a cohesive visual language without the overhead of creating custom icons from scratch. Product teams can use these icons to maintain design consistency across web applications, mobile apps, and marketing materials, while individual developers can quickly prototype interfaces with professional-grade visual elements that scale perfectly at any size.
