Bootstrap Icons

Bootstrap Icons is the official icon library for Bootstrap, the world's most popular CSS framework, launched by the Bootstrap team in 2020. With 2,000+ free MIT-licensed icons designed to integrate seamlessly with Bootstrap-based sites, this is the canonical icon library for the millions of websites + applications built on Bootstrap. The pitch is direct: if you're using Bootstrap, Bootstrap Icons is the natural icon library — designed by the same team, optimized for Bootstrap's design language, includes integration documentation, and free under MIT for any use. For Bootstrap users, this is essentially the default choice with no compelling reason to look elsewhere unless you need icons not in the library. What makes Bootstrap Icons distinctive is the Bootstrap ecosystem integration + free MIT license + active maintenance by the Bootstrap team. Bootstrap dominates CSS frameworks (used on 20%+ of all websites). Most Bootstrap users default to Bootstrap Icons for ecosystem coherence. The icons are designed by Mark Otto (Bootstrap creator) + the Bootstrap team specifically for Bootstrap's aesthetic — slightly more traditional + utility-focused than Tailwind Labs' Heroicons. The MIT license + free pricing make it accessible to any Bootstrap project regardless of budget. The core feature set: • **2,000+ icons** — comprehensive coverage for common UI needs • **MIT license** — free for commercial + personal use, no attribution required • **SVG format** — vector files for any context (CSS, HTML, image editors) • **Bootstrap integration** — designed to match Bootstrap's design language + sizing system • **Web font option** — Bootstrap Icons font for traditional CSS class workflow • **Individual SVG files** — download specific icons as standalone SVGs • **CSS class API** — `<i class="bi bi-house"></i>` style usage • **React component support** — via community-maintained react-bootstrap-icons package • **Search + filter** — find icons by name + category on icons.getbootstrap.com • **Categories** — organized by type (arrows, communication, devices, etc.) • **Consistent design language** — single team maintains visual coherence across library • **Open-source GitHub** — MIT-licensed source with community contributions • **NPM package** — `bootstrap-icons` for easy installation • **Recent updates** — regular new icon additions maintained by Bootstrap team • **Accessibility-conscious** — proper SVG markup for screen readers • **Customization-friendly** — CSS-styleable colors + sizes For Bootstrap users + traditional web developers + WordPress sites the use cases: • **Bootstrap-based sites** — default icon choice for ecosystem coherence • **WordPress themes** — many Bootstrap-themed WP sites use Bootstrap Icons • **Admin dashboards** — Bootstrap dominates admin templates; icons integrate naturally • **Internal tools + admin UIs** — Bootstrap + Bootstrap Icons common stack • **Documentation sites** — technical docs using Bootstrap styling • **CSS-based icon workflow** — for users preferring CSS class approach vs React components • **Cross-framework projects** — works in any HTML context (vanilla, jQuery, React, Vue) • **Beginner-friendly icon adoption** — simpler than complex SVG component setups • **Educational + learning materials** — Bootstrap is widely taught; icons match curriculum • **Legacy CSS framework projects** — Bootstrap 4/5 sites continue using these icons The pricing is completely free under MIT license. No premium tier exists — all 2,000+ icons free for commercial + personal use without attribution. The Bootstrap team monetizes via Themes (Bootstrap Themes marketplace) + sponsorship rather than icon library. Compared to Heroicons (free, 300+), Tabler Icons (free, 5K+), Lucide (free, 1500+), Bootstrap Icons sits in the middle (2K+) at free MIT pricing — competitive coverage with framework-specific design. Where Bootstrap Icons wins clearly: official Bootstrap ecosystem integration is meaningful for the 20%+ of websites using Bootstrap; designed to match Bootstrap's design language naturally; free MIT license at premium quality from Bootstrap creator; CSS class API + web font support traditional Bootstrap workflows; active maintenance by Bootstrap team ensures continued relevance; comprehensive 2K+ icons cover most UI needs; multi-framework compatibility (vanilla, jQuery, React, Vue) suits diverse projects. Where it loses: design style is Bootstrap-aligned which may not fit non-Bootstrap aesthetics (more utilitarian than Tailwind's modern minimalism); smaller library than Tabler Icons (2K vs 5K+) for niche needs; less mindshare among modern React + Tailwind developers (who default to Heroicons/Tabler); CSS web font approach increasingly considered legacy vs modern SVG components. My take: for Bootstrap users + traditional CSS framework projects + WordPress themes using Bootstrap — Bootstrap Icons is genuinely the right default and the ecosystem integration justifies preference over alternatives. For modern React + Tailwind projects, Heroicons or Tabler more naturally fit the modern stack. For maximum icon variety in free library, Tabler (5K+). For Bootstrap-specific projects in 2026, Bootstrap Icons is the canonical default + works without friction. Most Bootstrap users will land here naturally without considering alternatives, which is appropriate — the framework + icon library pairing makes sense.
