How to choose
- Match style to product: Minimal apps → Feather/Tabler; Material-focused → Material Icons; design systems → Remix or Heroicons.
- Preferred format: For React/Vue, pick SVG-first sets; for legacy sites, icon fonts like Font Awesome or Ionicons can help.
- Licensing needs: MIT and Apache 2.0 are permissive. CC BY requires attribution—avoid if you can’t provide it.
- Performance: Use optimized SVGs or subset icon fonts; serve sprites or inline only used icons.
- Customization: SVGs are easiest to recolor/scale; check viewBox and stroke/fill consistency.
Quick integration tips
- Inline SVG components for React/Vue to allow props for size/color.
- Use an icon library CDN or npm package for rapid setup, then tree-shake unused icons.
- Optimize SVGs with svgo and combine into a sprite for fewer requests.
- Respect license requirements in documentation/attribution files.
Recommended starter combos
- Web app: Heroicons + Font Awesome (for broad coverage)
- Mobile app: Material Icons or Ionicons
- Developer tools: Octicons + Tabler Icons
