Tabler Icons

Tabler Icons is the biggest open-source icon library you've probably overlooked. Over 6,000 MIT-licensed SVG icons on a consistent 24px grid, with first-class React, Vue, and Svelte packages. That's 4x more icons than Lucide and 20x more than Heroicons.

If you constantly hit icon gaps with smaller libraries, Tabler Icons eliminates the problem through sheer coverage. Every icon uses the same stroke width, so you can adjust thickness via CSS for different visual weights. Lucide is the trendier choice (it's shadcn's default) with better ecosystem momentum. Heroicons is more curated but tiny at 292 icons. React Icons aggregates everything but bloats your bundle.

The catch: quantity doesn't equal quality for every icon. With 6,000+ icons, consistency varies — some feel polished, others feel like they were added to hit a number. The library isn't the default anywhere notable, so you'll be importing a less-recognized dependency. And at this scale, the Figma plugin and search experience matter more than the icons themselves.
