Seven sets, honestly credited.

LucideISC

1,611 icons in the package · 106 compared here · 24 × 24 · 2px stroke

The community fork of Feather that kept growing — consistent 2px strokes on a 24px grid, rounded joins, and a deliberately calm temperament. Since v1.0 it contains no brand logos at all.

HeroiconsMIT

324 icons in the package · 106 compared here · 24 × 24 · 1.5px stroke

By the makers of Tailwind CSS. A lighter 1.5px stroke than most, with slightly literary, UI-first shapes — the default look of a large slice of the modern web.

Tabler IconsMIT

5,093 icons in the package · 106 compared here · 24 × 24 · 2px stroke

The biggest catalog of the seven by a wide margin — thousands of 2px-stroke icons with unusually deep coverage of niche objects, all drawn to one disciplined grid.

PhosphorMIT

1,512 icons in the package · 106 compared here · 256 × 256

Six weights of the same drawing, from thin to fill — the typographic approach applied to icons. We show the regular weight; the character is friendly and a touch rounder than its peers.

FeatherMIT

287 icons in the package · 106 compared here · 24 × 24 · 2px stroke

Cole Bemis's original minimalist set — under 300 icons, each pared to the fewest strokes that still read. The ancestor Lucide grew from; comparing the two side by side is half the fun.

Remix IconApache-2.0

3,229 icons in the package · 106 compared here · 24 × 24

A large neutral-tempered set drawn as filled outlines rather than strokes — crisp at small sizes and the closest of the seven to a classic “system icon” voice.

IconoirMIT

1,383 icons in the package · 106 compared here · 24 × 24 · 1.5px stroke

Luca Burgio's hand-drawn-feeling 1.5px strokes — slightly looser geometry than Lucide or Tabler, which gives interfaces built with it a more personal, sketched warmth.
