Majesticons
Majesticons is a free MIT-licensed icon library by Gerrit Halfmann (also the author of Pixelarticons). The set contains 1,045 icons drawn on a 24×24 grid in coordinated line and solid weights. Where Halfmann's other library Pixelarticons leans into deliberate retro pixel geometry, Majesticons is a more conventional, contemporary outline-and-fill family designed for clean web and product interfaces. Stroke weights are slightly heavier than Tabler's, which makes the icons read more confidently at small sizes inside table rows and buttons, while the rounded corners keep the overall feel approachable. Majesticons is a good middle-of-the-road default when you want something a bit more characterful than the most neutral icon sets but don't need the full nine-style sprawl of larger libraries like Huge Icons or Phosphor.
