Methodology

Every figure on this page comes from a direct programmatic count of the icon files in each library's indexed release — not from marketing claims or upstream READMEs. The snapshot was generated on 2026-05-05 and the machine-readable source is published at /data/index.json.

Icon counts reflect distinct SVG glyphs in the version listed. Where a library ships multiple weights or styles of the same concept (for example Phosphor's six weights), each distinct exported file is counted once. License classifications follow each library's published LICENSE file at the indexed version. Solar Icons is classified as CC BY 4.0 (attribution requested); all other counts fall under MIT, Apache 2.0, ISC, or CC0.
