favipulse
Favicons that say something: who, where, and what's happening.
Draw a deterministic generative favicon from any seed (with an optional self-drawing animation), show unread badges, a progress ring for builds and uploads, a pulse when something needs attention, and give dev, staging and prod their own unmistakable icon. Typed, ESM + CJS, SSR-safe. The maintained replacement for favico.js and tinycon.

// Generated icon + badge

const fav = favipulse({ seed: 'acme', env: 'auto' });
fav.badge(3);// Progress ring while uploading
fav.progress(0.42); // or 42
fav.progress(null); // done
fav.pulse(); // needs attention# Static sets per environment
npx favipulse generate --seed acme --out public/favicons// Vite
