fav.farm (via) Neat little site by Wes Bos: it serves SVG (or PNG for Safari) favicons of every Emoji, which can be added to any site like this:

<link rel="icon" href="https://fav.farm/🔥" />

The source code is on GitHub. It runs on Deno and Deno Deploy, and recently added per-Emoji hit counters powered by the Deno KV store, implemented in db.ts using this pattern:

export function incrementCount(emoji: string) {
  const VIEW_KEY = [`favicon`, `${emoji}`];
  return db.atomic().sum(
    VIEW_KEY, 1n
  ).commit(); // Increment KV by 1
}
