Interesting service. I am building a bookmarking app that needs to load a lot of favicons.

There are libraries like this: https://github.com/zongyz/get-website-favicon, but I suppose your service is even easier to use.

The big feature I would be interested in is being able to load multiple favicons at the same time as a sprite sheet: loading favicons one-at-a-time is very slow and inefficient.

An example of a site that caches favicons as a sprite sheet is https://www.bkmks.com/

Whoa, I hadn't thought of a sprite sheet, but that's a great idea actually. It shouldn't be too hard to generate one of these. How many favicons in one sheet are you thinking?

I don't know... but a lot!

I have 1500+ bookmarks: https://instant.leftium.com/

And here's what my bkmks.com spritesheet looks like: https://i.imgur.com/dgoBEC4.png
