Any service that stores/indexes information linked to a domain could use this to increase the recognition factor for the customer when listing a set of domains.

A great example is 1Password, when you type in the url of an account, it fetches the favicon and displays it when listing your accounts, making is very easy to quickly scroll and recognize what you want.

Yet it feels like this is something you could just build a library for in your web app. I'm sure there are favicon pullers/cachers for every language out there. I know tt-rss has one for it's RSS job.

It seems like something silly to depend on an external service for.

My mind went to password managers too - something like tis would be great for KeePass/MacPass because its favicon grabber is hit or miss
