When building bookmark managers, link grids, speed-dial pages, dashboard link sections, or any UI that shows a collection of website links, you need icons for each site. Options: (1) Manually download and host icons — tedious, doesn't scale. (2) Use a big icon library like FontAwesome — doesn't have website-specific logos. (3) Use each site's /favicon.ico — unreliable, CORS blocked, inconsistent sizes, some sites use .png or .svg. (4) Use a favicon proxy service — the right answer. Without icons, link grids look bland and are hard to scan visually. Users rely heavily on favicon recognition for quick navigation.
