Calculate Market Size Founder Fit Assessment Back to All Ideas

● The Problem

Developers building link previews, bookmarking tools, or dashboards need favicons. Google S2 API is unreliable and most sites serve favicons inconsistently.

● The Solution

A simple REST API that fetches, caches, and returns favicons for any domain. Falls back through multiple sources (HTML link tags, manifest.json, common paths) to always return an icon.
