How this tool works

Browse the most central domains of the open web, ranked by Common Crawl's Harmonic Centrality (the spam-resistant signal Common Crawl uses to prioritise its crawl). Filter by TLD to see, say, the strongest .fr or .io domains.

Harmonic Centrality measures how "close" a domain is to all other domains in the web graph (reachable through few link hops); PageRank, shown alongside, measures authority from the quantity and quality of incoming links. Data is the latest Common Crawl release (top 12M domains), free and open, no API key, served instantly from a local copy.
