Top Open Source Websites

Site Stats Database currently tracks 988 open source websites. We detect this by analyzing each site's homepage, response headers, and DNS, then enrich every record with traffic and authority data.

By number of sites, Open Source is #429 of 3,112 topics & industries that Site Stats Database tracks.

The most common topics among them are Software, Linux, and Community, and they are most common in United States and Germany. The breakdowns above show the full split, based on the 988 we track.

They tend to have stronger authority than the typical website: the median Open Source site has an Ahrefs Domain Rating of 70, higher than the 28 median across all sites Site Stats Database tracks.

Traffic estimates, organic keywords, and authority come from DataForSEO; Domain Rating comes from Ahrefs' public endpoint; and the topic, market, and tech detections come from Site Stats Database's own crawler, which inspects each site's HTML, headers, DNS, and TLS certificate.

At least monthly. Traffic and rankings refresh every month, and detections refresh as sites are re-crawled, so this page always reflects the current 988 open source websites.
