Top core-js Websites in English

core-js is the most widely used JavaScript standard-library polyfill set.

Site Stats Database tracks 240,069 websites that are both core-js and English, each enriched with traffic, authority, and the full detected tech stack.

They tend to have lower authority than the typical website: their median Ahrefs Domain Rating is 22, lower than the 28 median across all sites Site Stats Database tracks.

Traffic estimates, keywords, and authority come from DataForSEO; Domain Rating comes from Ahrefs' public endpoint; and the topic, market, and technology detections come from Site Stats Database's own crawler.
