Questions about finding Statsig
- How does PageSourceSearch know a website uses Statsig?
- By the source itself: The CDN script tag loads the statsig-js package or the newer @statsig/js-client bundle; the pattern matches both. PageSourceSearch stores the raw HTML and first-party JavaScript of each crawled site and matches the keyword byte for byte, so every listed site's stored source contains it.
- Is this a complete list of websites using Statsig?
- No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of 9 websites that do; the count is the index's estimate at the time the list was computed. Run the keyword as a search to page through all of them, or add a kind or date filter.
- How do I find websites that use Statsig together with another technology?
- Search for both keywords at once: several terms separated by spaces must all be found on the same site, or with the Same page toggle in the same page. For example statsig(-js|/js-client) with wp-content/plugins/ lists the WordPress sites that use Statsig.
