Top Open Source Websites Using Google Tag Manager

Google Tag Manager is a tag-management system for deploying tracking and marketing tags without editing site code. Marketers use it to add analytics, ad pixels, and scripts through a web interface. It frequently appears alongside Google Analytics and ad tools.

Site Stats Database tracks 188 websites that are both Google Tag Manager and Open Source, each enriched with traffic, authority, and the full detected tech stack.

They tend to have stronger authority than the typical website: their median Ahrefs Domain Rating is 73, higher 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.
