Who's Visiting the Web? A User-Agent Analysis of 1.3 Million Requests — and Why Only a Quarter Are Human
We classified 1.32 million HTTP requests across 14,828 unique user agents. Human browsers are down to 24.8% of traffic. The category mix has inverted since first publication: HTTP libraries (curl, Go, Python) and crawlers now tie for the lead at roughly a third each, while desktop browsers fell to 21.9% and AI crawlers — though still growing in volume — saw their share roughly halve to 7.3%. Full breakdown by category, browser, OS, and crawler operator, triangulated against Imperva and Cloudflare.
