Introduction to the HTTP Archive

Feb 26, 2026, 5:30 PM UTC (see full event)

The HTTP Archive is an open source project that tracks how the web is built and how it's evolved. The archive contains information on ~15 million websites, with monthly data for some sites as early as 2010! The data from the HTTP Archive is frequently used for research by the web community and scholars, and also used to produce the annual Web Almanac. During this session Paul will provide an overview of the HTTP Archive and demonstrate how to get started querying it.

Paul Calvano (he/him) is a Performance Architect at Etsy, where he helps optimize the performance of their marketplace. He has been helping websites optimize their performance since as early as 2000. He is also a co-maintainer of the HTTP Archive and a co-organizer of the NY Web Performance Meetup.
