HTTP Archive's annual
state of the web report
Our mission is to combine the raw stats and trends of the HTTP Archive with the expertise of the web community. The Web Almanac is a comprehensive report on the state of the web, backed by real data and trusted web experts. It is comprised of 22 chapters spanning aspects of page content, user experience, publishing, and distribution.Start exploring
This chapter reviews the current state of HTTP/2 and gQUIC deployment, to establish how well some of the newer features of the protocol, such as prioritization and server push, have been adopted. We then look at the motivations for HTTP/3, describe the major differences between the protocol versions and discuss the potential challenges in upgrading to a UDP-based transport protocol with QUIC.
The Web Almanac has been made possible by the hard work of the web community. 124 people have volunteered countless hours in the planning, research, writing and production phases.See the contributors
Unless otherwise noted, the metrics in all of the 22 chapters of the Web Almanac are sourced from the HTTP Archive dataset. HTTP Archive is a community-run project that has been tracking how the web is built since 2010. Using WebPageTest and Lighthouse under the hood, metadata about over 7.5 million websites are tested monthly and included in a public BigQuery database for analysis. The August 2020 dataset was used as the basis for the Web Almanac's metrics. For more information, see the Methodology page.Learn about our Methodology
