Web Almanac is an annual, crowd-sourced survey and report analyzing the state of the modern World Wide Web through empirical measurement and thematic chapters. It synthesizes large-scale datasets about HTTP Archive, Google, Cloudflare, Mozilla, Microsoft, W3C, Akamai, Fastly, Apple, Amazon (company), GitHub and other institutions to present trends in web performance, accessibility, security, and standards. Contributors include researchers from WHATWG, IETF, OpenJS Foundation, Linux Foundation, WebKit, Blink (browser engine), Chromium, Opera (web browser), and academic groups across Stanford University, Massachusetts Institute of Technology, University of Oxford, University of Cambridge, ETH Zurich.

Overview

The report aggregates metrics from the HTTP Archive corpus, browser telemetry from Google Chrome, Mozilla Firefox, and CDN logs from Cloudflare, Akamai, and Fastly to quantify adoption of technologies such as HTML5, CSS, JavaScript, WebAssembly, Service Worker, Progressive Web App, AMP (Accelerated Mobile Pages), TLS, HTTP/2, HTTP/3, QUIC, and Content Security Policy. Chapters examine accessibility relative to WCAG, security practices tied to Let’s Encrypt, privacy features in GDPR, CCPA, and e-commerce patterns involving Shopify, Magento, WooCommerce, and Amazon (company). The Almanac frames findings with references to standards bodies like W3C and IETF, industry platforms like WordPress, Drupal, and Squarespace, and browser vendors such as Google, Apple, Microsoft, Mozilla.

History and Development

Conceived as an extension of the HTTP Archive initiative, the Almanac originated in collaboration between HTTP Archive, Google, and Cloudflare following earlier measurement projects by Akamai and academic teams at Carnegie Mellon University and University College London. Early editions were influenced by measurement reports from State of the Web studies and benchmarking efforts like the WebPagetest project and analyses published by W3Techs and Netcraft. Over successive editions, editors partnered with contributors from ACM SIGCOMM, IEEE, USENIX, and open-source communities including Node.js Foundation and OpenJS Foundation to expand topical coverage and methodological rigor.

Methodology and Data Sources

Methodology centers on large-scale crawls using the HTTP Archive dataset, which collects page-level traces via tools such as WebPageTest, Puppeteer, and Selenium (software), supplemented by CDN edge telemetry from Cloudflare and browser telemetry from Google Chrome and Mozilla Firefox. Datasets are cross-referenced with domain registries like ICANN and hosting information from Amazon Web Services, Google Cloud Platform, Microsoft Azure, and registrar data from GoDaddy. Statistical techniques draw on methods used in publications by ACM, IEEE, and Nature (journal), with reproducible analysis in notebooks using Jupyter, Pandas, NumPy, and visualization via D3.js, Tableau, and Matplotlib.

Key Findings by Topic

Chapters report on performance metrics such as Time to First Byte, Largest Contentful Paint, and lifecycle events impacted by HTTP/2, HTTP/3, and QUIC, noting adoption trends among sites hosted on Amazon Web Services, Cloudflare, and Fastly. Accessibility chapters reference WCAG conformance patterns and common issues seen on sites built with WordPress, Joomla, Drupal, and bespoke frameworks maintained by teams at Facebook, Twitter, LinkedIn, and Spotify. Security findings highlight uptake of TLS via Let’s Encrypt certificates, use of Content Security Policy, and deployment of Subresource Integrity across e-commerce platforms like Shopify and Magento. JavaScript ecosystem coverage examines frameworks and libraries such as React (JavaScript library), Angular (application platform), Vue.js, jQuery, Ember.js, and the emergence of WebAssembly in high-performance workloads exemplified by projects at AutoDesk, Figma, and Unity (game engine). Mobile web and PWA adoption trends reference app distribution models employed by Google Play, Apple App Store, and cross-platform tools from Ionic (framework) and Cordova (software). Privacy-related chapters evaluate effects of GDPR, CCPA, and browser features like Intelligent Tracking Prevention in Safari (web browser) and tracking mitigations in Firefox.

Impact and Reception

The Almanac has been cited by standards bodies including W3C and IETF in working group discussions and referenced by industry reports from Gartner, Forrester Research, McKinsey & Company, and technology blogs run by Mozilla and Google Developers. Academic papers published in venues such as ACM SIGCOMM, IEEE Internet Computing, and USENIX Symposium on Networked Systems Design and Implementation have used Almanac datasets for analyses of web trends. Advocacy organizations like Electronic Frontier Foundation and accessibility groups including W3C Web Accessibility Initiative and AbilityNet have leveraged findings in policy and outreach. Media coverage appeared in outlets such as The New York Times, The Guardian, Wired (magazine), TechCrunch, and The Verge.

Access and Publication Process

Annual editions and datasets are published alongside the HTTP Archive with open data releases, reproducible analysis notebooks, and chapter contributions coordinated through repositories on GitHub. Publication cycles typically involve editorial review by volunteer editors from Cloudflare, Google, Mozilla, Akamai, academic partners at Stanford University and MIT, and community reviewers from WHATWG and IETF. Licensing commonly uses Creative Commons terms to encourage reuse by educators, researchers at institutions like Harvard University and Princeton University, and practitioners at firms such as Mozilla Corporation and Google LLC.
