HTTP Archive is a lab tool, meaning that it measures how individual web pages are built. Like CrUX, it's a public dataset, and it's actually based on the same websites in the CrUX corpus, so we have perfect parity when combining the two sources together. HTTP Archive is powered by WebPageTest, which integrates with other lab tools like Lighthouse and Wappalyzer to extract fine-grained data about the page. Lighthouse runs audits against the page to determine how well-optimized it is, for example if it takes advantage of web performance best practices. Wappalyzer is an open-source tool that detects the use of technologies like an entire CMS, a specific JavaScript library, and even what programming languages are probably used on the backend. These detections are what we use in the CWV Technology Report to segment the real-user experience data from CrUX.
The technologies you use to build your website can have an effect on your ability to deliver good user experiences. Good UX is key to performing well with Core Web Vitals (CWV), a topic which is probably top of mind for you, as it is for many other web developers now that these metrics play a role in Google Search ranking. While web developers have had tools like Search Console and PageSpeed Insights to get data on how their sites are performing, the web community has been lacking a tool that has operated at the macro level, giving us something more like WebSpeed Insights. By combining the powers of real-user experiences in the Chrome UX Report (CrUX) dataset with web technology detections in HTTP Archive, we can get a glimpse into how architectural decisions like choices of CMS platform or JavaScript framework play a role in sites' CWV performance. The merger of these datasets is a dashboard called the Core Web Vitals Technology Report.

The CrUX dataset on BigQuery is aggregated at the origin level. An origin is a way to identify an entire website. For example, https://httparchive.org is the origin for the HTTP Archive website and it's different from https://almanac.httparchive.org, which is a separate origin for the Web Almanac website.
