Notes

  1. These figures cover websites that went live since April 2026, not the web as a whole.
  2. 15 October 2026: Detection made stricter: a site now counts only when this technology loads on the page. Launches crawled before this date may overcount. The dashed line on the chart marks the day.
  3. Country comes from what each site says about itself, such as a company registration, legal terms or a phone number, not just its domain ending. We count a country only where it is stated plainly enough to be sure: a governing-law clause or company registration number on a legal page, a phone country code, or a country domain ending. Sites that publish none are not counted at all.
  4. Green hosting is the share whose web host The Green Web Foundation lists as running on green energy, among sites checked since 1 April 2026, against the same share for every new site we checked over that time. Data from The Green Web Foundation.
  5. Some products people expect to see here are filed under a related category: CDN.

How this page is made

FirstSited looks at each new website near the day it goes live and records what it was built with. We do not go back later, so these figures describe what sites launch with, not what they run today. A site counts towards Google Hosted Libraries when we detect Google Hosted Libraries on it at that look.

Every share on this page is a proportion of the new sites we were tracking at the time. Sites we found across the wider web count towards the figures, but only product launches are listed by name. How we detect technologies · How we find new sites
