Notes
- These figures cover websites that went live since April 2026, not the web as a whole.
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 HTML Tidy when we detect HTML Tidy 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 ยท How we find new sites
