Tools that turn up far more often on Evercookie sites than on new sites in general, and how many times as common each one is there.
47 sites across the wider web use Evercookie
None of them is a product launch we list individually, so there is nothing to show here. They still count towards the figures above. How we find new sites
Watches, exports and the API give you all 47 sites using Evercookie, from £15 a month.
Notes
- These figures cover websites that went live since April 2026, not the web as a whole.
- Some products people expect to see here are filed under a related category: UI Library.
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 Evercookie when we detect Evercookie 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
