Recently launched products built on Pi
10 of the 14 sites using Pi are product launches we list individually. The other 4 are new business and personal sites: they count towards the figures above but are not listed here. A watch sends them to you.
Watches, exports and the API give you all 14 sites using Pi, from £15 a month.
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 Pi when we detect Pi 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
