Recently launched products built on Prototype
6 of the 1,038 sites using Prototype are product launches we list individually. The other 1,032 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 1,038 sites using Prototype, from £15 a month.
Notes
- These figures cover websites that went live since April 2026, not the web as a whole.
- 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. Too few sites state their country plainly for the usual count, so this one also counts single signals: a country domain ending, a phone number (for North America, its area code), a location the site declares in its own page metadata, or a country-specific vendor stack and the page language where they agree and nothing contradicts them. Read these as likely rather than certain.
- Some products people expect to see here are filed under a related category: Meta Framework, Backend Framework.
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 Prototype when we detect Prototype 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
