Recently launched products built on Marker.io

10 of the 124 sites using Marker.io are product launches we list individually. The other 114 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 124 sites using Marker.io, from £15 a month.

Notes

  1. These figures cover websites that went live since April 2026, not the web as a whole.
  2. 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.

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 Marker.io when we detect Marker.io 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
