Tools that turn up far more often on OSM Buildings sites than on new sites in general, and how many times as common each one is there.

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 284 sites using OSM Buildings, from £15 a month.

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. 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.
