Share is of the 13,986 sites using a data api tool; a site can use more than one. A flag means nearly all of a tool's sites are in that country. Arrows compare each tool's rank among sites launched in September with August. The line is its share of new sites over 90 days. Showing the top 15 of 1,508.

Watches, exports and the API give you every data api tool and the sites using each, from £15 a month.

Other kinds of tool most often found on the same sites, leaving out the plumbing every site has (DNS, CDN, hosting).
