Share is of the 165,398 sites using an os tool; a site can use more than one. 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 10 of 14.

Watches, exports and the API give you every os 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).
