overLIB on new websites

1. overLIB appeared on about 33 new sites in the last 30 days.^[1]
2. Nine in ten new overLIB sites also use jQuery.

The line is the 7-day average share of new sites that use overLIB, day by day for the last 90 days and weekly before that (left of the dashed line). It starts at our first detection. The shaded areas were measured against a different set of sites, so the line can step there without overLIB itself changing.^[2][3]

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

1 of the 93 sites using overLIB are product launches we list individually. The other 92 are sites we found crawling the wider web: they count towards the figures above, but we do not publish them one by one. They are included in the StackScope API and in Stackdar alerts.

1. These figures cover websites that went live since April 2026, not the web as a whole.
2. Grey: before 8 July 2026, we only tracked launches from launch platforms. From that date we crawl the wider web as well, so the share is measured against a much larger set of sites. For one continuous measure, view launch platforms only.
3. Amber: 8 July to 10 September 2026, before we improved our infrastructure to index new sites much sooner, often on the day they go live. Sites found that early often haven't finished setting up, so anything usually added after launch reads lower from 10 September. We record each site as it was when we found it.
4. 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.
5. Some products people expect to see here are filed under a related category: UI Library.
