Pikaday on new websites

1. Pikaday appeared on about 330 new sites in the last 30 days.^[1]
2. Nine in ten new Pikaday sites also use jQuery.
3. It is unusually common on .fr domains: 34% of the domains running it, against 1.9% of domains across new sites.

The line is the 7-day average share of new sites that use Pikaday, 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 Pikaday itself changing.^[2][3]

All-time shares across the new sites we track: of all of them, and of the sites using any Javascript Library tool. Pikaday is typically used alongside jQuery rather than instead of it. Among September launches it ranked #156 in Javascript Library, up from #187 in August. All 1543 in Javascript Library

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

10 of the 793 sites using Pikaday are product launches we list individually. The other 783 are sites we found crawling the wider web: they count towards the figures above, but we do not publish them one by one.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. 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.
5. Some products people expect to see here are filed under a related category: UI Library.
