HSTS on new websites

1. About 1 in 2 websites that went live in the last 30 days use HSTS (45.5%).^[1]
2. It is the most common security service on new sites, more than twice as common as the next, Cloudflare Bot Management.

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

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

668,624 of the 2,823,941 sites using HSTS are product launches we list individually. The other 2,155,317 are sites we found crawling the wider web: they count towards the figures above, but we do not publish them one by one.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.

The StackScope API serves all 2,823,941 sites using HSTS, filterable and exportable, from £15 a month.

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. Green hosting is the share whose web host The Green Web Foundation lists as running on green energy, among sites checked since 1 April 2026, against the same share for every new site we checked over that time. Data from The Green Web Foundation.
