Companies Using Jekyll

Our live crawl finds Jekyll on 7,537 domains, resolving to 3,106 identifiable organisations. Named users include Ticketmaster, GitHub, the Apache Software Foundation, Bugcrowd, Cisco Talos, OpenSearch, Expensify and Discourse. Software development and IT services account for 44.87% of the matched base, and most detections sit on a documentation, careers or project subdomain rather than a company's main site.

We detect Jekyll on 7,537 active domains as of our August 2026 rollup, of which 3,106 resolve to a company record. Treat that as a floor rather than a total: Jekyll is identified mainly by the generator meta tag it writes into each page, and themes can remove that line without affecting the site, so any Jekyll build that strips it is invisible to us.

Jekyll holds 0.69% of Static Site Generators and ranks 5th, behind Next.js at 731,970 domains, Astro at 287,180, Gatsby at 29,767 and Hugo at 28,690. The comparison is not like-for-like, because the four generators ahead of it leave runtime signals that a build cannot suppress and Jekyll leaves a removable comment.

Astro is the alternative our data actually supports. 49 domains dropped Jekyll and kept Astro in the window we observed, and none moved the other way. Hugo is the closest like-for-like swap, since both are single-binary or single-gem generators with no JavaScript runtime, and Next.js is the option people choose when the site stops being only documentation.

The United States leads with 802 matched companies (33.56%), followed by the United Kingdom at 271 (11.34%), Germany at 191 (7.99%), India at 139 (5.82%) and France at 117 (4.90%).

76.52% of matched Jekyll companies employ 1 to 10 people and 16.07% employ 11 to 50. Only 88 of the 3,106 matched organisations employ more than 200. Large organisations do appear, but usually on one subdomain rather than across the estate.

51.85% of matched companies were founded in the 2010s and 26.97% in the 2020s, with 14.61% dating from the 2000s. Jekyll's own release in 2008 sits just before the decade that dominates its base.

A software or IT services company of 1 to 10 people, founded in the 2010s, based in the US, UK or Germany, publishing documentation or a project site rather than a marketing site.

58.28% of the domains where we detect Jekyll also run GitHub Pages, which builds Jekyll natively without any configuration. The relationship shows up twice in our data, because GitHub Pages serves through Fastly and Fastly appears on 57.17% of the same base. The other 3,321 domains build Jekyll themselves and serve it elsewhere, mostly behind Cloudflare (37.01%) or Netlify (21.38%).

Because the signal is optional. Jekyll writes a generator meta tag into each page and that is what we match on; deleting the line is a one-word theme edit that changes nothing else. Every Jekyll site whose theme removed it is a site we cannot see. The generators ranked above Jekyll do not have this property, so the category ranking compares a suppressible signal against unsuppressible ones.

In the window we observed, yes, and only in that direction. 49 domains dropped Jekyll while keeping Astro and none dropped Astro while keeping Jekyll. The corridor is small in absolute terms and we do not publish the Next.js or Hugo equivalents, because 85.71% and 73.33% of those pairs still run both technologies, which describes coexistence rather than movement.

Documentation and project sites, overwhelmingly. Software development, IT services and technology account for 54.47% of the matched base, and the detections resolve to hosts like developer.ticketmaster.com, archiveprogram.github.com, talosintelligence.com and opensearch.org. Google Analytics appears on only 48.09% of Jekyll domains, well below what a marketing site would show, which is consistent with the same reading.
