Jekyll is a static site generator built in Ruby, widely adopted by developers, technical bloggers, and open-source project maintainers who prioritize simplicity, version-controlled content, and fast-loading pages without the overhead of a database or CMS. AIWebsiteDetector.com identifies Jekyll-powered sites through meta tag analysis, with our detection engine relying on 1 distinct meta tag pattern that Jekyll embeds into rendered HTML by default — a lightweight but reliable fingerprint given how consistently Jekyll's templating system outputs structured metadata. Because Jekyll generates purely static output, it leaves no server-side execution traces or dynamic request headers, making the meta tag signal one of the more definitive indicators available for this builder. Jekyll is notably the engine behind GitHub Pages, meaning a significant portion of detected sites are hosted free of charge on GitHub's infrastructure — a characteristic that makes Jekyll simultaneously one of the most widely deployed and cost-free static generators on the web.
