Platform Overviews

Eleventy

Eleventy (also styled as 11ty) is a flexible, JavaScript-based static site generator favored by developers, technical bloggers, and performance-focused teams who want full control over their output without the overhead of a heavyweight framework. Unlike opinionated generators, Eleventy imposes minimal structure, making it a popular choice for personal sites, documentation portals, and design systems where clean, fast HTML is the priority. AIWebsiteDetector.com identifies Eleventy-powered sites through meta tag pattern analysis — specifically, the generator meta tag embedded in the document head, which Eleventy injects by default and serves as the primary fingerprint our detection engine relies on. With 1 confirmed meta tag pattern in our detection database, the engine achieves reliable identification even when developers have customized themes or stripped other build artifacts. Eleventy sites are typically self-hosted or deployed via JAMstack platforms such as Netlify, Vercel, or GitHub Pages, and because the framework produces purely static output with no mandatory client-side runtime, the generator meta tag often remains the sole detectable signal — making it a uniquely minimalist target for automated detection compared to more footprint-heavy builders.

Astro

Astro is a modern static site generator and web framework designed for content-focused websites, widely adopted by developers building blogs, documentation platforms, marketing sites, and portfolios who prioritize performance through minimal JavaScript delivery. AIWebsiteDetector.com identifies Astro-powered sites using a combination of 2 distinct script patterns, 3 HTML patterns, and 1 HTTP header signal — a precise fingerprint that reflects how Astro renders its component island architecture into the DOM. The HTML patterns typically surface in the markup structure and custom attributes Astro injects during its build process, while the script patterns correspond to Astro's client-side hydration modules that accompany interactive components on the page. The HTTP header signal further corroborates detection, often appearing in server or CDN response metadata associated with Astro's deployment targets such as Netlify, Vercel, and Cloudflare Pages. Astro is open-source and free to use, with hosting costs determined entirely by the chosen deployment platform, making it a common choice across a wide spectrum of project scales — from personal sites to enterprise documentation. This multi-signal detection approach gives AIWebsiteDetector.com high confidence when classifying Astro sites, as the combination of build-output HTML markers and runtime script patterns is difficult to mask without fundamentally altering Astro's default output behavior.

Key Differences

  • Both Eleventy and Astro are classified as AI Coding Tool tools, making them the most direct competitors in this comparison.
  • Eleventy scores higher on AI involvement (65/100 vs 65/100 for Astro), meaning it relies more heavily on AI for site generation and content creation.
  • Our detection engine identifies Eleventy using 1 fingerprint pattern and Astro using 6 patterns — more signals generally means more reliable detection.

Which Should You Choose?

Choose Eleventy if…

  • You prefer a ai coding tool solution
  • You want more manual control over the final output
  • Eleventy's detection fingerprint of 1 signals means your site is reliably identifiable

Choose Astro if…
