Eleventy is a flexible JavaScript static site generator with 17K+ GitHub stars, support for 11 templating languages, and zero client-side JavaScript by default — but as a build tool it has no built-in WCAG accessibility audit, no Core Web Vitals scoring, and no post-deployment health monitoring. PageGuard audits the live deployed URL of any Eleventy site externally — free, no Node.js environment needed, results in 30 seconds.
ADA Title II Deadline: April 24, 2026
State and local government websites must meet WCAG 2.1 AA by April 24, 2026. Eleventy is popular among government agencies, nonprofits, and universities that value its simplicity, speed, and zero-JS output. However, Eleventy’s multi-language templating system produces front-end HTML whose accessibility is entirely determined by how developers author Nunjucks includes, Liquid templates, and WebC components — alt text in image shortcodes, ARIA labels in navigation macros, keyboard operability of any JavaScript widgets, and semantic heading structure all require runtime verification that Eleventy does not provide. PageGuard audits your live Eleventy site after each build and deployment, alerting you to accessibility regressions before the April 24 deadline.
| Feature | PageGuard | Eleventy (11ty) |
|---|---|---|
| What is it? | External website health monitor — scans any URL for performance, accessibility, SEO, and best practices | JavaScript static site generator (SSG) known for its simplicity and flexibility — zero client-side JavaScript by default, supports 11 templating languages (Nunjucks, Liquid, Markdown, WebC, etc.), works with any CSS framework or bundler; 17K+ GitHub stars; popular with developers who want full control over output |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | Free and open source (MIT license); deploy output to any CDN or static host (Netlify, Vercel, GitHub Pages, Cloudflare Pages) — many offer free tiers |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — Eleventy generates static HTML but has no built-in WCAG or ADA accessibility auditing of the deployed output; accessibility depends entirely on how templates and shortcodes are authored |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — Eleventy has no built-in SEO auditing; developers add meta/OG tags manually in templates or via community plugins, but there is no audit of the deployed page's SEO quality |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — Eleventy produces zero client-side JavaScript by default which helps performance, but image optimization, font loading, and third-party scripts still impact LCP, CLS, and FCP and are not measured by Eleventy itself |
| Static site generation | No — PageGuard is a monitoring tool, not a static site generator | ✓ Yes — Eleventy transforms templates written in 11 different languages into optimized static HTML; zero client-side JS by default, no framework lock-in, outputs lean HTML that is fast to serve |
| Multi-template language support | No — PageGuard is a standalone monitoring service | ✓ Yes — Eleventy supports HTML, Markdown, Liquid, Nunjucks, Handlebars, Mustache, EJS, Haml, Pug, JavaScript, and WebC templating languages in a single project |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — Eleventy is a build tool; it has no post-deployment health monitoring, accessibility regression alerts, or performance tracking for the live production site |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — no AI health report for the deployed production site |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — Eleventy does not audit or alert on WCAG compliance in the deployed static output; compliance depends on template code, shortcodes, and any third-party JavaScript or widgets added to the site |
| Works on any platform | ✓ Yes — scans any URL on any front-end or platform | No — Eleventy builds your own site only; it does not audit sites built on other platforms or by other generators |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — no built-in tool to generate a shareable external health report for a deployed Eleventy site |
| Instant on-demand scan | ✓ Yes — results in 30 seconds, no code changes needed | No — no on-demand health scan; external auditing of deployed Eleventy sites requires separate tools like Lighthouse or axe |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | Eleventy builds individual sites; there is no health monitoring dashboard showing accessibility, SEO, and performance scores across multiple Eleventy sites |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Health monitoring not available — Eleventy is a static site generator, not a website health monitoring tool |
Get the WCAG accessibility score and Core Web Vitals that Eleventy doesn’t provide for your deployed static site. Results in 30 seconds. No repository access, npm installation, or Eleventy plugin required.
Results in ~30 seconds. 4 scores: Performance, Accessibility, SEO, Best Practices.
Yes — PageGuard scans the live deployed URL of any Eleventy (11ty) website hosted on Netlify, Vercel, Cloudflare Pages, GitHub Pages, or any CDN. Enter the public URL and receive a full health report in ~30 seconds covering Core Web Vitals, WCAG 2.1 AA accessibility, technical SEO, and best practices. No Node.js environment, repository access, or Eleventy plugin installation is required.
No — Eleventy generates static HTML but does not audit WCAG compliance of the deployed output. Despite zero client-side JS by default, accessibility still depends on how templates, Nunjucks/Liquid includes, and shortcodes are authored. Alt text on images, ARIA attributes in navigation, color contrast in CSS, keyboard operability of any interactive widgets, and semantic heading structure are the developer’s responsibility. PageGuard audits your live Eleventy site and provides a WCAG 2.1 AA score with specific issues to fix.
Eleventy handles the build layer: converting templates in 11 languages into optimized static HTML with zero client-side JS and no framework lock-in. PageGuard audits the production layer: (1) WCAG/ADA accessibility of the rendered static HTML Eleventy produces, (2) Core Web Vitals performance (LCP, CLS, FCP) including image optimization and third-party scripts on the deployed site, (3) technical SEO quality including meta tags added via templates, and (4) automated monitoring with email alerts when template changes introduce regressions — from $9/mo.
No — they serve completely different purposes. Eleventy is a flexible JavaScript static site generator that outputs clean, lean HTML from multiple templating languages with zero client-side JS and no framework lock-in. PageGuard is an external quality monitoring tool for your deployed front-end. Developers and agencies building Eleventy sites should use both: Eleventy to build and generate static HTML, PageGuard to verify the production site meets accessibility compliance and performance standards after every deployment.
