MaxCDN was one of the most popular WordPress CDN solutions — acquired by StackPath in 2016 and discontinued in 2023. As a CDN delivery platform it had no WCAG accessibility audit, no Core Web Vitals scoring, and no post-deployment front-end quality monitoring. PageGuard audits any website externally — free, no CDN access needed, results in 30 seconds.
ADA Title II Deadline: April 24, 2026
WordPress sites, small businesses, and agency-built websites that used MaxCDN for speed still face ADA Title III requirements for commercial websites and ADA Title II requirements for government and educational sites. MaxCDN (now defunct) delivered cached HTML pages at the edge — but whether those pages implemented correct alt text, keyboard navigation, ARIA roles, or color contrast was determined entirely by the origin HTML content. An accessibility regression cached and served at CDN edge PoPs is immediately delivered to all users with no CDN-level alert. PageGuard monitors any website for WCAG compliance regardless of what CDN or hosting delivers it.
PageGuard vs MaxCDN — WordPress CDN delivery infrastructure vs deployed website quality monitoring
| Feature | PageGuard | MaxCDN |
|---|---|---|
| What is it? | External website health monitor — scans any deployed URL for performance, accessibility, SEO, and best practices | MaxCDN was a popular content delivery network founded in 2009 and widely used by WordPress sites via W3 Total Cache and WP Super Cache plugins; MaxCDN was acquired by StackPath in 2016 and eventually rebranded under the StackPath CDN brand, which itself shut down in 2023 after StackPath sold its CDN infrastructure assets; MaxCDN's legacy lives on as one of the most widely-referenced CDN brands in the WordPress hosting ecosystem; as a CDN infrastructure service MaxCDN/StackPath focused entirely on accelerating content delivery through its global PoP network and had no capability to audit the HTML content it delivered for WCAG accessibility compliance, Core Web Vitals quality, or technical SEO correctness |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | MaxCDN no longer exists as a product — it was discontinued after StackPath shut down its CDN business in 2023; historically MaxCDN offered plans starting around $9/month for a fixed bandwidth allotment with no accessibility audit, no Core Web Vitals measurement, and no technical SEO scoring at any tier; current alternatives in the MaxCDN space include BunnyCDN, Cloudflare CDN, and KeyCDN, none of which provide front-end quality monitoring |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — MaxCDN was a CDN delivery infrastructure; it had no built-in WCAG compliance checking, accessibility scoring, or ADA compliance monitoring for the web pages it delivered; MaxCDN intercepted HTTP requests at its edge PoPs, applied caching rules, and delivered cached responses to end users — it did not parse, analyze, or validate the HTML content of those responses for missing alt text (WCAG 1.1.1), insufficient color contrast (WCAG 1.4.3), ARIA landmark structure (WCAG 1.3.1), keyboard navigability (WCAG 2.1.1), or any other WCAG 2.1 success criterion; MaxCDN could deliver accessible or inaccessible web pages with equal efficiency — accessibility quality was determined entirely by the origin server's HTML, not by the CDN delivery layer |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — MaxCDN provided no SEO audit of the web pages it delivered; MaxCDN could be configured to modify HTTP response headers (Cache-Control, Vary, X-CDN-Geo), enforce HTTPS redirects, and apply URL rewriting at the edge — but these were infrastructure-level delivery configurations, not content-level SEO audits; MaxCDN did not analyze the meta title, meta description, heading hierarchy, canonical URL tag, structured data markup, or internal link quality of the HTML pages delivered through its CDN; MaxCDN analytics showed traffic metrics, cache hit rates, and bandwidth consumption — not whether the delivered HTML had a missing title tag or duplicate H1 elements that could harm SEO |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — MaxCDN did not directly measure browser-side Core Web Vitals (LCP, CLS, FCP, INP) for pages it delivered; MaxCDN contributed to server-side performance through its global PoP network, edge caching, and low-latency routing — but these CDN-side improvements did not measure the actual browser-experienced LCP, CLS, or FCP of the rendered page; Core Web Vitals are browser-side metrics that depend on rendering, layout stability, and interactivity — factors beyond the CDN delivery layer's scope; the MaxCDN CDN dashboard showed origin response time, cache hit ratio, and bandwidth consumption — not Core Web Vitals scores |
| Global CDN delivery | No — PageGuard is an external monitoring tool, not a CDN or content delivery infrastructure | ✓ Yes (historically) — this was the core value proposition of MaxCDN: a global CDN network optimized for static asset delivery with particular strength in WordPress plugin integrations (W3 Total Cache, WP Super Cache, Gravity Forms CDN); MaxCDN operated PoPs across North America, Europe, and Asia-Pacific; the CDN supported HTTP/2, custom CNAMEs, full HTTP/HTTPS support, and origin pull caching; WordPress was the dominant use case, with MaxCDN becoming the most recommended CDN in WordPress speed optimization guides; MaxCDN is no longer available — as of 2023 StackPath shut down its CDN business |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — MaxCDN did not perform automated front-end quality monitoring of WCAG compliance, Core Web Vitals, or SEO quality for pages it delivered; MaxCDN's analytics and alerting focused on CDN operational health (cache hit ratio, origin error rates, bandwidth consumption) — not the HTML content quality, accessibility compliance, or SEO correctness of delivered pages; an accessibility regression introduced by a WordPress developer and immediately cached and served at MaxCDN's global edge would be invisible to MaxCDN's monitoring systems; MaxCDN is no longer available in any form |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — MaxCDN provided no AI-generated health report or plain-English explanation of front-end accessibility, SEO, or Core Web Vitals issues for pages it delivered; MaxCDN's reporting covered CDN performance metrics such as bytes transferred, cache hit ratio, and HTTP error rates — not content-level quality issues in the HTML being served to browsers; MaxCDN no longer exists as a product |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — MaxCDN did not audit or alert on WCAG compliance for pages it delivered; WordPress sites, small business websites, and agency-built sites that used MaxCDN still faced ADA Title III requirements for commercial websites — but the CDN layer played no role in detecting or preventing accessibility violations; MaxCDN delivered cached HTML pages to users but whether those pages implemented correct alt text, keyboard navigation, ARIA roles, sufficient color contrast, or proper focus management was determined entirely by the WordPress theme and plugins, not by the CDN delivery layer; an accessibility regression cached and served at MaxCDN's global PoPs was immediately delivered at scale with no MaxCDN alert or detection |
| Works on any deployed platform | ✓ Yes — scans any URL on any hosting or platform | MaxCDN delivered content for its contracted customers on its CDN network; it did not scan or monitor the front-end quality of web pages served by other CDNs or hosting platforms; PageGuard audits any URL regardless of whether it is served through a CDN, shared hosting, VPS, or cloud infrastructure |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — MaxCDN provided no built-in tool to generate a shareable external front-end health report for websites it delivered; MaxCDN's portal showed CDN performance analytics but these were internal operational dashboards, not client-shareable accessibility or SEO quality reports; MaxCDN is no longer available |
| Instant on-demand scan | ✓ Yes — results in 30 seconds, no code changes needed | No — MaxCDN had no on-demand front-end health scan of websites it delivered; auditing a MaxCDN-delivered website for WCAG accessibility, Core Web Vitals, or SEO quality required running third-party tools against the public URL; MaxCDN is no longer available |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | MaxCDN could serve multiple sites under an account with per-zone configuration and reporting; there was no multi-website front-end health dashboard showing WCAG compliance, SEO quality, or Core Web Vitals for sites delivered through MaxCDN's CDN; MaxCDN is no longer available |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Front-end health monitoring not available — MaxCDN was a CDN service priced by bandwidth starting around $9/month for 1 TB; it is no longer available as StackPath shut down its CDN business in 2023; no WCAG, Core Web Vitals, or SEO monitoring was ever offered at any tier |
Get a full WCAG accessibility, Core Web Vitals, and SEO report in 30 seconds — free, no CDN account access required.
Yes — PageGuard scans any public URL regardless of the CDN infrastructure delivering it. If you previously used MaxCDN and have migrated to a different CDN or hosting provider after its 2023 discontinuation, PageGuard can audit your current site for WCAG 2.1 AA accessibility, Core Web Vitals performance, technical SEO quality, and best practices in about 30 seconds. No CDN account access or configuration changes required.
No — MaxCDN was a CDN delivery infrastructure and had no built-in WCAG compliance checking, accessibility scoring, or ADA compliance monitoring for the web pages it delivered. MaxCDN intercepted HTTP requests at its edge PoPs and delivered cached responses — it did not parse or validate the HTML content for missing alt text, ARIA landmark structure, keyboard navigability, or color contrast. MaxCDN is no longer available (discontinued after StackPath shut down its CDN business in 2023). Detecting WCAG violations on any website requires an external audit tool like PageGuard.
MaxCDN was discontinued after StackPath shut down its CDN business in 2023. Common MaxCDN replacements for WordPress CDN include Cloudflare (free tier available), BunnyCDN (pay-per-use, very affordable), and KeyCDN. Whichever CDN you use for WordPress performance, you still need a separate tool like PageGuard to monitor your site for WCAG accessibility compliance, Core Web Vitals scores, and technical SEO quality — functions no CDN provides.
No — they serve completely different purposes. MaxCDN was a global CDN that accelerated static asset delivery and reduced server load through edge caching, particularly popular with WordPress sites. PageGuard is an external quality monitoring tool that audits deployed web pages for WCAG accessibility compliance, Core Web Vitals performance, and technical SEO quality. WordPress site owners who used MaxCDN for speed should use PageGuard to also verify that their pages meet WCAG requirements — accessibility quality that no CDN can enforce on the origin HTML content it serves.
