KeyCDN delivers website assets through 40+ global PoPs with HTTP/3, Brotli compression, and WebP image optimization — but as a pure performance CDN it has no WCAG accessibility audit of the pages it delivers, no Core Web Vitals scoring, and no post-deployment front-end quality monitoring. PageGuard audits any website using KeyCDN externally — free, no KeyCDN account access 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. Government agencies, nonprofits, and educational institutions using KeyCDN to deliver website assets for public-facing pages face this compliance deadline. KeyCDN's Image Processor can serve optimized WebP images, but cannot verify whether the surrounding HTML correctly implements alt text, ARIA attributes, or image dimensions that prevent CLS. An accessibility regression in HTML pages delivered through KeyCDN zones is served instantly to all users at full CDN speed — with no KeyCDN alert, detection, or monitoring. PageGuard checks all pages delivered through KeyCDN zones without requiring your KeyCDN API key or zone credentials.
| Feature | PageGuard | KeyCDN |
|---|---|---|
| What is it? | External website health monitor — scans any deployed URL for performance, accessibility, SEO, and best practices | KeyCDN is a Swiss performance-focused content delivery network founded in 2012 and headquartered in Zürich, Switzerland; KeyCDN operates 40+ globally distributed PoPs including locations in North America, Europe, Asia-Pacific, South America, and Africa; KeyCDN core products include Pull Zones (CDN delivery from your origin server), Push Zones (CDN storage for static files like images, CSS, JS, video), KeyCDN Image Processor (on-the-fly image optimization and resizing via URL parameters), and real-time analytics dashboard; KeyCDN supports HTTP/2 and HTTP/3, Brotli compression, Gzip, TLS 1.3, and automatic WebP image format conversion; KeyCDN is a pure performance CDN and does not analyze the accessibility compliance, SEO quality, or Core Web Vitals of the websites it delivers |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | No — KeyCDN does not offer a free tier; KeyCDN is usage-based with pricing starting at $0.04/GB for North America and Europe, $0.10/GB for Asia-Pacific and South America, $0.15/GB for India, and $0.25/GB for Africa; minimum annual commitment of approximately $49/year; KeyCDN also offers a 14-day trial with a $10 credit; however, KeyCDN has no WCAG accessibility auditing, no Core Web Vitals measurement, no technical SEO audit of websites using KeyCDN for delivery, and no ADA compliance monitoring at any price tier |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — KeyCDN is a performance CDN that caches and delivers website assets; KeyCDN has no built-in WCAG compliance checking, accessibility scoring, ADA compliance monitoring, or HTML quality analysis; KeyCDN's Image Processor API can convert images to WebP and resize them via URL parameters, but it cannot verify whether the surrounding HTML correctly implements alt text, ARIA attributes, or other WCAG 2.1 AA requirements for the images it delivers; detecting accessibility violations on websites using KeyCDN for asset delivery requires an external audit tool that scans the live rendered HTML |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — KeyCDN provides no SEO audit of websites it delivers; KeyCDN analytics show bandwidth consumption, cache hit ratio, request counts, and geographic distribution of traffic — not the SEO quality of the HTML pages being cached and delivered; KeyCDN's real-time analytics dashboard shows CDN performance data but does not analyze meta tag completeness, heading hierarchy, canonical URL correctness, structured data validity, or other technical SEO factors of the web pages delivered through KeyCDN zones |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — KeyCDN analytics measure CDN-layer performance metrics such as response time (TTFB), cache hit ratio, bandwidth, and request volume; KeyCDN does not measure browser-side Core Web Vitals (LCP, CLS, FCP, INP) as experienced by real users rendering pages delivered through KeyCDN; KeyCDN's HTTP/2 push, Brotli compression, and image optimization can contribute to improved page load performance, but measuring the actual browser-level Core Web Vitals improvement requires external performance testing tools that run the full page render including JavaScript execution |
| Global CDN with 40+ PoPs | No — PageGuard is an external monitoring tool, not a CDN or asset delivery service | ✓ Yes — KeyCDN's core value proposition: performance-optimized asset delivery through 40+ global PoPs; KeyCDN Pull Zones: configure your origin server URL, KeyCDN automatically caches and delivers your static assets globally with cache-control header respect, instant purge API, and Shield PoP to reduce origin load; KeyCDN Push Zones: upload files directly to KeyCDN storage (similar to S3) and deliver via CDN URL without an origin server; KeyCDN Image Processor: resize, crop, convert to WebP, set quality level via URL query parameters (e.g. ?width=800&height=600&format=webp&quality=80) on images stored in Push Zones; KeyCDN supports Let's Encrypt SSL, custom SSL, CNAME routing, hotlink protection, and IP blocking; KeyCDN's usage-based pricing makes it cost-effective for variable-traffic websites compared to fixed-price CDNs |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — KeyCDN does not perform automated front-end quality monitoring of WCAG compliance, Core Web Vitals, or SEO quality for websites it delivers; KeyCDN provides a real-time analytics dashboard showing CDN performance metrics but does not monitor HTML accessibility regressions, Core Web Vitals degradation, or SEO issues on the web pages delivered through KeyCDN zones; automated front-end quality monitoring of websites using KeyCDN requires a separate external monitoring tool |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — KeyCDN provides no AI-generated health report or plain-English explanation of front-end accessibility, SEO, or Core Web Vitals issues for websites using KeyCDN; the KeyCDN dashboard shows CDN performance analytics, billing, and zone configuration — not front-end quality analysis of the web pages being delivered |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — KeyCDN does not audit or alert on WCAG compliance for websites delivered through KeyCDN zones; government agencies, nonprofits, and educational institutions using KeyCDN to deliver website assets face ADA Title II compliance requirements with an April 24, 2026 deadline; KeyCDN's Image Processor can serve WebP images and optimize file sizes, but cannot verify whether HTML pages correctly implement alt text on the images it delivers; an accessibility regression (missing alt text, broken heading, removed skip link) in HTML delivered through KeyCDN will be served immediately to all users without any KeyCDN alert or detection |
| Works on any deployed platform | ✓ Yes — scans any URL on any hosting or platform | KeyCDN delivers assets for websites hosted on any platform (WordPress, custom servers, Netlify, cloud hosting) through KeyCDN Pull or Push Zone URLs; KeyCDN does not scan or monitor the front-end quality of the web pages that use its CDN delivery zones; KeyCDN is exclusively an asset delivery and caching network with no web page health monitoring capabilities |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — KeyCDN provides no built-in tool to generate a shareable external front-end health report for websites using KeyCDN; the KeyCDN dashboard and API provide CDN analytics, zone configuration, cache purge controls, and billing — not WCAG accessibility scores or Core Web Vitals quality scores shareable with clients, procurement teams, or ADA compliance auditors |
| Instant on-demand scan | ✓ Yes — results in 30 seconds, no code changes needed | No — no on-demand front-end health scan of websites using KeyCDN; auditing a KeyCDN-backed website for WCAG accessibility, Core Web Vitals, or SEO quality requires running third-party tools against the public URL; KeyCDN has no concept of scanning the HTML quality or accessibility compliance of web pages delivered through its CDN zones |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | KeyCDN's dashboard manages multiple CDN zones across an account; there is no cross-website front-end health dashboard showing WCAG compliance, SEO quality, or Core Web Vitals for multiple websites using KeyCDN as their CDN delivery layer |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Front-end health monitoring not available — KeyCDN usage-based pricing from $0.04/GB (North America/Europe), $0.10/GB (Asia-Pacific), $0.15/GB (India), $0.25/GB (Africa); minimum ~$49/year; no WCAG or Core Web Vitals monitoring at any tier |
Get WCAG accessibility scores and Core Web Vitals for any website using KeyCDN for delivery. Checks alt text, CLS from missing image dimensions, and overall page health. Results in 30 seconds. No KeyCDN account, API key, or zone credentials required.
Results in ~30 seconds. 4 scores: Performance, Accessibility, SEO, Best Practices.
Yes — PageGuard scans any public URL regardless of whether assets are served from KeyCDN, Fastly, Cloudflare, or any other CDN. Paste your website URL into PageGuard for a full health report covering WCAG accessibility, Core Web Vitals, SEO, and best practices in ~30 seconds. PageGuard checks whether images delivered through KeyCDN zones have proper alt text, whether missing width/height attributes cause CLS, and whether the overall page meets WCAG 2.1 AA. No KeyCDN account, API key, or zone credentials required.
No — KeyCDN is a performance-focused content delivery network that caches and delivers website assets through 40+ global PoPs. It has no built-in WCAG compliance checking, accessibility scoring, or ADA compliance monitoring for web pages delivered through KeyCDN zones. KeyCDN's Image Processor converts images to WebP and resizes them via URL parameters, but cannot verify whether HTML pages implement correct alt text or ARIA attributes for those images. Detecting WCAG violations on live production pages delivered through KeyCDN requires an external audit tool like PageGuard.
Yes — using KeyCDN for fast asset delivery does not automatically make a website WCAG 2.1 AA compliant. WCAG compliance is determined by the HTML, CSS, and JavaScript rendered in the browser, not by the CDN delivering those files. Images delivered through KeyCDN zones still need correct alt text (WCAG 1.1.1). Missing width and height attributes on images — even WebP images optimized by KeyCDN's Image Processor — cause Cumulative Layout Shift (CLS), a Core Web Vitals failure. PageGuard detects these issues by auditing the live rendered HTML, including all assets served through KeyCDN zone URLs.
No — they serve completely different purposes. KeyCDN is a performance content delivery network that delivers website assets through 40+ global PoPs with HTTP/3, Brotli compression, TLS 1.3, usage-based pricing from $0.04/GB, Pull Zones for origin caching, Push Zones for CDN storage, and an Image Processor API for WebP conversion. PageGuard is an external quality monitoring tool that audits the front-end HTML of deployed web pages for WCAG compliance, Core Web Vitals, and SEO quality. Organizations using KeyCDN for performance-optimized asset delivery should also use PageGuard to verify that their HTML pages correctly implement accessibility requirements that a CDN layer cannot enforce.
