Amazon CloudFront is AWS’s global CDN serving content from 600+ edge locations — but as a content delivery network it has no WCAG accessibility audit, no Core Web Vitals scoring, and no post-deployment quality monitoring. PageGuard audits any CloudFront-delivered website externally — free, no AWS credentials 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 serving websites via CloudFront-backed stacks (S3+CloudFront, EC2+CloudFront, Amplify) face this compliance deadline. CloudFront cache invalidations distribute content updates to 600+ edge PoPs simultaneously — a deployment introducing ARIA violations, color contrast failures, or keyboard navigation regressions reaches users worldwide within minutes without any WCAG quality gate. PageGuard provides continuous post-deployment monitoring of the live CloudFront URL without requiring AWS credentials or IAM access.
| Feature | PageGuard | Amazon CloudFront |
|---|---|---|
| What is it? | External website health monitor — scans any deployed URL for performance, accessibility, SEO, and best practices | Amazon CloudFront is AWS's global content delivery network (CDN) and edge computing service; caches and delivers static assets (HTML, CSS, JS, images, video) from 600+ Points of Presence (PoPs) across 90+ cities in 47 countries; reduces latency by serving content from the edge location nearest each user; supports HTTP/2, HTTP/3, IPv6, Brotli compression, and TLS 1.3; integrates natively with S3 (origin), EC2, Load Balancers, API Gateway, and Amplify Hosting; Lambda@Edge and CloudFront Functions enable edge-side compute for request/response manipulation, A/B testing, authentication, and URL rewrites; Origin Shield adds a mid-tier caching layer to reduce origin load; Real-time logs and CloudWatch metrics for cache hit ratio, origin latency, and error rates; used by startups and Fortune 500 to serve billions of requests per day |
| Free tier | Yes — unlimited one-off scans, no signup required | Yes — AWS CloudFront free tier includes 1 TB data transfer out, 10 million HTTP/HTTPS requests, and 2 million CloudFront Functions invocations per month for 12 months; beyond free tier from $0.0085/GB data transfer and $0.0100/10,000 HTTPS requests (US/EU region); no front-end quality monitoring at any tier |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — Amazon CloudFront is a CDN and edge delivery network with no built-in WCAG or ADA accessibility auditing for content it delivers; CloudFront caches and serves your HTML, CSS, JavaScript, and media files as-is to end users without inspecting or scoring the WCAG accessibility compliance of the content; ARIA violations, color contrast failures, missing alt text, improper heading hierarchy, keyboard navigation gaps, and inaccessible form controls in CloudFront-delivered websites are completely invisible to CloudFront; CloudFront Reports and CloudWatch Metrics track cache hit ratio, viewer requests by protocol, error rates, and bandwidth — none of these are front-end WCAG quality metrics; accessibility quality depends entirely on the HTML and JavaScript you write and cache via CloudFront |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — Amazon CloudFront provides no SEO audit scores, meta tag validation, heading hierarchy analysis, canonical URL checking, or structured data verification for content it delivers; CloudFront can be configured to forward or strip headers and manage cache-control directives, but provides no awareness of on-page SEO quality; all SEO quality of websites delivered via CloudFront depends entirely on the HTML you generate and publish to the origin |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — Amazon CloudFront provides no Core Web Vitals measurement (LCP, CLS, FCP, INP, TTFB) for content it delivers; CloudFront metrics include origin latency (time to first byte from origin), cache hit ratio, and viewer request error rates — these are CDN infrastructure metrics, not front-end user experience quality metrics; CloudFront's low-latency delivery from edge PoPs improves TTFB for cached assets but does not measure or report the resulting LCP, CLS, FCP, or INP experienced by end users in their browsers; measuring production Core Web Vitals requires separate tooling like PageGuard, Chrome UX Report, or Google Search Console |
| Global CDN delivery | No — PageGuard is an external monitoring tool, not a CDN or hosting platform | ✓ Yes — AWS CloudFront core capability: 600+ PoPs in 90+ cities in 47 countries serving content from the nearest edge location to each viewer; supports HTTP/2, HTTP/3 (QUIC), IPv6, Brotli and Gzip compression, and TLS 1.3; Origin Shield for mid-tier caching; geo-restriction to block content by country; signed URLs and signed cookies for private content; Field-Level Encryption for PII; Lambda@Edge and CloudFront Functions for edge-side request/response manipulation with sub-millisecond latency; Real-Time Logs streaming to Kinesis Data Streams; native integration with AWS WAF (DDoS, bot protection), AWS Shield Standard (always on), and AWS Certificate Manager (free SSL) |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — Amazon CloudFront does not perform automated quality monitoring of WCAG compliance, Core Web Vitals, or SEO quality for websites it delivers; CloudFront Alarms in CloudWatch can alert on error rate spikes, origin latency thresholds, and cache hit ratio drops but provide no front-end quality regression detection for accessibility or SEO |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — Amazon CloudFront provides no AI-generated health report or plain-English explanation of front-end accessibility, SEO, or Core Web Vitals issues for websites it delivers; AWS Trusted Advisor and AWS Compute Optimizer provide AI-based recommendations for infrastructure cost and performance optimization, not front-end HTML quality |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — Amazon CloudFront does not audit or alert on WCAG compliance for websites it delivers; government agencies, nonprofits, and educational institutions serving public-facing websites via CloudFront (typically S3+CloudFront, Amplify, or EC2+CloudFront stacks) face ADA Title II compliance requirements with an April 24, 2026 deadline; CloudFront's global CDN serves HTML, CSS, and JS files without inspecting their WCAG quality; cache invalidations that push updated content to all 600+ PoPs can silently distribute accessibility regressions to end users worldwide within minutes without any quality gate |
| Works on any deployed platform | ✓ Yes — scans any URL on any hosting or platform | Amazon CloudFront delivers content for AWS-connected origins (S3, EC2, API Gateway, Amplify, Load Balancers, or custom HTTP origins); it does not scan or monitor websites hosted on Netlify, Vercel, Cloudflare Pages, or other CDN platforms |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — Amazon CloudFront provides no built-in tool to generate a shareable external front-end health report for a website delivered via its CDN; CloudFront console shows deployment status, cache behavior settings, distribution metrics, and access logs but no WCAG accessibility score or SEO quality score shareable with clients, procurement teams, or 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 delivered via CloudFront; auditing a CloudFront-delivered website for WCAG accessibility, Core Web Vitals, or SEO quality requires running separate third-party tools (PageGuard, Lighthouse, axe) against the CloudFront distribution domain or custom domain after deployment |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | Amazon CloudFront console shows all CloudFront distributions with their origins, cache behaviors, and performance metrics; there is no cross-distribution health dashboard showing WCAG compliance, SEO quality, or Core Web Vitals for all delivered websites |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Health monitoring not available — CloudFront pricing: free tier 1 TB/month data transfer + 10M requests for 12 months; then $0.0085/GB (US/EU), $0.120/GB (India), $0.170/GB (Australia); $0.0100–$0.0160/10,000 HTTPS requests by region; Lambda@Edge $0.60/million requests + $0.00000625001/GB-second; CloudFront Functions $0.10/million invocations; no front-end quality monitoring at any price |

Yes — PageGuard scans any public URL regardless of the CDN infrastructure behind it. Paste your CloudFront distribution domain (*.cloudfront.net) or custom domain into PageGuard for a full health report covering WCAG accessibility, Core Web Vitals, SEO, and best practices in ~30 seconds. No AWS account or IAM credentials required.
No — Amazon CloudFront is a CDN with no built-in WCAG compliance checking for content it delivers. CloudFront Metrics track cache hit ratio, origin latency, and error rates — not front-end WCAG quality. PageGuard audits the live CloudFront-delivered URL directly and provides a WCAG 2.1 AA score with specific issues to fix.
CloudFront cache invalidations push content updates to 600+ edge PoPs simultaneously, meaning accessibility regressions can reach users worldwide within minutes without any quality gate. Government agencies, nonprofits, and educational institutions hosting websites on CloudFront-backed infrastructure face ADA Title II requirements with an April 24, 2026 deadline. PageGuard provides continuous post-deployment monitoring with email alerts when WCAG scores drop after cache invalidations.
No — they serve completely different purposes. Amazon CloudFront is a global CDN that delivers content from 600+ edge locations to minimize latency and provide DDoS protection. PageGuard is an external quality monitoring tool that audits the delivered content for WCAG compliance, Core Web Vitals, and SEO quality. Teams using CloudFront for delivery should add PageGuard to continuously verify front-end health at the production edge URL.
