CDN77 is a fast-growing global CDN with 30+ PoPs, popular with media companies and game studios for high-throughput video delivery — but as delivery infrastructure it has no WCAG accessibility audit of delivered pages, no Core Web Vitals scoring, and no post-deployment front-end quality monitoring. PageGuard audits any CDN77-delivered website externally — free, no CDN access needed, results in 30 seconds.
ADA Title II Deadline: April 24, 2026
Government agencies, media organizations, public universities, and nonprofits delivering websites through CDN77 face ADA Title II compliance requirements. CDN77 delivers web pages to global users at edge speed — but cannot enforce that the HTML it caches implements correct alt text (WCAG 1.1.1), ARIA landmarks, keyboard navigation, or color contrast. An accessibility regression propagated to CDN77’s edge cache is immediately served to global users with no CDN77 alert or detection. PageGuard monitors any CDN77-delivered website for WCAG compliance without requiring CDN access or configuration changes.
PageGuard vs CDN77 — content delivery network infrastructure vs deployed website quality monitoring
| Feature | PageGuard | CDN77 |
|---|---|---|
| What is it? | External website health monitor — scans any deployed URL for performance, accessibility, SEO, and best practices | CDN77 is a Prague-based global Content Delivery Network provider founded in 2011 and operated by DataCamp Limited; CDN77 operates 30+ PoPs (Points of Presence) across North America, Europe, Asia-Pacific, and South America and is particularly recognized for its media streaming CDN capabilities and strong European presence; CDN77 delivers static and dynamic web content (HTML, CSS, JavaScript, images, video, downloads) to end users from geographically distributed edge servers, reducing latency by serving content from the PoP closest to the user; CDN77 supports HTTP/2, HTTP/3 (QUIC), Brotli and gzip compression, TLS 1.3, WebSockets, image optimization, token authentication, hotlink protection, custom SSL, and real-time origin shield configurations; CDN77 is used by media companies, broadcasters, game studios, and software distributors for high-throughput video streaming and large file downloads; CDN77 is exclusively a content delivery infrastructure layer and has no capability to audit the content it delivers for WCAG accessibility compliance, Core Web Vitals quality, or technical SEO correctness |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | CDN77 does not offer a free tier; CDN77 pricing is pay-as-you-go based on traffic volume with rates varying by region (approximately $0.049–$0.069/GB for standard traffic); CDN77 also offers custom enterprise contracts for high-volume media delivery; at no CDN77 price tier does the service include WCAG accessibility auditing, Core Web Vitals measurement, or technical SEO analysis of the content it delivers |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — CDN77 is a content delivery network infrastructure layer; it has no built-in WCAG compliance checking, accessibility scoring, or ADA compliance monitoring for the web pages it delivers; CDN77 serves cached copies of web content from edge servers closest to users — it does 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; CDN77 can deliver perfectly accessible web pages or catastrophically inaccessible ones with equal edge performance — accessibility is determined entirely by the origin server's HTML content, not by the CDN |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — CDN77 provides no SEO audit of the web content it delivers; CDN77 can be configured to set HTTP response headers (Cache-Control, Vary, X-Frame-Options), enforce HTTPS redirects, configure custom 404/error pages, and set cache TTLs — but these are CDN infrastructure configurations, not content-level SEO audits; CDN77 does not analyze the meta title, meta description, heading hierarchy, canonical URL tag, structured data markup, or internal link quality of the HTML pages delivered from its edge nodes; CDN77's analytics report traffic volume, cache hit ratios, bandwidth consumption by region, and HTTP status codes — not whether the delivered HTML page has a missing title tag or duplicate H1 |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — CDN77 does not directly measure browser-side Core Web Vitals (LCP, CLS, FCP, INP) for pages it delivers; CDN77 contributes to perceived performance through edge caching reducing TTFB, HTTP/2 multiplexing reducing connection overhead, Brotli/gzip compression reducing transfer size, HTTP/3 (QUIC) reducing latency on unreliable connections, and image optimization reducing payload size — but these CDN-side optimizations do 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 CDN77's delivery infrastructure scope |
| Content delivery network (CDN) | No — PageGuard is an external monitoring tool, not a CDN or content delivery infrastructure | ✓ Yes — CDN77 is the core value proposition: a global CDN with 30+ PoPs delivering content at low latency from geographically distributed edge servers; supports HTTP/2 and HTTP/3 (QUIC) for multiplexed, low-latency connections; Brotli and gzip compression; TLS 1.3 with custom SSL certificate support; origin shield (mid-tier caching layer reducing origin load); image optimization and WebP conversion; token authentication protecting premium content streams; hotlink protection via referer-based ACLs; real-time statistics and logs; DDoS protection; particularly well-regarded for high-throughput video streaming and large file downloads for media, gaming, and software distribution customers; pay-as-you-go pricing without minimum commitments |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — CDN77 does not perform automated front-end quality monitoring of WCAG compliance, Core Web Vitals, or SEO quality for content it delivers; CDN77's analytics dashboard provides real-time and historical traffic metrics (bandwidth, requests, cache hit rate, HTTP status codes, traffic by country and PoP) — but these monitor CDN infrastructure performance, not the HTML content quality, accessibility compliance, or SEO correctness of delivered pages; CDN77 access logs record edge request data but contain no information about whether the delivered HTML meets WCAG requirements |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — CDN77 provides no AI-generated health report or plain-English explanation of front-end accessibility, SEO, or Core Web Vitals issues for content it delivers; CDN77's reporting focuses on CDN infrastructure metrics — bandwidth consumed, cache hit ratios, geographic traffic distribution — not content-level quality issues in the HTML delivered to browsers |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — CDN77 does not audit or alert on WCAG compliance for pages it delivers; government agencies, media organizations, public universities, and nonprofits using CDN77 for content delivery face ADA Title II compliance requirements with an April 24, 2026 deadline; CDN77 delivers their web pages to global users at edge speed — but whether those pages implement correct alt text, keyboard navigation, ARIA roles, sufficient color contrast, or focus management is determined entirely by the origin HTML, not by the CDN; an accessibility regression deployed to origin and propagated to CDN77's edge cache — a missing form label, broken skip navigation link, insufficient button contrast — is immediately served to global users at full CDN speed with no CDN77 alert or detection; CDN77's role is to deliver the cached content efficiently, not to validate its accessibility |
| Works on any deployed platform | ✓ Yes — scans any URL on any hosting or platform | CDN77 delivers content for websites using its CDN infrastructure; it does not scan or monitor the front-end quality of web pages it delivers; PageGuard audits any URL regardless of whether it is served through CDN77, Cloudflare, Fastly, Akamai, KeyCDN, or any other CDN or hosting platform |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — CDN77 provides no built-in tool to generate a shareable external front-end health report for websites it delivers; CDN77's analytics dashboard shows CDN performance metrics (bandwidth, cache hit rate, traffic by geography) but is an internal operations tool, not a client-shareable accessibility or SEO quality report |
| Instant on-demand scan | ✓ Yes — results in 30 seconds, no code changes needed | No — no on-demand front-end health scan of websites delivered through CDN77; auditing a CDN77-delivered website for WCAG accessibility, Core Web Vitals, or SEO quality requires running third-party tools against the public URL; CDN77 has no built-in concept of on-demand accessibility or quality scanning of the content it delivers from its edge nodes |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | CDN77 manages multiple CDN resources (zones) from a single account with per-zone traffic analytics; there is no cross-website front-end health dashboard showing WCAG compliance, SEO quality, or Core Web Vitals for multiple websites delivered through CDN77 |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Front-end health monitoring not available — CDN77: pay-as-you-go (~$0.049–$0.069/GB) + custom enterprise; no WCAG or Core Web Vitals monitoring at any tier |
Get a full WCAG accessibility, Core Web Vitals, and SEO report in 30 seconds — free, no CDN77 access required.
Yes — PageGuard scans any public URL regardless of the CDN or infrastructure delivering it, including websites delivered through CDN77’s global edge network. Paste the public URL of your CDN77-delivered website into PageGuard for a full health report covering WCAG 2.1 AA accessibility, Core Web Vitals performance, technical SEO quality, and best practices in about 30 seconds. No CDN77 account access, configuration changes, or infrastructure credentials required.
No — CDN77 is a content delivery network infrastructure layer. It has no built-in WCAG compliance checking, accessibility scoring, or ADA compliance monitoring for the web pages it delivers. CDN77 serves cached copies of web content from edge servers closest to users — it does not parse or validate the HTML content of those responses for missing alt text, ARIA landmark structure, keyboard navigability, or color contrast. Detecting WCAG violations on a CDN77-delivered website requires an external audit tool like PageGuard.
Yes — websites delivered through CDN77 face the same WCAG and ADA compliance requirements as websites on any other CDN or hosting infrastructure. CDN77 delivers web content from its global edge network at low latency but performs no accessibility validation of the HTML content it serves. Government agencies, media organizations, and nonprofits using CDN77 face ADA Title II compliance requirements with an April 24, 2026 deadline. An accessibility regression propagated to CDN77’s edge cache — missing alt text, broken keyboard navigation, insufficient color contrast — is immediately served to global users at full edge speed with no CDN77 alert or detection. PageGuard detects these issues by auditing the live rendered HTML of the public URL.
No — they serve completely different purposes. CDN77 is a global content delivery network that accelerates website performance by caching and delivering content from edge servers closest to users, with particular strength in media streaming and large file delivery. PageGuard is an external quality monitoring tool that audits deployed web pages for WCAG accessibility compliance, Core Web Vitals performance, and technical SEO quality. Organizations using CDN77 should also use PageGuard to verify that the pages CDN77 delivers meet WCAG requirements — accessibility that CDN77 cannot enforce on the origin HTML content it caches and distributes.
