Global CDN and edge cloud vs website health monitoring. G-Core delivers your content fast from 160+ PoPs — PageGuard tells you whether that content meets WCAG, Core Web Vitals, and SEO standards.
Scan Your Website Free →💡 Tip: Use both — G-Core for global delivery and DDoS protection, PageGuard for front-end quality monitoring.
PageGuard vs G-Core Labs (Gcore) — what each platform actually does
| Feature | PageGuard | G-Core Labs (Gcore) |
|---|---|---|
| What is it? | External website health monitor — scans any deployed URL for performance, accessibility, SEO, and best practices | G-Core Labs (rebranded as Gcore in 2022) is a Luxembourg-based global edge cloud and infrastructure platform founded in 2014; G-Core offers a CDN with 160+ Points of Presence across Europe, North America, Asia-Pacific, Latin America, Africa, and the Middle East, plus DDoS protection, video streaming delivery, bare metal cloud, edge computing, and a gaming infrastructure platform; G-Core's CDN focuses on accelerating content delivery and protecting against volumetric attacks — it does not parse or validate the HTML content it delivers for WCAG accessibility compliance, Core Web Vitals quality, or technical SEO correctness; G-Core serves enterprise customers including gaming companies, media broadcasters, and e-commerce platforms seeking low-latency global delivery |
| Free tier | Yes — unlimited one-off scans, no signup required | G-Core offers a free CDN tier with 1 TB of traffic per month and access to its global PoP network, making it one of the few CDN providers with a genuinely useful free plan; however G-Core's free CDN tier — like all its paid tiers — includes no WCAG accessibility auditing, no Core Web Vitals measurement, no Lighthouse scoring, and no technical SEO checking; the free tier is infrastructure delivery only |
| Accessibility audit (WCAG / ADA) | Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — G-Core is a CDN and edge infrastructure provider; it has no WCAG compliance checking, accessibility scoring, or ADA compliance monitoring at any tier; G-Core's edge nodes receive HTTP requests, apply caching rules, route traffic to the nearest PoP, and serve cached responses to end users — they do not inspect the HTML of those responses for missing alt text (WCAG 1.1.1), insufficient color contrast (WCAG 1.4.3), absent ARIA landmarks (WCAG 1.3.1), keyboard navigation failures (WCAG 2.1.1), or any other WCAG 2.1 success criterion; G-Core can deliver accessible or inaccessible web pages with equal efficiency at 160+ global locations |
| Core Web Vitals | Yes — LCP, CLS, FCP, TBT, Speed Index, TTI measured per scan | No — G-Core does not expose Core Web Vitals measurements to customers; G-Core's CDN does improve real-world LCP and FCP by reducing TTFB through its global PoP network, but G-Core provides no dashboard showing LCP values, CLS scores, FCP timings, or any other Core Web Vitals metric for your origin content; customers must use separate tools such as PageGuard, Google PageSpeed Insights, or WebPageTest to measure whether CWV thresholds are actually met after G-Core delivery |
| SEO audit | Yes — meta tags, Open Graph, canonical URLs, structured data, hreflang, robots.txt compliance checked | No — G-Core does not perform SEO audits; G-Core's platform monitors CDN performance metrics such as hit/miss ratios, origin response times, bandwidth consumption, and PoP-level latency — it does not check meta title length, meta description presence, duplicate canonical tags, missing Open Graph images, structured data validity, or any on-page SEO factor; G-Core can be configured to respect cache-control headers and pass through proper HTTP status codes, which indirectly supports SEO, but there is no active SEO checking |
| Performance score (0–100) | Yes — Lighthouse-powered composite score updated on every scan | No — G-Core does not provide a Lighthouse-style composite performance score; G-Core's analytics dashboard shows CDN metrics including requests per second, cache hit rate, bandwidth usage by region, and error rates — these are infrastructure health metrics, not front-end performance quality scores; there is no 0–100 score, no Lighthouse Performance category equivalent, and no comparison against Google's recommended performance thresholds |
| Best practices check | Yes — HTTPS, HTTP/2, deprecated APIs, console errors, safe browsing flagged | Partial — G-Core enforces HTTPS termination at its edge nodes and supports HTTP/2 and HTTP/3 (QUIC) by default on all plans, which satisfies those specific best practices; however G-Core does not check for deprecated JavaScript APIs in page content, browser console errors, mixed content warnings in HTML, or any of the Lighthouse Best Practices audit items beyond transport security; G-Core's focus is on infrastructure configuration, not content quality analysis |
| CDN / global delivery | No — PageGuard is a monitoring tool, not a CDN | Yes — G-Core's CDN is its primary product with 160+ PoPs across all major regions; G-Core supports HTTP caching, WebSocket acceleration, image optimization, prefetch rules, and origin shielding; it is one of the most geographically diverse CDNs available, with particularly strong coverage in Eastern Europe, Central Asia, and Africa compared to Western CDN providers |
| DDoS protection | No | Yes — G-Core offers DDoS protection at layers 3, 4, and 7 with scrubbing capacity exceeding 1.5 Tbps; G-Core's DDoS mitigation is integrated directly into its CDN layer with automatic attack detection and mitigation; the platform has protected gaming, media, and financial services companies against large-scale volumetric and application-layer attacks |
| Video streaming delivery | No | Yes — G-Core has a dedicated video streaming platform supporting HLS, MPEG-DASH, and low-latency live streaming; G-Core's video CDN includes a media storage layer, transcoding, and real-time analytics for video delivery — a capability not offered by most CDN competitors at G-Core's price point |
| Edge computing | No | Yes — G-Core offers Edge Computing (Fastedge) for serverless JavaScript execution at the CDN edge, and bare metal cloud in 20+ locations for latency-sensitive workloads like gaming and financial trading; G-Core's edge compute layer supports custom logic closer to end users than traditional cloud regions |
| ADA compliance alerts | Yes — automated alerts when accessibility score drops below threshold; ADA Title II urgency tracking | No — G-Core does not monitor or alert on WCAG accessibility compliance; G-Core's alerting system covers infrastructure events such as origin health failures, traffic anomalies, and DDoS attack onsets — it does not cover accessibility regressions caused by CMS updates, new content, or theme changes that introduce WCAG violations |
| Pricing model | Free tier + Starter $9/mo · Pro $29/mo · Agency $79/mo | Free tier (1 TB/month CDN traffic) + pay-as-you-go CDN at ~$0.01–$0.05/GB depending on region; DDoS protection and edge compute are add-on products with separate pricing; G-Core's pricing favors high-traffic sites that benefit from predictable bandwidth costs |
| Primary use case | Monitor and improve website quality — accessibility compliance, performance, SEO health, best practices | Global content delivery and edge infrastructure — CDN acceleration, DDoS protection, video streaming, edge computing, and bare metal cloud for latency-sensitive applications |
