SaaS custom domain routing vs website health monitoring. Cloudflare for SaaS manages custom hostnames — PageGuard audits whether the apps served at those domains are accessible, fast, and SEO-ready.
Scan Your Website Free →💡 Tip: Use both — Cloudflare for SaaS for multi-tenant domain infrastructure, PageGuard for monitoring front-end accessibility and quality across tenant domains.
PageGuard vs Cloudflare for SaaS — what each tool actually does
| Feature | PageGuard | Cloudflare for SaaS |
|---|---|---|
| What is it? | External website health monitor — scans any deployed URL for performance, accessibility, SEO, and best practices | Cloudflare for SaaS (also known as Cloudflare Custom Hostnames) is a Cloudflare platform feature that enables SaaS companies to let their customers bring their own custom domains to the SaaS product; a SaaS vendor that uses Cloudflare for SaaS becomes a 'SaaS provider zone' — their customers can point their own apex domains (e.g., app.customer.com) to the vendor's Cloudflare-managed origin without the customer needing their own Cloudflare account; Cloudflare for SaaS handles SSL certificate provisioning (Universal or Advanced SSL per custom hostname), routing, and edge caching for all customer custom domains; it is part of Cloudflare's Workers for Platforms and Cloudflare for Platforms ecosystem targeting multi-tenant SaaS architectures; Cloudflare for SaaS does not perform WCAG accessibility audits, Core Web Vitals measurement, or technical SEO analysis on the hosted applications |
| Free tier | Yes — unlimited one-off scans, no signup required | Cloudflare for SaaS includes 100 free custom hostnames per Cloudflare zone under the free plan, with additional custom hostnames priced at $0.10/month each; however this is infrastructure pricing for domain routing — it has nothing to do with website health monitoring; Cloudflare for SaaS does not include WCAG accessibility auditing, Core Web Vitals measurement, or SEO checking at any pricing tier |
| Accessibility audit (WCAG / ADA) | Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — Cloudflare for SaaS is a custom hostname routing and SSL provisioning service; it has no WCAG compliance checking, accessibility scoring, or ADA compliance monitoring capability; Cloudflare for SaaS routes HTTP requests from customer custom domains to the SaaS provider's origin and handles SSL termination — it does not inspect or validate the HTML content delivered through those routes for accessibility compliance; a multi-tenant SaaS application running on Cloudflare for SaaS can still fail WCAG 2.1 AA requirements with missing alt text, broken keyboard navigation, insufficient color contrast, and improper ARIA implementation regardless of whether custom hostname routing is working correctly |
| Core Web Vitals | Yes — LCP, CLS, FCP, TBT, Speed Index, TTI measured per scan | No — Cloudflare for SaaS does not expose Core Web Vitals measurements; the platform handles edge routing and SSL but does not measure page load performance from the end user's perspective; Cloudflare's broader ecosystem includes Browser Insights and Speed features on paid plans but these require the customer's zone to have Cloudflare proxying enabled — they are separate from Cloudflare for SaaS custom hostname routing and do not apply to tenant custom domains managed through the SaaS provider zone; PageGuard measures actual CWV numbers on every scan |
| SEO audit | Yes — meta tags, Open Graph, canonical URLs, structured data, hreflang, robots.txt compliance checked | No — Cloudflare for SaaS does not perform SEO audits; it handles custom domain routing at the edge but does not inspect meta title content, canonical tag correctness, Open Graph images, structured data validity, or robots.txt compliance for the applications served through those custom domains; SEO health of a SaaS application using Cloudflare for SaaS is entirely determined by the application's HTML output — not by the routing layer |
| Performance score (0–100) | Yes — Lighthouse-powered composite score updated on every scan | No — Cloudflare for SaaS does not provide a Lighthouse-style performance score; the platform's value proposition is reliable custom domain routing, automatic SSL renewal, and edge caching for multi-tenant SaaS — not front-end performance measurement or scoring |
| Best practices check | Yes — HTTPS, HTTP/2, deprecated APIs, console errors, safe browsing flagged | Partial — Cloudflare for SaaS automatically provisions and renews SSL certificates for all custom hostnames (enforcing HTTPS) and delivers content over HTTP/2 and HTTP/3 at Cloudflare's edge; however it does not report on deprecated JavaScript APIs, browser console errors, mixed content warnings in page HTML, or any Lighthouse Best Practices audit items |
| Custom hostname routing | No — PageGuard scans URLs but does not manage domain routing | Yes — Cloudflare for SaaS is the leading solution for multi-tenant SaaS custom domain management; it supports apex domain routing (no CNAME flattening limitations), wildcard hostnames, per-hostname WAF and cache policies (via Custom Hostname Workers), automatic Universal SSL or Advanced Certificate Manager certificates, fallback origins, and hostname-level analytics; major platforms including Shopify (customer storefronts), Netlify (custom domains), Vercel (custom domains), and hundreds of SaaS companies use Cloudflare for SaaS for custom hostname infrastructure |
| SSL certificate provisioning | No | Yes — Cloudflare for SaaS automatically provisions DV SSL certificates for each customer custom hostname using Cloudflare's certificate authority partnerships; certificates are issued within minutes of DNS delegation and auto-renewed before expiry; SaaS providers can also use Advanced Certificate Manager for custom certificate policies, certificate pinning, and extended validation certificates |
| Edge caching for tenants | No | Yes — Cloudflare for SaaS extends Cloudflare's global CDN (300+ PoPs in 100+ countries) to all custom hostnames; each tenant's custom domain benefits from Cloudflare's cache layer, serving static assets from the edge nearest to the end user; SaaS providers can configure per-hostname cache rules using Cache Rules and Custom Hostname Workers to customize caching behavior for individual tenants |
| ADA compliance alerts | Yes — automated alerts when accessibility score drops below threshold; ADA Title II urgency tracking | No — Cloudflare for SaaS does not monitor or alert on WCAG accessibility score changes; Cloudflare for SaaS alerting covers certificate issuance failures, custom hostname validation errors, and edge routing issues — it cannot detect ADA compliance degradation in the HTML delivered through custom hostnames |
| Multi-tenant architecture support | Scans any URL — can audit individual tenant custom domains one at a time | Yes — Cloudflare for SaaS is purpose-built for multi-tenant SaaS at scale; a single SaaS provider zone can manage thousands of customer custom hostnames; Cloudflare's API enables programmatic provisioning of new custom hostnames as customers onboard; per-hostname configuration via Custom Hostname Workers enables tenant-specific routing, authentication, and caching logic |
| Primary use case | Monitor and improve website quality — accessibility compliance, performance, SEO health, best practices | Enable SaaS platforms to offer custom domain support to customers — routing customer-owned domains to the SaaS provider's infrastructure with automatic SSL, edge caching, and Cloudflare's global network |
