Cloudflare R2 can host static websites from R2 buckets with zero egress fees — but as an object storage service it has no WCAG accessibility audit, no Core Web Vitals scoring, and no post-deployment front-end quality monitoring. PageGuard audits any R2-hosted website externally — free, no Cloudflare 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 hosting public-facing static websites in Cloudflare R2 buckets face this compliance deadline. Automated deployments through GitHub Actions, Workers scripts, or the Wrangler CLI can upload new HTML files to R2 buckets with accessibility regressions without any WCAG quality gate at the storage layer. PageGuard monitors the live production URL continuously without requiring Cloudflare account access, R2 API tokens, or bucket modifications.
| Feature | PageGuard | Cloudflare R2 |
|---|---|---|
| What is it? | External website health monitor — scans any deployed URL for performance, accessibility, SEO, and best practices | Cloudflare R2 is Cloudflare's S3-compatible zero-egress-cost object storage service for storing unstructured data — files, images, videos, backups, and static website assets; R2 uses the same S3 API surface developers already know (compatible with AWS SDK, rclone, s3cmd, and other S3 tooling) while eliminating the egress bandwidth charges that represent the majority of object storage costs on AWS S3, Google Cloud Storage, and Azure Blob Storage; R2 buckets can be made publicly accessible via r2.dev subdomains or custom domains tied to a Cloudflare zone, enabling static website hosting for HTML, CSS, JavaScript, and image files; R2 is deeply integrated with other Cloudflare products — Workers can read and write R2 objects directly using the R2 binding, enabling serverless applications that process uploads or serve dynamically transformed files; R2 also supports event notifications via Cloudflare Queues when objects are created or deleted; R2 does not analyze the HTML content of files it stores — it is an object store that serves bytes without understanding HTML structure, accessibility requirements, or Core Web Vitals quality |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | Partial — R2 Free Tier includes 10 GB of storage per month, 1 million Class A operations (writes) per month, and 10 million Class B operations (reads) per month with zero egress fees even after the free tier; after the free tier, Standard storage from $0.015/GB/month; no built-in WCAG accessibility auditing or Core Web Vitals measurement for websites hosted in R2 buckets at any storage tier or pricing level |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — Cloudflare R2 is an object storage service with no built-in WCAG or ADA accessibility auditing capability for websites hosted in its buckets; R2 stores and serves the HTML files uploaded to it but has no mechanism to parse, analyze, or score the accessibility quality of that HTML; R2 does not understand color contrast ratios, ARIA attribute usage, alt text presence, heading hierarchy, keyboard navigation, or any other WCAG 2.1 AA success criterion; the accessibility quality of an R2-hosted website is entirely determined by the HTML, CSS, and JavaScript files stored in the bucket — not by R2 itself |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — Cloudflare R2 provides no SEO audit scores, meta tag validation, heading hierarchy analysis, canonical URL checking, or structured data verification for HTML files stored in its buckets; R2 serves files as-is without analyzing or validating their SEO quality; developers hosting websites in R2 must use separate SEO audit tools to verify the rendered HTML served to users and search engine crawlers; R2 also does not generate or validate robots.txt or sitemap.xml files |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — Cloudflare R2 provides no Core Web Vitals measurement (LCP, CLS, FCP, INP, TTFB) for websites hosted in its buckets; R2 bucket metrics focus on request counts, object operations, and data storage — not browser-side user experience quality scores; R2 static site performance is affected by Cloudflare's global network edge and Cache Control headers set on objects — but R2 itself does not measure or report user-facing Core Web Vitals; measuring production Core Web Vitals for R2-hosted sites requires external tooling |
| Zero-egress object storage | No — PageGuard is an external monitoring tool, not an object storage or hosting service | ✓ Yes — R2 core differentiator: zero egress fees for data transferred to the internet, unlike AWS S3 ($0.09/GB), Google Cloud Storage ($0.12/GB), and Azure Blob Storage ($0.087/GB); store static website files, user uploads, media assets, and backups without bandwidth cost surprises; S3-compatible API surface works with existing tooling (AWS SDK v2/v3, rclone, s3cmd, Cyberduck, Transmit); Workers R2 binding for direct serverless access without API credentials in Workers code; Cloudflare's 300+ global PoPs serve R2 content with low latency; WORM-style object lock available; object versioning; lifecycle rules for automatic deletion |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — Cloudflare R2 does not perform automated quality monitoring of WCAG compliance, Core Web Vitals, or SEO quality for websites hosted in its buckets; Cloudflare Analytics can show R2 request counts, cache hit rates, and error rates for content served from R2 — not front-end accessibility regressions, Core Web Vitals degradation, or SEO issues in the HTML files stored in the bucket; automated front-end quality monitoring of R2-hosted websites requires a separate external monitoring tool |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — Cloudflare R2 provides no AI-generated health report or plain-English explanation of front-end accessibility, SEO, or Core Web Vitals issues; the Cloudflare R2 dashboard shows bucket storage usage, object list, access configuration, and operation metrics — not front-end quality analysis of the website content stored in the bucket |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — Cloudflare R2 does not audit or alert on WCAG compliance for HTML files stored in its buckets; government agencies, nonprofits, and educational institutions hosting public-facing static websites in R2 buckets face ADA Title II compliance requirements with an April 24, 2026 deadline; automated deployments through GitHub Actions, Workers scripts, or the Wrangler CLI can upload new HTML files to R2 buckets with accessibility regressions without any WCAG quality gate at the storage layer; continuous WCAG monitoring of the production URL requires a separate external tool like PageGuard |
| Works on any deployed platform | ✓ Yes — scans any URL on any hosting or platform | Cloudflare R2 serves content within Cloudflare's own infrastructure; it does not scan or monitor the front-end quality of websites hosted on AWS S3, Google Cloud Storage, Azure Blob Storage, Vercel, Netlify, or other storage and hosting platforms; R2 focuses exclusively on its own object storage operations without cross-platform front-end quality monitoring capability |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — Cloudflare R2 provides no built-in tool to generate a shareable external front-end health report for websites it hosts; the R2 dashboard and Cloudflare Analytics show bucket storage metrics, request logs, and infrastructure health — 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 hosted in R2 buckets; auditing an R2-hosted website for WCAG accessibility, Core Web Vitals, or SEO quality requires running third-party tools against the public bucket URL or custom domain; R2 has no concept of scanning the HTML accessibility or performance quality of the static files stored in its buckets |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | The Cloudflare R2 dashboard shows all buckets within a Cloudflare account with storage usage, object count, and access configuration — there is no cross-website front-end health dashboard showing WCAG compliance, SEO quality, or Core Web Vitals for multiple static websites hosted across R2 buckets |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Front-end health monitoring not available — R2 Standard storage from $0.015/GB/month; Class A operations (writes) from $4.50/million; Class B operations (reads) from $0.36/million; zero egress fees regardless of data volume; no front-end quality monitoring at any spend level |
Get WCAG accessibility scores and Core Web Vitals for any static website hosted on Cloudflare R2. Results in 30 seconds. No Cloudflare account access, R2 API tokens, or bucket modifications required.
Results in ~30 seconds. 4 scores: Performance, Accessibility, SEO, Best Practices.
Yes — PageGuard scans any public URL regardless of whether the website is hosted on Cloudflare R2, AWS S3, Google Cloud Storage, or any other platform. Paste your R2 website URL into PageGuard for a full health report covering WCAG accessibility, Core Web Vitals, SEO, and best practices in ~30 seconds. No Cloudflare account, R2 API tokens, or bucket modifications required.
No — Cloudflare R2 is an object storage service that stores and serves files without analyzing their content quality. It has no built-in WCAG compliance checking, accessibility scoring, or front-end quality analysis for HTML files stored in its buckets. Cloudflare Analytics tracks R2 infrastructure metrics (request counts, cache hit rates, error rates) — not browser-side user experience quality metrics. PageGuard audits the live rendered URL and provides a WCAG 2.1 AA score with specific issues to fix.
Yes — automated deployments through GitHub Actions, Workers scripts, or the Wrangler CLI that upload new HTML files to an R2 bucket can introduce WCAG accessibility regressions without any quality gate at the storage layer. Static site generators (Hugo, Jekyll, Gatsby, Eleventy, Next.js) regenerating templates can break heading hierarchy, remove alt text from images, or introduce missing ARIA labels in the generated HTML. PageGuard's automated monitoring detects these front-end regressions in the live production URL after each deployment to R2.
No — they serve completely different purposes. Cloudflare R2 is an S3-compatible object storage service that stores and serves static files with zero egress fees and high global availability via Cloudflare's 300+ PoP network. PageGuard is an external quality monitoring tool that audits the front-end HTML delivered to users for WCAG compliance, Core Web Vitals, and SEO quality. Organizations hosting websites in R2 buckets should add PageGuard to continuously verify front-end health at the production URL after each deployment.
