Deno Deploy is a serverless edge platform for JavaScript/TypeScript apps — but as a deployment runtime, it has no built-in WCAG accessibility audit, no Core Web Vitals scoring, and no front-end health monitoring. PageGuard audits the live URL of any Deno Deploy application externally — free, no API keys 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 deploying applications on Deno Deploy face this compliance deadline. Deno Deploy’s edge architecture deploys to 35+ global regions simultaneously — any Fresh Island component change, route handler update, or middleware modification can push front-end accessibility regressions worldwide instantly with no automated quality gate. PageGuard provides continuous post-deployment front-end monitoring without requiring Deno account access or code changes.
| Feature | PageGuard | Deno Deploy |
|---|---|---|
| What is it? | External website health monitor — scans any URL for performance, accessibility, SEO, and best practices | Serverless edge deployment platform by the Deno team for JavaScript/TypeScript applications; runs Deno scripts at the edge across 35+ regions; built-in KV storage, Queues, Cron, WebSockets; no cold starts; Isolate Cloud architecture; free tier with 1M requests/month; part of the Deno runtime ecosystem (~93K GitHub Stars for Deno runtime); Deno Deploy launched GA in 2022 |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | Yes — Deno Deploy free tier includes 1M requests/month, 100GB data transfer, 512MB KV storage, custom domains; paid plans start at $20/month for higher limits; no credit card required for free tier |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — Deno Deploy is a serverless edge deployment platform; it deploys and runs Deno/TypeScript applications at the edge but has no built-in WCAG or ADA accessibility auditing for the front-end HTML output of deployed applications; accessibility quality is entirely determined by the application code deployed |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — Deno Deploy provides no SEO audit scores, meta tag validation, heading hierarchy checks, or structured data analysis; it deploys serverless edge functions but does not inspect or audit application output |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — Deno Deploy provides no Core Web Vitals measurement (LCP, CLS, FCP, INP) for deployed applications; it manages edge function execution across 35+ global regions but does not measure front-end rendering performance from a user perspective |
| Deploy serverless edge functions | No — PageGuard is a monitoring tool, not a deployment tool | ✓ Yes — Deno Deploy deploys JavaScript/TypeScript to V8 Isolates at the edge globally in 35+ regions; no cold starts (Isolate Cloud); built-in Deno.openKv() for KV storage; Deno Queues for background jobs; Deno.cron() for scheduled tasks; native WebSockets; automatic HTTPS with custom domains; GitHub integration for automatic deployments; preview deployments for each PR; playground for instant testing |
| Edge-native architecture | No — PageGuard is a centralized SaaS monitoring service | ✓ Yes — Deno Deploy runs code at the edge near users with Isolate Cloud (V8 isolates instead of containers); no container cold starts; sub-millisecond startup times; built-in Deno KV (globally replicated key-value store with strong consistency); supports Deno's native APIs (Fetch, Web Streams, Web Crypto, URLPattern); works with Fresh framework (Deno's web framework) for full-stack edge apps |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — Deno Deploy has no post-deployment front-end health monitoring for WCAG compliance, Core Web Vitals regressions, SEO quality, or best practices for rendered HTML; deployment logs and metrics track invocation counts and errors — not front-end quality |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — no front-end health report for applications deployed on Deno Deploy |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — Deno Deploy does not audit or alert on WCAG compliance for deployed apps; government agencies, nonprofits, and educational institutions deploying web applications on Deno Deploy face ADA Title II compliance requirements; each deployment can push accessibility regressions to 35+ edge regions instantly with no quality gate; TypeScript/Deno applications using Fresh or other frameworks can introduce ARIA issues, keyboard navigation gaps, and missing alt text with every code push |
| Works on any platform | ✓ Yes — scans any URL on any front-end or platform | No — Deno Deploy only manages applications deployed to its own edge infrastructure; it does not audit sites hosted elsewhere |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — no built-in tool to generate a shareable external front-end health report for a Deno Deploy application |
| Instant on-demand scan | ✓ Yes — results in 30 seconds, no code changes needed | No — no on-demand front-end health scan; auditing Deno Deploy applications requires separate tools like Lighthouse or axe after each deployment |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | Deno Deploy dashboard shows deployments, request metrics, and KV storage across projects; there is no health monitoring dashboard showing WCAG accessibility, SEO, and Core Web Vitals scores across multiple deployed applications |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Health monitoring not available — Deno Deploy free tier: 1M requests/month; paid plans from $20/month for compute; front-end health monitoring requires a separate tool |
Get WCAG accessibility scores and Core Web Vitals for any Deno Deploy application. Results in 30 seconds. No API keys, Deno account access, or code changes required.
Results in ~30 seconds. 4 scores: Performance, Accessibility, SEO, Best Practices.
Yes — PageGuard scans the live URL of any Deno Deploy application. Enter your app’s .deno.dev URL or custom domain and receive a full health report in ~30 seconds covering Core Web Vitals, WCAG 2.1 AA accessibility, technical SEO, and best practices. No API keys, Deno account access, or application code is required.
No — Deno Deploy is a serverless edge platform with no built-in WCAG compliance checking. It runs Deno/TypeScript applications at the edge across 35+ global regions but does not audit the front-end HTML output for accessibility issues. Common problems in Deno Deploy applications include missing alt text on images, improper heading hierarchy in Fresh templates, insufficient color contrast in CSS, missing ARIA labels, and keyboard navigation gaps in Island components. PageGuard audits your live Deno Deploy application and provides a WCAG 2.1 AA score with specific issues to fix.
Deno Deploy’s edge architecture deploys to 35+ global regions simultaneously — any front-end accessibility regression is instantly live worldwide with no automated quality gate. Government agencies, nonprofits, and universities deploying on Deno Deploy face ADA Title II compliance with an April 24, 2026 deadline. Fresh Island component changes, route handler updates, and middleware modifications can introduce WCAG violations globally in seconds. PageGuard provides continuous post-deployment monitoring with email alerts when WCAG scores drop.
No — they serve completely different purposes. Deno Deploy is a serverless edge platform that runs JavaScript/TypeScript across 35+ global regions with V8 Isolate Cloud architecture and no cold starts. PageGuard is an external quality monitoring tool for the front-end output of those deployed applications. Teams using Deno Deploy for hosting should add PageGuard to continuously verify WCAG compliance, Core Web Vitals, and SEO quality after each deployment.
