SolidJS is a high-performance reactive UI library with fine-grained reactivity and no virtual DOM, but as a client-side and SSR development framework it has no built-in WCAG accessibility audit, no Core Web Vitals scoring, and no post-deployment health monitoring. PageGuard audits the live production URL of any SolidJS app externally — free, no source code access required, 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. SolidJS’s fine-grained reactivity and compiled output often produce lean, fast HTML — but lean HTML does not guarantee WCAG compliance. Interactive components still require correct ARIA roles, keyboard navigation, focus management, and sufficient color contrast. Developers choosing SolidJS for performance-critical government or public-sector projects still need external WCAG auditing of the deployed production output. PageGuard audits your live SolidJS app after each deployment and alerts you to accessibility regressions before the April 24 deadline.
| Feature | PageGuard | SolidJS |
|---|---|---|
| What is it? | External website health monitor — scans any URL for performance, accessibility, SEO, and best practices | Fine-grained reactive JavaScript library for building user interfaces — compiles JSX to real DOM operations without a virtual DOM; SolidStart for full-stack SSR; 31K+ GitHub stars |
| Free tier | Yes — unlimited one-off scans, no signup required | Yes — SolidJS is open-source (MIT license) and free to use; hosting costs depend on your chosen provider |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — SolidJS has no built-in WCAG accessibility auditing of the deployed application's rendered HTML; eslint-plugin-jsx-a11y can catch some issues at build time |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — SolidJS and SolidStart provide mechanisms to set meta tags, but there is no built-in audit of the live deployed page's SEO quality |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — SolidJS's fine-grained reactivity and no virtual DOM often produce excellent real-world CWV, but SolidJS itself does not score Core Web Vitals on deployed production pages |
| Fine-grained reactive UI library | No — PageGuard is a monitoring tool, not a UI development library | ✓ Yes — fine-grained signals-based reactivity, JSX compiled to real DOM operations (no virtual DOM), automatic dependency tracking, and reactive primitives (createSignal, createEffect, createMemo) |
| Full-stack SSR / SSG | No — PageGuard is a SaaS monitoring service | ✓ Yes — SolidStart provides file-based routing, server functions, streaming SSR, and adapters for Vercel, Netlify, Cloudflare Workers, and Node.js |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — SolidJS is a UI library; it has no post-deployment health monitoring or accessibility regression alerts for production apps |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — no AI health report for rendered production page quality |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — SolidJS produces DOM output efficiently but does not audit or alert on WCAG compliance in the deployed production app; ARIA usage and keyboard navigation depend on the developer |
| Works on any platform | ✓ Yes — scans any URL on any front-end or platform | No — SolidJS is a UI library for building apps; it does not audit or monitor front-end sites built with other technologies |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — no built-in tool to generate a shareable external health report for a deployed SolidJS application |
| Instant on-demand scan | ✓ Yes — results in 30 seconds, no code changes needed | No — no on-demand health scan; external auditing of deployed SolidJS apps requires separate tools like Lighthouse or axe |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | SolidJS manages UI component state, not a multi-site health monitoring dashboard for deployed production apps |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Health monitoring not available — SolidJS is a UI library, not a front-end monitoring tool |
Get the WCAG accessibility score and Core Web Vitals that SolidJS’s build toolchain doesn’t provide for your deployed production app. Results in 30 seconds. No source code, SolidStart CLI, or developer credentials required.
Results in ~30 seconds. 4 scores: Performance, Accessibility, SEO, Best Practices.
Yes — PageGuard scans the live deployed URL of any SolidJS application, including SolidStart SSR apps hosted on Vercel, Netlify, Cloudflare Workers, or self-hosted servers. Enter the production URL and receive a full health report in ~30 seconds covering Core Web Vitals, WCAG 2.1 AA accessibility, technical SEO, and best practices. No source code, SolidStart CLI access, or developer credentials are required.
No — SolidJS compiles JSX to real DOM operations with fine-grained reactivity, which results in efficient rendered HTML. However, SolidJS does not audit WCAG compliance in the deployed production app. Accessibility quality depends on your ARIA usage in components, keyboard navigation implementation, color contrast, focus management in dynamic content, and how interactive elements behave at runtime. PageGuard audits your live SolidJS app and provides a WCAG 2.1 AA score with specific issues to fix.
SolidJS handles the UI layer: fine-grained reactive primitives, compiled JSX without a virtual DOM, and SolidStart for server-side rendering and routing. PageGuard audits the production layer: (1) WCAG/ADA accessibility of the rendered HTML your SolidJS app produces in production, (2) Core Web Vitals performance (LCP, CLS, FCP) of the deployed application, (3) technical SEO quality including meta tags set via SolidStart’s Meta API, and (4) automated monitoring with email alerts when code deployments introduce regressions — from $9/mo.
No — they serve completely different purposes. SolidJS is a reactive UI library for building high-performance web applications with fine-grained reactivity and no virtual DOM. SolidStart extends it with SSR, file-based routing, and server functions. PageGuard is an external quality monitoring tool for your deployed front-end. Teams building SolidJS apps should use both: SolidJS to build and deliver the application, PageGuard to verify the production site meets accessibility compliance and performance standards after every deployment.
