Convex is a reactive TypeScript backend with real-time query subscriptions, cloud functions, and a document database — but as a backend platform it has no WCAG accessibility audit, no Core Web Vitals scoring, and no front-end health monitoring for React apps built on it. PageGuard audits the live URL of any Convex-powered web application externally — free, no API credentials 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 using Convex as their backend for public-facing web applications face this compliance deadline. Convex’s reactive backend automatically pushes live data to React components but has no front-end WCAG quality gate — each frontend deployment can introduce ARIA violations, color contrast failures, and focus management regressions without any accessibility check from the Convex platform. Convex’s real-time query re-runs that trigger DOM updates can disrupt ARIA live regions and screen reader announcements if React components are not carefully implemented. PageGuard provides continuous post-deployment front-end monitoring without requiring Convex API credentials or project access.
| Feature | PageGuard | Convex |
|---|---|---|
| What is it? | External website health monitor — scans any URL for performance, accessibility, SEO, and best practices | Reactive TypeScript backend platform providing real-time queries, mutations, scheduled functions, file storage, and vector search; uses a document database (not SQL); all backend logic written as TypeScript functions running on Convex cloud infrastructure; automatic real-time reactivity — queries re-run and push updates to clients when underlying data changes; 22K+ GitHub Stars; free tier available; Pro from $25/month; used by thousands of startups and developer teams |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | Convex free tier includes 1 million function calls/month, 1 GB database storage, 1 GB file storage, 1 GB bandwidth, 25 scheduled functions; no credit card required; Pro plan from $25/month with higher limits and advanced features; no self-hosted option — Convex is cloud-only |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — Convex is a backend platform that provides a reactive document database, TypeScript cloud functions, file storage, and vector search; it provides no built-in WCAG or ADA accessibility auditing for any front-end HTML, CSS, or JavaScript output; front-end accessibility compliance is entirely determined by the React, Next.js, or SvelteKit application that subscribes to Convex queries and mutations; Convex has no awareness of how its data is rendered in the browser DOM |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — Convex provides no SEO audit scores, meta tag validation, heading hierarchy analysis, canonical URL checking, or structured data verification; Convex is a backend reactive data platform that stores and delivers application data but has no awareness of how that data is rendered into HTML for search engine indexing; all SEO quality is determined by the frontend framework consuming Convex queries |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — Convex provides no Core Web Vitals measurement (LCP, CLS, FCP, INP) for applications using its backend; Convex function execution time and query performance are server-side metrics that do not reflect front-end rendering performance experienced by real users; real-time WebSocket subscriptions can affect Time to First Byte and Largest Contentful Paint but Convex does not measure these browser-side metrics |
| Reactive backend (real-time queries) | No — PageGuard is a front-end quality monitoring tool | ✓ Yes — Convex's defining feature is automatic real-time reactivity: TypeScript query functions subscribe to database state and automatically re-run when underlying data changes, pushing live updates to React components via WebSocket without manual polling or cache invalidation; mutations update the database and automatically trigger all affected queries; this eliminates the need for separate WebSocket management, state management complexity, or manual re-fetching in React applications |
| Backend logic (TypeScript functions) | No — PageGuard is a front-end quality monitoring tool | ✓ Yes — Convex backend functions are written in TypeScript and run on Convex cloud infrastructure: queries (read-only, automatically reactive), mutations (transactional writes), actions (external API calls, non-transactional side effects), and scheduled functions (cron jobs, delayed execution); all functions are type-safe end-to-end with generated TypeScript types shared between frontend and backend; automatic serialization/deserialization of function arguments and return values |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — Convex monitors backend health (function execution times, database read/write throughput, scheduled function status, exception rates) and provides dashboard observability; Convex does not perform automated front-end quality monitoring for WCAG compliance, Core Web Vitals regressions, SEO quality, or best practices for the rendered HTML output of web applications built on Convex |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — no front-end health report or AI-generated accessibility analysis for applications built with Convex; Convex does provide vector search integration for building AI-powered search and retrieval-augmented generation features in applications, but no accessibility reporting |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — Convex does not audit or alert on WCAG compliance for applications built on its backend; government agencies, nonprofits, and educational institutions using Convex for public-facing web applications face ADA Title II compliance requirements with an April 24, 2026 deadline; React and Next.js applications subscribing to Convex real-time queries can introduce ARIA violations, color contrast failures, missing alt text on files from Convex storage, keyboard navigation gaps, and focus management issues with each frontend deployment — Convex's backend reactive engine has no front-end quality gate; Convex's automatic query re-runs that push live DOM updates to React components can disrupt screen reader announcements and ARIA live region behavior if not carefully implemented |
| Works on any platform | ✓ Yes — scans any URL on any front-end or platform | Convex is a cloud-only backend platform; it does not monitor or audit front-end applications built with non-Convex backends |
| 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 an application built on Convex |
| Instant on-demand scan | ✓ Yes — results in 30 seconds, no code changes needed | No — no on-demand front-end health scan; auditing web applications that use Convex as a backend requires separate tools like Lighthouse or axe-core after each frontend deployment |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | Convex provides a project dashboard for monitoring backend function activity, database state, logs, and scheduled jobs across Convex deployments; there is no cross-application front-end health monitoring showing WCAG accessibility, SEO, and Core Web Vitals scores across multiple sites |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Health monitoring not available — Convex is a backend platform; Free tier: 1M function calls/month; Pro: $25/month; Enterprise: custom; no front-end quality monitoring included at any tier |

Yes — PageGuard scans the live URL of any web application that uses Convex as its backend. Enter your app’s public 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 Convex project credentials, API keys, or application code changes are required.
No — Convex is a reactive backend platform with no built-in WCAG compliance checking. Convex provides a document database, TypeScript cloud functions, file storage, and vector search but has no awareness of how its data is rendered in the front-end DOM. Common accessibility problems in Convex-powered React applications include ARIA violations in real-time reactive components, focus management issues when Convex queries push live DOM updates, inaccessible loading states during query subscription, and keyboard navigation gaps in mutation-driven UI flows. PageGuard audits your live site and provides a WCAG 2.1 AA score with a specific list of issues to fix.
Convex’s reactive backend automatically pushes data updates to React components, but front-end accessibility quality is entirely determined by how those components render the data in the browser. Each frontend deployment can introduce WCAG violations without any check from the Convex platform. Convex’s real-time query subscriptions that trigger DOM re-renders can disrupt ARIA live regions and screen reader announcements if React components are not carefully implemented. Government agencies and nonprofits using Convex face ADA Title II requirements with an April 24, 2026 deadline. PageGuard provides continuous post-deployment accessibility monitoring with email alerts when scores drop.
No — they serve completely different purposes. Convex is a reactive TypeScript backend platform providing a document database with real-time query subscriptions, cloud functions, file storage, and vector search for building data-driven web applications. PageGuard is an external quality monitoring tool for the rendered front-end output of those applications. Teams using Convex as their backend should add PageGuard to continuously verify WCAG compliance, Core Web Vitals, and SEO quality of the frontend applications that subscribe to Convex queries.
