Hasura is an open-source GraphQL engine with 31K+ GitHub Stars that generates instant APIs over PostgreSQL, MySQL, and MongoDB — but as a backend API layer it has no WCAG accessibility audit, no Core Web Vitals scoring, and no front-end health monitoring for applications built on it. PageGuard audits the live URL of any Hasura-powered web application externally — free, no admin secret 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 Hasura for public-facing web applications face this compliance deadline. Hasura’s GraphQL API layer delivers data with low latency but has no front-end WCAG quality gate — React, Next.js, and Vue applications consuming Hasura’s GraphQL API can introduce ARIA violations, color contrast failures, and keyboard navigation regressions with each frontend deployment without any accessibility check from Hasura. GraphQL query responses containing CMS content, product listings, and database-driven user interface data may render as inaccessible HTML that Hasura serves without any validation. Real-time subscriptions pushing live data updates to the UI can introduce dynamic accessibility issues including focus management failures and ARIA live region misconfiguration that static HTML linting tools cannot detect. PageGuard provides continuous post-deployment front-end monitoring without requiring Hasura admin secrets or database access.
| Feature | PageGuard | Hasura |
|---|---|---|
| What is it? | External website health monitor — scans any URL for performance, accessibility, SEO, and best practices | Open-source GraphQL engine that generates instant GraphQL and REST APIs over existing databases (PostgreSQL, MySQL, SQL Server, MongoDB, BigQuery, and more) without writing backend code; connects to databases via metadata configuration and provides real-time subscriptions, role-based access control, event triggers, remote schemas, and Actions for custom business logic; 31K+ GitHub Stars; self-hostable via Docker or cloud-deployable on Hasura Cloud with a generous free tier; used by thousands of companies to rapidly build data APIs consumed by React, Next.js, Vue, Angular, and mobile frontends |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | Hasura Cloud Free tier: 60 API requests/minute, 100MB data passthrough/month, 1 admin, no SLA; Hasura Professional from $99/month; self-hosted community edition is fully free with Docker Compose but requires server management; Hasura DDN (Data Delivery Network) has a separate free tier for the v3 architecture with 3 million operations/month; no front-end quality monitoring at any tier |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — Hasura is a GraphQL/REST API engine that provides data access to databases via typed queries; it provides no built-in WCAG or ADA accessibility auditing for front-end HTML, CSS, or JavaScript output; front-end accessibility compliance is entirely determined by the React, Next.js, Vue, Angular, or mobile application that consumes Hasura's GraphQL or REST API; Hasura has no awareness of how its JSON API responses are rendered in the browser DOM or whether client-side components meet WCAG requirements; ARIA violations, color contrast failures, keyboard navigation gaps, and missing alt text on Hasura-powered content are invisible to Hasura's API layer |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — Hasura provides no SEO audit scores, meta tag validation, heading hierarchy analysis, canonical URL checking, or structured data verification; Hasura is an API gateway that delivers JSON responses to client applications but has no awareness of how those responses are rendered into HTML for search engine indexing; all SEO quality is determined by the SSR or client-side rendering layer (Next.js, Nuxt, SvelteKit, Remix) consuming Hasura's GraphQL queries |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — Hasura provides no Core Web Vitals measurement (LCP, CLS, FCP, INP) for applications using its API; Hasura's performance metrics focus on GraphQL query execution time, database connection pool utilization, and API throughput rather than browser-side rendering performance; fast Hasura API responses reduce network fetch time, which can improve TTFB, but do not directly determine LCP, CLS, or FCP scores which are affected by the full rendering pipeline including CSS, JavaScript, images, and fonts |
| Instant GraphQL & REST API over databases | No — PageGuard is a front-end quality monitoring tool | ✓ Yes — Hasura's core capability: connect Hasura to an existing PostgreSQL, MySQL, SQL Server, MongoDB, BigQuery, or other supported database and get an instant GraphQL API with auto-generated queries, mutations, and subscriptions without writing resolver code; metadata-driven configuration via YAML or the Hasura Console; role-based access control (RBAC) with row-level and column-level permissions; real-time GraphQL subscriptions via WebSockets; REST endpoints created from named GraphQL queries; Hasura Actions for custom business logic via HTTP webhooks; Remote Schemas to stitch in other GraphQL services; Event Triggers for database-driven asynchronous workflows |
| Real-time GraphQL subscriptions | No — PageGuard is a front-end quality monitoring tool | ✓ Yes — Hasura generates real-time GraphQL subscriptions that push live database updates to connected clients via WebSockets; subscription queries auto-invalidate when underlying database rows change; used in dashboards, collaborative tools, live feeds, and notification systems built with React, Vue, and React Native; subscriptions support the same RBAC permissions as regular queries; Hasura Cloud includes managed subscription infrastructure without requiring self-managed WebSocket infrastructure |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — Hasura monitors API health (query execution latency, error rates, active subscriptions, database connection pool, cache hit rates) via the Hasura Cloud observability dashboard and OpenTelemetry/Prometheus integrations; Hasura 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 Hasura |
| 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 Hasura; Hasura provides GraphQL query analysis, slow query logs, and API performance reports but no plain-English explanation of WCAG violations or SEO improvements for the rendered front-end |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — Hasura does not audit or alert on WCAG compliance for applications built on its GraphQL API; government agencies, nonprofits, and educational institutions using Hasura for public-facing web applications face ADA Title II compliance requirements with an April 24, 2026 deadline; Next.js, React, and Vue applications querying Hasura's GraphQL API can introduce ARIA violations, color contrast failures, missing alt text on database-driven image content, keyboard navigation gaps, and inaccessible form components with each frontend deployment — Hasura's GraphQL API layer has no front-end quality gate; GraphQL query responses containing CMS content, product listings, or user-generated content may include HTML markup without proper heading hierarchy or alt text that Hasura will serve without any accessibility validation |
| Works on any platform | ✓ Yes — scans any URL on any front-end or platform | Hasura is a database API layer; it does not monitor or audit front-end applications built with non-Hasura data sources |
| 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 Hasura's GraphQL API |
| 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 Hasura as their API layer requires separate tools like Lighthouse or axe-core run against the live rendered frontend URL |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | Hasura Cloud provides a project dashboard for managing multiple Hasura projects, database connections, API endpoints, and usage metrics; there is no cross-application front-end health monitoring showing WCAG accessibility, SEO, and Core Web Vitals scores across multiple web applications |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Health monitoring not available — Hasura Cloud Free: 60 req/min, 100MB/month; Professional: $99/month; Enterprise: custom; self-hosted: free (Docker); no front-end quality monitoring included at any tier |

No — Hasura is a GraphQL engine with no built-in WCAG compliance checking. Hasura connects to databases and delivers JSON API responses but has no awareness of how client applications render those responses in the browser DOM. Common issues include ARIA violations in React components rendering GraphQL results, missing alt text on database-served images, inaccessible data tables from Hasura subscriptions, and keyboard navigation gaps in dynamically rendered content. PageGuard audits your live site and provides a WCAG 2.1 AA score with specific issues to fix.
Hasura’s GraphQL engine delivers fast, type-safe API responses, but front-end accessibility quality is entirely determined by the React, Next.js, or Vue application consuming Hasura’s API. Each frontend deployment can introduce WCAG violations without any check from Hasura. Government agencies, nonprofits, and universities face ADA Title II requirements with an April 24, 2026 deadline. Real-time subscriptions pushing live data updates can also introduce dynamic accessibility issues including focus management failures that static linting tools cannot detect. PageGuard provides continuous post-deployment accessibility monitoring with email alerts when scores drop.
No — they serve completely different purposes. Hasura is a GraphQL engine that provides instant, auto-generated GraphQL and REST APIs over existing databases with real-time subscriptions, RBAC, and event triggers. PageGuard is an external quality monitoring tool for the rendered front-end output of web applications — including those built on Hasura. Teams using Hasura as their API layer should add PageGuard to continuously verify WCAG compliance, Core Web Vitals, and SEO quality of their Hasura-powered frontend applications.
