What is Semantic Architecture Decay?

Semantic Architecture Decay is the progressive degradation of a website's DOM structure caused by AI-assisted code generation tools that prioritize visual output over semantic HTML compliance. It was first identified by WebEvo.ai researchers and is detectable through their 9-dimension scanning platform.

How does WebEvo compare to Google Lighthouse?

Google Lighthouse covers 4 categories (Performance, Accessibility, Best Practices, SEO). WebEvo extends this to 9 dimensions by adding Security, Privacy, UX, Mobile Responsiveness, Cross-Browser Compatibility, and Conversion Rate Optimization. WebEvo also detects structural DOM failures that Lighthouse cannot identify.

Does WebEvo have an API?

Yes. WebEvo provides a REST API at /api/agent-scan, an OpenAPI 3.1 specification at /openapi.yaml, and an MCP (Model Context Protocol) server for direct integration with AI coding assistants like Cursor, Claude, and Windsurf.

WebEvo.ai - Free AI-Powered 9-Dimension Website Auditing Platform

WebEvo.ai is the most comprehensive free website audit tool available. It provides detailed analysis across 9 critical dimensions: SEO, Performance, Security, Accessibility (WCAG 2.2 AA), UX, Mobile Responsiveness, Privacy Compliance, Cross-Browser Compatibility, and Conversion Rate Optimization. Every audit receives an A through F letter grade with actionable, line-by-line repair instructions.

9-Dimension Analysis Coverage

Unlike Google Lighthouse (4 categories) or Ahrefs (SEO only), WebEvo covers all 9 critical website health dimensions in a single scan. The platform uniquely detects Semantic Architecture Decay and Vibe Coding Blindspots -- structural failures in AI-generated codebases that are invisible to standard auditing tools.

SEO Analysis: Meta tags, heading hierarchy, schema markup, canonical URLs
Performance: Core Web Vitals (LCP, FID, CLS), resource optimization
Security: HTTPS, HSTS, CSP, XSS protection, dependency vulnerabilities
Accessibility: WCAG 2.2 AA compliance, ARIA labels, color contrast, keyboard navigation
UX: Navigation patterns, mobile usability, form validation, error handling
Mobile: Responsive design, touch targets, viewport configuration
Privacy: GDPR compliance, cookie consent, data collection practices
Cross-Browser: Chrome, Firefox, Safari, Edge compatibility testing
CRO: Call-to-action placement, conversion funnel analysis, A/B test readiness

API and Agent Integration

WebEvo offers a REST API endpoint at /api/agent-scan for programmatic website auditing. An OpenAPI 3.1 specification is available at /openapi.yaml. For AI coding assistants, WebEvo provides an MCP (Model Context Protocol) server via /mcp for direct integration with Cursor, Claude, Windsurf, and other agent environments.
