Test your website before your customers do.
AI writes your code 10x faster—but ships hidden bugs 10x faster too. ScanFix autonomously audits technical errors, Core Web Vitals, SEO leaks, and accessibility violations, then generates targeted prompts for Cursor & Claude Code to fix them and verifies the patch.

No vague homework. ScanFix gives your AI assistant the exact code prompt needed to achieve 100% health.
Overall Health Score
+14 pts gained in latest verification/pricing@fix Issue: Missing OpenGraph image and viewport meta tag on /pricing
Files: app/pricing/page.tsx, app/layout.tsx
Instructions:
1. Export complete metadata object containing openGraph { images: ['/og-pricing.png'] }
2. Ensure viewport is configured with width=device-width, initialScale=1
3. Validate deterministic SEO score targets 100/100AI writes code 10x faster. It also ships bugs 10x faster.
When anyone can build a full-stack SaaS in an afternoon using Cursor, Lovable, v0, or Bolt, your competitive edge isn't writing code—it's shipping software that actually works flawlessly.
Silent Regressions
When you prompt Cursor or Claude Code to "Redesign the pricing page", the LLM generates beautiful components—but quietly drops canonical tags, breaks OpenGraph metadata, and creates unclickable buttons on mobile.
Lighthouse Gives Warnings, Not Fixes
Traditional tools like Google Lighthouse print walls of confusing metrics like "Reduce main-thread work by 3.8s" and leave you to figure it out. They never tell your AI coding agent what file to edit or what patch to apply.
The Unverified Fix Illusion
Your AI assistant says "Fixed!". But did the patch actually work in production? ScanFix re-crawls your live environment, re-measures Core Web Vitals, and mathematically proves the bug is dead before your users notice.
SCAN → DETECT → FIX → VERIFY
Standard audit tools stop at complaints. ScanFix closes the loop by testing whether your AI-generated patches actually resolved the bug in production.
SCAN
Autonomous CrawlerAccepts any public URL. Secure headless browser inspects DOM structure, status codes, broken links, Core Web Vitals, and SSL headers with zero local RAM impact.
DETECT
Deterministic Rules100+ precision QA rules categorize issues by severity (Critical, High, Medium, Low). Calculates 100% reproducible category scores with zero LLM hallucinations.
FIX
Targeted AI PromptsGenerates actionable, structured prompts tailored specifically for Cursor, Claude Code, Antigravity, and Windsurf with exact file paths and code snippets.
VERIFY
The Mathematical DeltaRe-tests the live production site, fingerprints previously detected bugs, and proves whether your patch fixed the issue or if a regression was introduced.
Six Specialized QA Engines. Zero Blind Spots.
Most tools only test one thing—either just SEO or just Lighthouse. ScanFix audits your entire digital product across all six critical commercial dimensions in one pass.
Technical QA & Integrity
Crawls every route to discover broken links, dead assets, unhandled JavaScript console exceptions, and server-side errors before users hit them.
Audits Included:
- Broken internal & external link discovery (404/500 detection)
- Uncaught browser runtime exceptions & console errors
- Dead image / script / font asset references
- Mixed content (HTTP assets on HTTPS pages) warning
Performance & Core Web Vitals
Directly measures real Core Web Vitals (LCP, CLS, TBT, FCP, Speed Index) using official Google PageSpeed thresholds with resilient lab emulation.
Audits Included:
- Largest Contentful Paint (LCP < 2.5s threshold)
- Cumulative Layout Shift (CLS < 0.1 visual stability)
- Total Blocking Time (TBT main thread responsiveness)
- First Contentful Paint & Speed Index load timelines
Programmatic SEO & Social Cards
Ensures search engines can index your site cleanly and that shared links render eye-catching OpenGraph & Twitter preview cards.
Audits Included:
- Title length, uniqueness & missing meta description audits
- Canonical tag verification to prevent duplicate content penalties
- OpenGraph & Twitter Card image dimension validation
- robots.txt & XML sitemap discovery and parse checks
Defensive Security Configuration
Verifies your application uses enterprise-grade defensive HTTP headers to guard against clickjacking, XSS, and credential interception.
Audits Included:
- HSTS (Strict-Transport-Security) preload eligibility
- Content-Security-Policy (CSP) & X-Frame-Options clickjacking guard
- Cookie security flags (HttpOnly, Secure, SameSite)
- SSL certificate validity and HTTPS enforcement
WCAG 2.1 AA Accessibility
Automated checks aligned with WCAG 2.1 AA standards, ensuring your application is navigable by screen readers and compliant with accessibility laws.
Audits Included:
- Color contrast ratios on buttons, text, and form inputs
- Missing image alt attributes & descriptive label checks
- ARIA landmarks, roles, and keyboard navigation tab-index
- Form field association and error announcements
Mobile UX & Responsive Signals
Audits your mobile viewport behavior to ensure buttons are easily clickable, text is readable without zooming, and layouts do not horizontally overflow.
Audits Included:
- Tap target sizing (minimum 48x48px touch boundary check)
- Horizontal scroll & viewport overflow detection
- Legible font sizing across mobile breakpoint viewports
- Sticky CTA & navigation accessibility on small screens
