ScanTheThings - Web Audit & Accessibility

Instant 1-click WCAG accessibility, SEO, performance, and quality audits on any tab. Works behind logins, firewalls, and local dev.

Instant 1-click web auditing directly in your active browser tab. Audit accessibility (WCAG 2.1 AA), SEO, broken links, images, security headers, and performance in under a second. Unlike remote crawlers that get blocked by Cloudflare, firewalls, or CAPTCHAs, ScanTheThings runs client-side inside your browser. This means you can audit: ✔ Pages behind passwords and login walls (staging, dashboards, admin portals) ✔ Local development environments (localhost:3000, Vite, Next.js, WordPress) ✔ Single Page Apps (React, Vue, Angular, Svelte) with dynamic DOMs ✔ Cloudflare/WAF-protected websites with zero 403 blocks ═══════════════════════════════════════════════ THE 10-ENGINE AUDIT SUITE ═══════════════════════════════════════════════ 1. WCAG 2.1 AA Accessibility: Powered by the industry-standard Axe-core engine to identify color contrast issues, missing aria-labels, form controls, and screen-reader violations. 2. Link Integrity & Tabnabbing: Detects broken hash links, empty anchors, and external links missing rel="noopener noreferrer". 3. Asset & Resource Integrity: Spots 404 failed images, scripts, stylesheets, and font requests. 4. Content Security Policy (CSP): Evaluates CSP header presence and unsafe directives (unsafe-inline / unsafe-eval). 5. Mixed Content & Security: Flags insecure HTTP resources, password inputs on unencrypted pages, and insecure form actions. 6. Core SEO & Structure: Audits title tags, meta descriptions, canonical URLs, heading hierarchy (H1-H6), and Open Graph tags. 7. Robots & Indexing: Checks meta robots tags, X-Robots-Tag headers, and search indexability flags. 8. Media & Layout Stability: Catches oversized images (>1MB), missing alt text, and images without width/height attributes that cause layout shift (CLS). 9. Typo & Spell Checker: Flags misspelled words and repeated words in rendered page content. 10. Performance & Network: Measures TTFB, DOM Interactive, DOM Complete, resource count, and total page weight. ═══════════════════════════════════════════════ KEY FEATURES ═══════════════════════════════════════════════ • Blazing Fast: Audits standard web pages in 200–500 milliseconds. • Code Remediation Hints: Every finding includes the exact CSS selector, HTML code snippet, and actionable fix instructions. • Custom Ignore Rules: Suppress false positives or third-party embeds (like Google Analytics, Intercom, or cookie banners) by CSS selector, URL pattern, or issue type with 1 click. • Seamless Dashboard Sync: Connect your free ScanTheThings account to store audit history, track scores over time, and collaborate with your engineering team. • 1-Click Export: Copy findings instantly formatted as clean GitHub Markdown or export to CSV. ═══════════════════════════════════════════════ PRIVACY FIRST ═══════════════════════════════════════════════ • Zero tracking, analytics, or behavioral telemetry inside the extension. • Audits run 100% locally in your browser tab. • Only activates when you click the extension icon.
