Faultry
Faultry is an innovative website audit tool designed to put your site through a rigorous "car crash test" before launch or for ongoing maintenance. It goes beyond traditional performance checks to audit critical aspects like mobile responsiveness, social media card previews, security headers, and AI discoverability, ensuring your website is robust and ready for the modern web.
This SaaS is ideal for web developers, site owners, and marketing professionals who need to ensure their online presence is flawless, secure, and easily discoverable by both users and AI crawlers.
Key Features
Comprehensive 6-Point Audit: Deep checks on security, mobile viewport, social cards, AI visibility, console errors, and performance (Core Web Vitals).
Stack-Specific Fixes: Generates copy-paste code snippets tailored for popular frameworks like Next.js, React, SvelteKit, Nuxt, Vue, and Express.
Real-World Mobile Rendering: Verifies actual mobile viewport behavior, including horizontal overflow, touch targets, and font zoom risks, not just a responsive design checkbox.
Social Card Previews: Shows exactly how your links will appear when shared on platforms like Twitter, LinkedIn, Discord, and Slack.
AI Discoverability Checks: Audits llms.txt, robots.txt, sitemap accessibility, and detects cloaking to ensure AI crawlers can find and understand your content.
Advanced Security Header Analysis: Goes beyond mere presence to check the effectiveness of HSTS, CSP, X-Frame-Options, DNSSEC, CAA, and Mixed Content.
Use Cases
Faultry is an indispensable tool for ensuring a smooth website launch. Developers can leverage its deep checks to identify and rectify critical issues such as security vulnerabilities, mobile display glitches, or broken social sharing previews before their site goes live, preventing potential user frustration and reputational damage.
For established websites, Faultry serves as a powerful ongoing optimization and maintenance solution. Site owners can regularly audit their platforms to maintain peak performance, bolster security, and enhance AI visibility, ensuring their content remains discoverable and provides an optimal user experience. It's also excellent for quickly troubleshooting common problems like console errors, performance bottlenecks, or inaccurate social media link previews, providing actionable insights and direct fixes.
