The Problem We've all been there. You run a Lighthouse audit or check PageSpeed Insights. It gives you a red score and a vague list of complaints:
"Eliminate render-blocking resources"
"Ensure text remains visible during webfont load"
"Serve static assets with an efficient cache policy"
Great. Thanks. But how do I fix it? Usually, that means 2 hours of Googling and messing with config files.
The Solution I spent the last few months building Refactor.tools. I wanted to build the "ultimate" website audit tool that doesn't just complain, but actually helps you fix the code.
What makes it different? Unlike standard validators, I built this with a "Fixer First" mentality using a modern stack (Next.js, Supabase, Puppeteer):
Real User Data (CrUX): It doesn't just run a lab test; it pulls real-world Chrome User Experience data (LCP, INP, CLS) so you know how actual users feel.
GEO (Generative Engine Optimization): This is new. It checks if your site is ready for AI Search (ChatGPT, Perplexity), including llms.txt detection and AI readability scoring.
The AI Fixer: This is the killer feature. If it finds a missing meta tag, a bad CSP header, or broken JSON-LD, it generates the copy-paste code to solve it.
💀 The "Roast Mode" (Proceed with Caution) I got a little bored during development, so I added a "Roast My Site" tab. It uses vision-capable AI to look at your landing page and critique your design, UX, and copy. It does not hold back. It’s hilarious, but honestly... it’s usually right.
The Tech Stack For those interested in how it's built:
Frontend: Next.js on Vercel.
Backend: Supabase (Auth/DB) + Google Cloud Run for the heavy lifting.
Analysis: Headless Puppeteer for DOM analysis + CrUX API.
Security: We use Vercel Edge Middleware to inject dynamic nonces for strict CSP compliance (a pain to build, but worth it for security).
🚀 I need your help to break it It’s almost ready for the public, but I need honest feedback to make it bulletproof.
I am looking for Founding Members. If you try it out and send me an honest email about your experience (what broke, what confused you), I’ll give you the PRO Plan for free (1 year).
