Hey Product Hunt! 👋 Leon here, the maker of SiteVertex. As a web developer and SEO enthusiast, I was constantly frustrated by how slow, bloated, and intrusive most SEO extensions have become. Today, almost every SEO tool requires you to create an account, hook up an API key, or wait for them to fetch data from a slow external server just to check basic on-page metrics. I wanted something instant. So, I built SiteVertex. SiteVertex is a blazing-fast, privacy-first Chrome extension that runs 100% locally in your browser. No API keys, no accounts, and absolutely no data leaving your machine. Here is what you get instantly with one click: ⚡️ Live Core Web Vitals: Real-time measurement of LCP, FCP, CLS, and live INP directly in the browser. 🧠 JS Rendering Comparison: Instantly compare Server-Side Rendered (SSR) HTML vs. Client-Side Rendered (CSR) DOM to catch JavaScript indexing issues. 🔍 Deep Schema.org Validation: Extract, read, and validate structured data without messy code inspection. 🌍 Local SERP Simulator: Check local Google rankings exactly as they appear in any specific city worldwide. 🔗 Canonical & Robots Checks: Catch misconfigurations before they destroy your rankings. We operate on a freemium model: The core on-page analysis is completely free forever. For power users and agencies, our Pro version unlocks the deep technical analysis tools (like JS rendering and the Local SERP simulator). I built this tool to scratch my own itch, but I want to make it the absolute best on-page SEO companion out there. I’d love to hear your honest feedback! What’s your biggest annoyance with your current SEO tools, and what feature would you love to see added to SiteVertex next? I'll be hanging out in the comments all day to answer your questions! 👇 P.S. To celebrate our launch, use code PRODUCTHUNT at checkout for 20% off the Pro Lifetime deal!"
