Ever found yourself juggling multiple tabs to check your site's meta tags, Open Graph previews, robots.txt, and sitemap? I got tired of it too. So I built Site Metadata Explorer — a free tool that analyzes everything in a single scan.
Try it now: site-metadata.sivaramp.com
The Problem
As developers, we constantly need to verify:
- Are my meta tags correct?
- Will my Open Graph preview look good on Twitter/LinkedIn?
- Is my robots.txt blocking the wrong pages?
- Does my sitemap include all important URLs?
- Is my JSON-LD structured data valid?
Most tools only check one thing at a time. I wanted everything in one place.
What It Does
Enter a URL and get instant analysis of:
1. Basic Meta Tags
Title, description, keywords, viewport, charset — with character count validation.
2. Open Graph & Twitter Cards
See exactly how your site will appear when shared on social media.
3. Icons & Favicons
All your apple-touch-icons, favicons, and PWA icons in one view.
4. robots.txt Analysis
Parsed directives, sitemap references, and crawl rules at a glance.
5. Sitemap Discovery
Automatic sitemap detection with URL counts and structure overview.
6. JSON-LD Structured Data
View and validate your schema.org markup.
7. Web Manifest
PWA manifest.json analysis for app icons, theme colors, and display modes.
8. Security.txt & llms.txt
Yes, we check those too. Because details matter.
The Killer Feature: LLM-Ready Exports
Here's where it gets interesting. You can export all metadata as:
- JSON — for programmatic use
- Markdown — perfectly formatted for AI workflows
Open in AI with One Click
Export directly to Claude, ChatGPT, or Gemini. Perfect for:
- "Analyze this site's SEO and suggest improvements"
- "Compare this metadata with competitor sites"
- "Generate a technical SEO audit report"
File Size Overview
At a glance, see the size of every file fetched:
This helps identify bloated sitemaps, missing files, or oversized responses.
Built for Mobile Too
Fully responsive design that works great on any device. Check your site's metadata on the go.
Tech Stack
For the curious developers:
- Next.js 15 — React framework with App Router
- Tailwind CSS — Utility-first styling
- shadcn/ui — Beautiful, accessible components
- Cheerio — Server-side HTML parsing
The entire app is open source: GitHub
What's Next?
Some features I'm considering:
- [ ] Historical comparisons (track changes over time)
- [ ] Bulk URL analysis
- [ ] API access for CI/CD integration
- [ ] Browser extension

One More Thing...
Need PWA icons for your project? I also built pwa-icons — generate all platform-specific icons from a single image.
npx pwa-icons generate logo.png
It's what I used to generate all the icons for Site Metadata Explorer itself.
