SEO & developer tools,forged from bugs.
Every tool here started as a production bug that ruined one of my weeks. I fixed it, then turned the fix into something you can run on your own site. Paste a URL, get answers — that's the whole deal.
A canonical tag silently pointed to localhost in production. Google de-indexed the page for weeks.
<link rel="canonical" href="http://localhost:3000/" />Canonical URL Checker
Paste any URL and see whether your canonical tag, og:url, and JSON-LD schema URLs agree — and whether any of them leaked localhost, the wrong protocol, or a stray port.
Two <title> tags fighting across a template. Google kept picking the wrong one.
<title>Real Page</title> … <title>Default</title>Meta Tag Auditor
Audit your title, description, Open Graph, and Twitter Card tags — catch duplicates, missing og:image, and bad lengths — and see your real social-share preview.
