# MetaSnap

> A free, all-in-one SEO and meta tag toolkit for developers. Preview meta tags across every major platform, run deep SEO audits, generate favicons, OG images, JSON-LD schema, robots.txt and XML sitemaps, audit broken links, and inspect keyword density — all in your browser, with no signup or rate limits.

MetaSnap is a developer toolkit that helps you preview and optimise everything related to meta tags, SEO, and social sharing. It scrapes Open Graph, Twitter Card, and standard HTML meta tags from a URL, renders accurate previews across seven platforms, audits the page for SEO completeness, and provides a suite of generators (favicons, OG images, JSON-LD schema, robots.txt, sitemaps) plus auditors (broken links, keyword density). A free public REST API exposes the same functionality.
