SEO Inspector empowers developers, marketers, and SEO professionals to perform deep technical audits on any website, right from their iPhone. This app renders full webpages, including dynamic JavaScript content and Single Page Applications (SPAs), allowing you to inspect exactly what search engines and users see after the page fully loads.

Features: • View RAW HTML & Rendered DOM • Extract and preview meta tags, Open Graph and canonical elements • Verify robots.txt, sitemaps, and hreflang tags • See complete heading structure (H1–H6) • Detect redirects (301, 302, JavaScript-based) • Analyze JSON-LD structured data (Schemas) • Review FAQ markup and schema presence • Lightweight and privacy-respecting • Adapts automatically to your iPhone’s Light or Dark Mode for optimal readability. Whether you're debugging SEO implementations, auditing client websites, or validating how SPAs are rendered, SEO Inspector gives you everything you need in a clean and efficient interface.

API Debugger's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.
