Schema Graph Inspector

Overview

Visualize JSON-LD schema as an interactive graph in a full-page viewer.

Schema Graph Inspector helps you understand JSON-LD structured data by turning it into a clear, static visual graph. Instead of scanning raw schema markup, you can instantly see entities, properties, and relationships laid out in a readable structure. This makes it easier to validate schema implementations, spot structural issues, and understand how entities connect on a page. The visualization is static and deterministic, so the layout stays stable. No animations, no force-based movement, and no visual noise. What you see is the schema. Features - Extracts JSON-LD (application/ld+json) from the current page - Visualizes entities and relationships as a static graph - Shows schema structure and nesting at a glance - Toggle between visual graph and raw JSON-LD - Lightweight and fast, runs entirely in the browser Use cases - SEO and structured data audits - Schema debugging and validation - Understanding complex entity relationships - Technical reviews and documentation Made with ❤️ by search minds
