In their own words
StructuredValidator
StructuredValidator is a free web tool for checking structured markup, with validation focused on JSON-LD. Paste JSON-LD or HTML to see results as you type. It detects Microdata and RDFa in pasted HTML, but validates JSON-LD only. Checks cover JSON syntax, contexts, types, property names, value formats, @id references, and required or recommended properties for supported rich-result features. The URL tool fetches public HTTP or HTTPS pages, extracts JSON-LD from server HTML, and validates it in the browser without rendering JavaScript. Fetches allow four redirects, eight seconds, 2 MB per page, and 12 requests per minute per visitor. A comparison view places two schema implementations side by side to show differences, missing properties, and coverage. Rich-result preview and API access are available. Validation history and preferences stay in browser storage, and the service says it does not retain validation data on its servers. Optional AI suggestions send markup and errors to an AI provider under that provider’s retention policy.
