Our Schema Markup Generator & Validator engine is open source under HiMat Technology. Star the project, inspect the source, report issues, or contribute on GitHub.
Unlike remote SEO platforms that store product catalogs, internal addresses, or unpublished schema drafts on external servers, HiMat's Schema Markup Generator executes entirely inside browser memory. Zero tracking, zero network requests.
Schema markup (JSON-LD) is structured data added to web pages to help search engines (Google, Bing) and AI search engines (ChatGPT Search, Perplexity) understand your content entities, products, organizations, FAQs, and events, enabling rich snippets and direct citations.
No. The HiMat Schema Markup Generator operates 100% locally in your web browser. Neither your entity details, FAQ entries, nor product prices leave your local machine.
Copy the generated `<script type="application/ld+json">` block and paste it inside the `<head>` or `<body>` of your HTML document, or pass the JSON-LD object to your Next.js/React framework's script tag.
Our tool supports Organization, Article, FAQPage, Product, LocalBusiness, WebApplication, HowTo, SoftwareApplication, Event, and Person schemas with full property customization.
Yes, 100% free forever without registration, rate limits, or advertisements.
