jsonld.com is a JSON-LD structured data tool site founded by Patrick Coombe, co-founder of Elite Strategies. It aims to provide SEO practitioners and webmasters with validated, real-world JSON-LD code examples and convenient free generators, helping users quickly deploy Schema markup on web pages to qualify for rich results in search engines and improve content extraction by large language models (LLMs).
Features and Use Cases: The tool offers two core functions: first, a library of real-world code examples covering 50+ high-frequency Schema types such as Local Business, Product, and FAQ; second, free JSON-LD generators for 17 types, with practical features such as real-time validation, one-click export to Google Rich Results Test, and persistent form state. The site also provides small helper tools such as latitude/longitude conversion.
Language and Ecosystem Support: It mainly focuses on front-end JSON-LD markup, but usefully includes practical code snippets for WooCommerce (PHP) and Shopify, making it easy for e-commerce developers to reuse them directly. The site itself is statically built with Astro. From an ecosystem perspective, it not only follows the Google Search ecosystem closely, but also looks ahead by emphasizing the value of structured data for parsing by LLM crawlers such as ChatGPT and Claude.
Open Source and Pricing: The tool is a closed-source web application and is completely free to use. It does not provide an API or SDK and does not support self-hosting, so it cannot meet the needs of programmatic bulk generation.
Documentation Quality: The site itself effectively serves as documentation, presenting real code in a minimalist terminal-style interface. Its blog content is also high quality—for example, its in-depth coverage of Google deprecating FAQ rich results points out that structured data still has major value for LLM extraction, showing strong industry insight.
As a completely free tool, it offers excellent value. Its strengths include examples sourced from real high-authority websites, no-registration access, and close tracking of SEO trends. Its drawbacks are that the generator covers a limited number of types (only 17) and lacks an API, making it unsuitable for development teams that need to automate integration into CI/CD workflows.
It is a great fit for independent site owners, SEO practitioners, and front-end developers who need to quickly generate structured data manually. It is less suitable for large SaaS platforms that require automated bulk markup generation.
The site is statically generated with Astro and has no complex external dependencies. Its accessibility from China is unknown, but direct access is likely to face relatively few restrictions. Since it is completely free, there are no payment barriers. For alternatives, consider Merkle Schema Markup Generator or Google’s official Structured Data Markup Helper.
