Schema.biz vs WooCommerce Rich Snippets & Schema Markup

Schema.biz is a free browser toolkit for structured data markup, database schemas, and API specifications. Its markup tools generate, validate, and optimize JSON-LD, Microdata, and RDFa. A visual schema designer exports SQL for PostgreSQL, MySQL, SQLite, and SQL Server; database tools also diagram CREATE TABLE statements, compare schema versions, visualize queries, and offer templates. API tools validate JSON Schema, edit OpenAPI specifications, generate schemas and mock data, convert formats, and detect breaking changes. An AI Search Optimizer checks structured data readiness for ChatGPT Search, Perplexity, and Google AI Overviews. Pasted data is processed in browser JavaScript, and the maker says it is not sent to its servers. For URL-based markup checks, however, the server fetches the requested page for the browser to inspect. The free plan includes all tools without feature gates, limits, or signup. Persistent cross-device work and third-party URL crawling are not offered; an API Validator and Mock Server are marked as coming soon.

WooCommerce Rich Snippets & Schema Markup is a WordPress plugin that adds structured data to WooCommerce pages, so search results can show details such as product price and availability. The product page lists 13 schema types, including product, business, book, recipe, carousel, article, course and FAQ. Product schema can include name, price, description, SKU, availability, ratings and reviews. Business or organization schema supports details such as a name, logo, URL, hours, location, contact information and team members. The plugin can add breadcrumbs to product and service pages. Book fields include author, edition, format, publication date, publisher, ISBN and abridged status; recipe fields include author, cooking time, publication date, description, image, instructions and yield. Carousel schema applies at a general level. The free Community edition includes six months of Extendons support and future updates. Listed minimum versions are WooCommerce 2.6.0 and WordPress 4.6. Extendons says it was founded in 2017 to create extensions, plugins and themes, and lists an address in Islamabad, Pakistan. Its privacy policy was last updated September 9, 2021; Extendons says it collects order and website usage data and allows account holders to request deletion.
