In their own words
Baseline Labs Schema Generator
Baseline Labs Schema Generator reads a live webpage, identifies its type, and produces JSON-LD structured data. It supports more than 20 schema.org types, including Article, Product, FAQPage, HowTo, LocalBusiness, and SoftwareApplication. The generated script tag can be placed in the page head; the markup is static and needs no server changes or extra libraries. Each generation captures the page as it appears at that time. A separate Rolling Schema feature re-crawls pages and regenerates markup on a schedule, as often as every 30 minutes. The generator page currently reports that the service is temporarily offline and that submitted pages are queued. An API can generate JSON-LD for a URL; API requests use an X-API-Key header, and access is included on Power and above. Plans range from Free to Ultimate, with paid plans at 79.00 EUR, 249.00 EUR, and 749.00 EUR or more per month. The company was founded in 2025 and is based in Galway, Ireland.
Schema.biz
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.
