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.
