Schema.dev vs Schema Markup Info

Schema.dev provides tools to build and test structured data for webpages, and describes a deployment tool as coming soon. Its guided point-and-click builder generates formatted JSON-LD, advertises more than 40 schema types, and lets users transform text or enter custom field content. The output can be copied into pages or used with the Schema deployer. A separate tester validates structured data supported by Schema.org through a user interface or optional API endpoint. The tester is described as supporting tests at scale in both pre-production and production environments; API checks can report errors, warnings, and recommended elements. The Schema Builder is also offered as a Chrome extension. Schema.dev lists free plans for the tester UI and builder extension, with an optional API for larger-scale testing. Deployment is described as using an existing tag manager or DNS, but the deployer is labeled coming soon; DNS-level integration for Cloudflare-managed DNS is also coming soon. The site links to a help center with a knowledge base and community contact option. Schema.dev is a product of seoClarity Labs. Its about page says seoClarity has been helping SEO professionals since 2008. The listed platforms are API, extension, and web.
