Schema.dev
Chicago, Illinois, United States
What it is
Schema.dev provides tools to create, test, and deploy structured data for webpages. Its guided, point-and-click builder generates formatted JSON-LD and advertises support for more than 40 schema types, with a stated goal of covering every Schema type supported by Google. Users can copy the output into pages or use it with the deployer, and can transform text or supply custom field content. A separate tester validates structured data supported by Schema.org through a user interface, with an optional API endpoint. The tester is described as supporting testing at scale in both pre-production and production environments. Its API checks implementations for errors, warnings, and recommended elements. The builder is also available as a Chrome extension. The tester UI and builder extension are free; larger-scale testing can use an optional API. Deployment through a tag manager or DNS is described, but the deployer is labeled coming soon. Cloudflare-managed DNS integration is also marked as coming soon. Schema.dev is a product of seoClarity Labs.
