Sourcemeta One
What Sourcemeta One is
Sourcemeta One is a self-hosted JSON Schema micro-service that turns schema Git repositories into searchable catalogs with governance features. Teams can group schemas by team, department, domain, or vendor, and review lint-based quality scores. Schema and registry configuration stay in Git, so changes can pass through an organization’s existing review workflow. The optional web explorer can be omitted for headless deployments that use the HTTP API. Supported JSON Schema versions run from Draft 3 through 2020-12, with format validation, custom meta-schemas, annotation collection, and bundling. Documented integrations include Sourcemeta JSON Schema CLI, Deno HTTPS imports, OpenAPI schema references, and Visual Studio Code autocomplete. The service has no database or stateful persistence; Git is its source of truth. It is distributed as Docker images for x64 and arm64, and Docker is the only officially supported running method. Community is free with a subset of functionality; Enterprise requires a commercial license for production and pricing is available on request.
