What Sourcemeta One is
Sourcemeta One is a self-hosted JSON Schema micro-service for turning Git repositories of schemas into searchable catalogs with governance. It uses Git as the source of truth, without a database, write path or stateful persistence, so schema and registry changes can move through a team's existing review process. Catalogs can be organized by team, department, domain or vendor, and schemas receive lint-based quality scores. The optional web explorer can be left out for headless deployments that use the HTTP API. Supported drafts are Draft 3, Draft 4, Draft 6, Draft 7, 2019-09 and 2020-12, with format validation, custom meta-schemas, annotation collection and bundling. Community is a free self-hosted edition with a subset of functionality; its Business Source License 1.1 releases transition to AGPL-3.0-or-later after four years. Enterprise requires a commercial license for production, with pricing on request and annual or perpetual licensing. Deployment is officially supported through Docker images for x64 and arm64; individual OS binaries are not provided.
