Spec score 7.1 #17 of 26 in Schema Registry Software

What it is

Sourcemeta One is a self-hosted JSON Schema micro-service that turns Git repositories into searchable catalogs with governance features. Teams can organize schemas by team, department, domain, or vendor, and see lint-based quality scores. Schemas and registry configuration remain in Git, so changes can follow existing review workflows; the service has no database, write path, or stateful persistence. Its web explorer is optional, and headless deployments can use the HTTP API. It supports JSON Schema Draft 3, Draft 4, Draft 6, Draft 7, 2019-09, and 2020-12, alongside format validation, custom meta-schemas, annotation collection, and bundling. Community is a free self-hosted edition with a subset of functionality under Business Source License 1.1; releases transition to AGPL-3.0-or-later after four years. Enterprise requires a commercial license for production, with annual or perpetual terms and pricing on request. Docker images are provided for x64 and arm64, and Docker is the only officially supported running method. Commercial licenses include expert support and training; managed hosting is available upon request.
