The record

Purpose: Sourcemeta One is a high-performance, self-hosted JSON Schema micro-service that turns Git repositories of schemas into searchable catalogs with governance capabilities.
GitOps governance: Schemas and registry configuration live in Git, so changes and deployments pass through the team's existing review workflow.
Catalog and quality: Schemas can be grouped by team, department, domain, or vendor, and the product gives schemas quality scores based on linting.
Web explorer and API: The web explorer is optional, and Sourcemeta One can run headless for API-only deployments using its HTTP API.
Schema support: The product supports JSON Schema Draft 3, Draft 4, Draft 6, Draft 7, 2019-09, and 2020-12, with format validation, custom meta-schemas, annotation collection, and bundling.
Integrations: Documented integrations include Sourcemeta JSON Schema CLI, Deno HTTPS imports, OpenAPI schema references, and improved Visual Studio Code autocomplete.
Enterprise capabilities: Enterprise adds features including custom lint rules, authentication and access control, dialect upgrades, MCP support, JSON-LD/RDF support, and the JSON Schema Standard Library.
Security: Enterprise container images include Cosign/Sigstore signatures, a signed SPDX SBOM, SLSA Build Level 3 provenance, and an OpenSSL FIPS provider for FIPS-ready cryptography.
Architecture: Sourcemeta One has no database, write path, or stateful persistence; its source of truth is a Git repository.
Deployment: The service is distributed as Docker images for x64 and arm64, and Docker is the only officially supported running method; individual operating-system binaries are not provided.
Support: Commercial licenses include expert commercial support and training, and Sourcemeta says managed hosting is available upon request.
Intended users: The product is presented for organizations seeking a schema catalog and API governance, and for tooling companies embedding schema infrastructure through its HTTP API.
