Self-hosted, high-performance JSON Schema registry turning Git repositories of schemas into a searchable catalog.

PlatformWebunknown

One is a high-performance, self-hosted JSON Schema registry from Sourcemeta that turns existing Git repositories of schemas into a single, searchable, governed catalog for an organization, aiming to be its single source of truth for schemas. It is written in C++ and distributed under a proprietary license rather than a standard open-source one. It targets engineering organizations that maintain many JSON Schemas spread across multiple Git repositories and need central discoverability and governance.
