OpenMetadata

OpenMetadata is an open-source context layer that unifies technical context, business semantics, and organizational memory into a single graph, solving the problem of fragmented metadata and lack of shared understanding for AI agents and humans. It targets data teams, developers, and executives in enterprises and mid-market companies, offering a schema-first, API-first architecture with 130+ connectors. Positioned as the leading open-source solution, it provides a simple deployment with only four system components and includes features like data discovery, lineage, observability, quality, collaboration, and governance.
