Editorial take
Why it stands out
Marquez should be framed as the reference-service layer around OpenLineage, not just another generic metadata project.
Loading
Tool profile
Open-source metadata service and web UI for storing, querying, and visualizing OpenLineage metadata across pipelines and datasets.
Lineage metadata service
Marquez is worth adding because it gives the OpenLineage ecosystem a concrete reference implementation teams can actually run. It is more than just an abstract standard companion. The official site positions it as the complete OpenLineage solution, with a metadata server, visual graph, and lineage API for understanding interdependencies across a data estate.
Its pricing posture is also clean. Marquez is open source and the GitHub repository is Apache 2.0 licensed. The official project site does not expose a first-party commercial pricing page, which means the practical cost is operational: hosting it, integrating it, and deciding whether it is the right service layer for an organization's lineage workflow.
