Frequently Asked Questions
Is Marquez a direct alternative to Atlan?
Not exactly. Marquez is a focused open-source lineage service, while Atlan is a full data workspace covering catalog, governance, collaboration, and AI. Marquez handles one piece of the puzzle — lineage collection and visualization — whereas Atlan addresses the broader metadata management lifecycle. Organizations sometimes use Marquez alongside a catalog platform rather than as a standalone replacement.
Can I use Marquez and Atlan together?
Yes. Since Marquez is the reference implementation of OpenLineage, teams can use it to collect lineage from Airflow, Spark, and dbt pipelines, then feed that metadata into a broader catalog like Atlan for discovery and governance. This hybrid approach gives you open-standard lineage collection with enterprise catalog features on top.
What does Atlan cost compared to Marquez?
Marquez is completely free under the Apache-2.0 license, though you bear the cost of self-hosting and maintaining the infrastructure. Atlan offers a free tier for one user, followed by Pro, Team, and Enterprise tiers with increasing feature sets and custom pricing at the enterprise level. External reviewers note that Atlan list prices can be steep for smaller organizations, but negotiated volume discounts make it more economical at scale.
Which tool is better for data lineage specifically?
For pure lineage collection and visualization, Marquez is purpose-built. It is the reference implementation of the OpenLineage standard and integrates natively with Airflow, Spark, Flink, dbt, and Dagster. Atlan provides lineage as part of a broader platform with 80+ connectors and a visual lineage graph, but it does not natively implement the OpenLineage standard. Teams that prioritize open-standard lineage interoperability often lean toward Marquez.
How mature is Marquez compared to Atlan?
Marquez has 2,170 GitHub stars and its latest release is version 0.50.0. It is actively maintained with code pushed as recently as April 2026. Atlan is a venture-backed company with 201-500 employees, recognized as a Leader in the 2025 Gartner Magic Quadrant for Metadata Management and the 2026 Gartner Magic Quadrant for Data & Analytics Governance. Both are actively developed, but Atlan has broader commercial maturity and enterprise adoption.
