Score Breakdown
⚙ Agent Friendliness
🔒 Security
Open metadata/data catalog platform. JWT + OAuth2. Data lineage and schema metadata may reveal architecture. RBAC for data asset access. Self-hosted for sensitive data environments.
⚡ Reliability
Best When
An organization has data spread across many warehouses, databases, and BI tools and needs a single discovery and governance layer with lineage and quality monitoring.
Avoid When
The data estate is small and simple, or the team lacks capacity to operate a Docker/Kubernetes deployment.
Use Cases
- • Building a centralized data catalog for discovering tables, dashboards, pipelines, and topics
- • Tracking end-to-end column-level data lineage across a modern data stack
- • Running no-code data quality tests and monitoring freshness, volume, and schema drift
- • Enforcing data governance policies with ownership assignment, tagging, and auto-classification
Not For
- • Small teams without a significant multi-source data landscape
- • Real-time event streaming platforms (it catalogs, not processes data)
- • Teams needing a fully managed SaaS with zero self-hosting
Interface
Authentication
Supports SSO, OAuth, and JWT-based authentication. Role-based access control built in.
Pricing
Apache 2.0 open-source. Enterprise commercial offerings may exist; not detailed in README.
