Discover any data asset
across your entire org in seconds
The open-source data catalog for modern teams. Search tables, topics, queues, buckets, APIs, and more - all in one place.
Search everything
Find exactly what you're looking for with a powerful query language that works across all your data assets.
Track lineage
Understand dependencies and assess impact before making changes. Built-in support for OpenLineage.
Deploy in under five minutes
Marmot runs as a single binary backed by PostgreSQL - the only dependency you need to start cataloging your data.
Follow the Quick Start guide
Rich metadata
Store comprehensive metadata for any asset type. From tables and topics to APIs and dashboards.
Less infrastructure, same power
Traditional data catalogs need an entire platform team. Marmot needs a database you probably already run.
Team collaboration
Assign ownership, document business context, and create glossaries. Keep your team aligned.
Connect to your data sources
Growing ecosystem of plugins
Don't see your data source? Open an issue to request a plugin.
Built to scale
Simple architecture doesn't mean limited. Marmot handles real workloads on modest infrastructure.
Populate your way
Use CLI, API, Terraform, or Pulumi to manage your data catalog as code
