Marmot is an open-source data catalog designed for teams who want powerful data discovery without enterprise complexity. Built with a focus on simplicity and speed, Marmot helps you catalog assets across your entire data stack - from databases and APIs to message queues and data pipelines.

Unlike traditional catalogs that require extensive infrastructure and configuration, Marmot ships as a single binary with an intuitive UI, making it easy to deploy and start cataloging in minutes.

Built for Modern Data Teams

  • Deploy in Minutes: Single binary, Docker, or Kubernetes - no complex setup required
  • Powerful Search: Powerful query language with full-text, metadata, and boolean operators
  • Track Lineage: Interactive dependency graphs to understand data flows and impact
  • Flexible Integrations: CLI, REST API, Terraform, and Pulumi - catalog assets your way
  • Lightweight: PostgreSQL-backed with minimal resource requirements

Find any data asset across your entire organisation in seconds. Combine full-text search with structured queries using metadata filters, boolean logic, and comparison operators.
