What is Marmot?

Marmot is an open-source data catalog for teams who want powerful data discovery without enterprise complexity. Catalog every data asset, enrich it with the context that matters and make it accessible to your team and your AI tools.

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.

Features

• Search everything: Find any data asset in seconds with full-text search plus structured queries, boolean logic and metadata filters.
• Interactive lineage: Trace data flows from source to destination and analyse impact before making changes.
• Metadata-first: Store rich metadata for any asset type, from tables and topics to APIs and dashboards.
• Team collaboration: Assign ownership, document business context and maintain shared glossaries.
• AI-ready: Expose certified context through MCP, the API and the UI.
