Turn Jira Data Into Strategic Clarity

Hey everyone, I'm Charlie - I built Marmot because data catalogs solve a simple problem: what data do we have and where does it live? But most catalogs will then ask you to run Elasticsearch, Kafka and a graph database just to find out. Data catalogs shouldn't need an entire platform team to run them.
Now your AI agents need to answer these same questions - without valid context, they hallucinate. Marmot gives them a single source of truth to query.

Marmot is a single binary and a Postgres database, deployable in minutes. It currently has:

25+ plugins (and growing) including - dbt, Kafka, S3, Trino, Iceberg, PostgreSQL.
Full data lineage across your business
Built-in MCP server to give LLMs context around your data
100% free and open-source.

I’m curious how easy it is for me to deploy and start using quickly without needing a dedicated data governance team. A quick-start guide or demo would really help me evaluate this faster.

I’ve been thinking a lot about how teams can bridge the gap between data and AI and this feels like a step in that direction. For me, the biggest challenge is not just finding data but trusting it.
