Marmot is an open-source data catalog built for teams that want powerful data discovery and lineage without the weight of enterprise tools like Atlan, Alation, or DataHub. It ships as a single Go binary — no Kubernetes, no Spark cluster, no multi-service deployment. Boot it up, connect your data sources, and start searching in minutes. The core feature set covers full-text and structured metadata search, interactive data lineage graphs, schema versioning, and ownership tracking. The standout differentiator is native MCP integration: Marmot exposes an MCP server so AI coding tools like Claude, Cursor, and Windsurf can query your data catalog directly — asking questions like "what tables contain PII?" or "show me the lineage for this dbt model" without leaving your IDE. Built with Go on the backend and Svelte on the frontend, Marmot is at v0.8.3 with 531 GitHub stars and an active Discord community. It launched on Product Hunt today. For data teams at startups and mid-sized companies that are currently using a spreadsheet or Notion doc as their "data catalog," Marmot is a no-brainer migration target.
Reviewer scorecard
“Behavioral cohorts and the query engine are powerful. Best for understanding complex user journeys.”
“Single binary, MIT license, MCP server built in — this is how OSS infrastructure tools should ship. I had it running against our Postgres and dbt setup in 20 minutes. The lineage graph actually works, which is more than I can say for most 'enterprise' catalogs I've paid for.”
“PostHog offers similar features with open source and better pricing. Hard to justify Amplitude's enterprise pricing.”
“v0.8.3 suggests this is still pre-production for anything serious. Data catalog adoption historically requires political buy-in across data, engineering, and analytics teams — a single binary doesn't solve the human problem. Also, connectors for enterprise sources (Snowflake, Databricks, Redshift) aren't all there yet.”
“The CDP + analytics + experimentation convergence is the right direction. Amplitude is well-positioned.”
“MCP-native data catalogs are the beginning of AI agents being able to reason about your entire data estate. Marmot's architecture — lightweight, single binary, open protocol — is the right foundation for the next wave of agentic data tools. This could become the Prometheus of data catalogs.”
“For smaller data teams drowning in undocumented tables and mystery pipelines, Marmot is a genuine quality-of-life upgrade. The UI is clean and modern — rare for OSS data tools — and the search actually surfaces context you'd otherwise need to Slack a senior engineer for.”
