marmot

Marmot is an open-source data catalog designed for powerful data discovery across an organization's entire data stack, including databases, APIs, message queues, and data pipelines. It offers a simple, fast deployment as a single binary with an intuitive UI, making it easy to catalog assets and track lineage without complex enterprise overhead.

marmot sits in the Vision / Multimodal category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Powerful Search for Data Assets. A representative use case is Discover and search all types of data assets across the organization.
