Datadef is a web application that helps data engineers and architects visualize data lineage, define table relationships, and generate documentation automatically.
I’ve spent years as a data consultant and constantly saw teams struggle with documenting lineage and metadata. Most relied on Excel sheets, static diagrams, or tribal knowledge, which made onboarding, governance, and compliance unnecessarily painful. Datadef exists to fix this problem — giving data engineers and governance teams a simple, interactive way to visualize their data and generate documentation without wasting hours.
Datadef is a web app that helps data engineers and architects visualize lineage, define table relationships, and auto-generate documentation. Datadef gives you a dedicated canvas to explore your data models and metadata.
It’s designed not just for productivity, but also for data governance: making lineage transparent, metadata shareable, and documentation reliable for compliance and onboarding. Think of it as the clarity layer between your data pipelines and the people who need to trust them.
