Lakeflow Designer is a visual, no-code, AI-native experience for data preparation and analytics. Built directly in Azure Databricks, it lets users prepare and explore data through a drag-and-drop canvas and natural language. The workflows you build, called visual data preps, are backed by production-ready code and fully governed by Unity Catalog, so your work moves smoothly from prototype to production, with no need to reverse-engineer or rebuild.
