A friendly stack for data-intensive apps

Modern data and ML apps require a thick stack of infrastructure from integrations to data warehouses and scalable compute layers to workflow orchestration and versioning. Metaflow provides one human-friendly API to the full stack which allows data scientists to focus on modeling and business logic, and engineers on providing stable infrastructure.
