Dagster is a modern, data-aware orchestration platform that enables organizations to build, scale, and observe data and AI pipelines with confidence. Founded in 2018, Dagster Labs provides both an open-source platform and commercial cloud offering (Dagster+) for unified data asset orchestration, including lineage tracking, metadata management, data quality monitoring, and data cataloging. The platform emphasizes asset-first modeling where data pipelines are declared around desired data assets rather than task-oriented steps.
