Dagster is a data orchestrator that aims to empower organizations by building productive and trustworthy data platforms. The company's mission is rooted in a set of beliefs about how data pipelines and platforms should be built, which include thinking of data engineering as software engineering, embracing heterogeneity in data platforms, unifying them across the organization, adopting declarative approaches over imperative ones, and centering assets such as data assets. These beliefs have influenced Dagster's design principles, including code being king, embracing non-production environments, multi-tenancy from day one, and making choices that prioritize doing the right thing over ease in the short run. The company encourages users to adopt these principles by providing a tool that makes it easy to develop pipelines in code, declaratively, and link them into a unified whole.
