Declarative TOML
No complex coding required. Define your data pipelines using readable, version-controlled TOML files.
Engine Agnostic
Transformations are decoupled from execution. Run the same flow on SQL, Pandas, or PySpark.
Built-In Quality
First-class data contracts and quality checks integrated directly into your pipelines.
Code Generation
Export your declarative flows into robust SQL, DBT models, or Airflow DAGs automatically.
