Best for Teams needing a single pipeline that serves both real-time streaming and scheduled warehouse loads. Teams wanting an open-source ELT platform they can self-host for data control, or run as managed cloud, with a broad long-tail connector catalog. Data teams who want a fully managed, low-maintenance ELT pipeline into a cloud warehouse without operating infrastructure. Data engineers who want a version-controlled, code-first ELT framework rather than a GUI-driven tool. Teams wanting ingestion, transformation orchestration and reverse ETL bundled in one consumption-billed platform.
