What each one is
Dagster
Dagster models pipelines around the data they produce rather than the tasks they run — which makes lineage and testing far easier than in Airflow.
- Asset-centric model with built-in lineage
- Local development that actually works
- Strong typing and testing story
CVAT
CVAT is the professional annotation tool for video and images — bounding boxes, polygons, skeletons, with interpolation across frames.
- Interpolation makes video annotation bearable
- Automatic annotation with your own models
- Used by large annotation teams
Key differences
Dagster is data orchestration, while CVAT is video & image annotation. Their licenses differ (Apache-2.0 vs MIT), which matters if you ship a commercial product. In short, Dagster fits teams who want their pipelines testable and their lineage visible, and CVAT fits computer vision datasets, especially video.
Which should you choose?
Choose Dagster for teams who want their pipelines testable and their lineage visible. Choose CVAT for computer vision datasets, especially video.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
Frequently asked questions
