Overview
Dagster is a data orchestration platform built for productivity. Software-defined assets, type checking, and built-in testing for data pipelines.
Pros
- Apache 2.0 license
- Software-defined assets model
- Built-in testing framework
- Type system for data

Verdict
Dagster rethinks data orchestration around software-defined assets rather than task graphs. Instead of defining a DAG of tasks, you define the assets (tables, models, reports) and Dagster figures out the execution plan. The built-in testing, type system, and modern UI make it the most developer-friendly orchestration platform. For new data teams or teams willing to migrate from Airflow, Dagster provides a more productive development experience.
