Dagster — Developer Tools

What is Dagster?

Dagster is a modern data orchestrator that treats data pipelines as software assets, not just DAGs. It helps data teams build, observe, and deliver reliable data workflows — from simple ETL to complex AI pipelines. The open-source core is free, and Dagster+ adds cloud services, role-based access, and AI-powered operational insights for scaling teams.

What problem does it solve?

Dagster solves the chaos of managing data pipelines by providing asset-based lineage, built-in testing, and full observability. Instead of debugging broken pipelines after the fact, teams catch issues early with automatic dependency tracking, type checks, and a unified UI that shows run history, logs, and error stack traces. For production platforms, Dagster helps reduce pipeline execution time, eliminate manual tasks, and improve data freshness.

Who is it for?

Best for data engineers and platform teams building production-grade ETL/ELT pipelines, especially those migrating from Airflow. It is less suited for simple ad-hoc scripting without pipeline complexity. Use cases include scheduling dbt models, event-driven triggers via sensors, and managing data assets across S3, GCS, and Azure Blob storage.

• Asset-based pipelines — define data assets, not just tasks, for clear lineage and dependencies
• Lineage tracking — auto-generated dependency graph of all assets, end to end
• Testing framework — unit tests, integration tests, and type checks before deployment
• Scheduling & sensors — cron schedules and event-driven triggers (e.g. file drops)
• dbt integration — run dbt models as Dagster assets with zero downtime
• Cloud storage — read/write from S3, GCS, Azure Blob storage
• UI dashboard — run history, logs, and error debugging in one view
