how to use

How to Use Dagster

Getting started with Dagster involves defining data assets and pipelines using Python, then deploying and monitoring them through the Dagit UI or programmatically via its API. The platform emphasizes a declarative approach to data orchestration.

  • 1Install Dagster: Begin by installing the dagster and dagster-webserver Python packages using pip.
  • 2Define Assets: Create Python functions decorated with @asset to define data assets and their dependencies.
  • 3Build a Job: Group related assets into a Job to define a logical unit of work.
  • 4Launch Dagit UI: Run dagster dev in your project directory to launch the Dagit UI for local development and monitoring.
  • 5Schedule Runs: Configure schedules or sensors to automatically trigger pipeline executions based on time or external events.
  • 6Deploy to Production: Deploy Dagster code locations to a production environment, such as Kubernetes, using Helm charts or Dagster+.

pricing

Dagster Pricing & Plans

Dagster operates on a freemium model, offering a free tier for individual use and open-source projects, alongside a commercial offering, Dagster+, for enhanced features and enterprise-grade support. The pricing model for Dagster+ shifted effective May 1, 2026, from fixed credits to a base fee plus a per-credit usage charge.

  • Free Tier: Available for individual users and open-source projects, providing core Dagster functionalities.
  • Dagster+ Solo Plan: Priced at $10/month plus $0.040 per credit (effective May 1, 2026).
  • Dagster+ Starter Plan: Priced at $100/month plus $0.035 per credit (effective May 1, 2026).
  • Dagster+ Enterprise Plan: Custom pricing, requiring direct contact with sales for tailored solutions and advanced features.

Pros

  • +Asset-centric approach enhances reliability and transparency in data orchestration, tracking metadata of tables and supporting re-runs and partitioned data.
  • +Robust observability and monitoring capabilities through the Dagit UI, offering real-time insights into pipeline performance and data asset health.
  • +Python-native development experience allows for defining modular, testable, and maintainable pipelines as decorated Python functions.
  • +Strong testing capabilities, facilitating unit and integration testing with comprehensive mock support.
  • +Integrated data lineage and governance features for compliance and auditing.
  • +Active development with frequent releases and continuous enhancements to features and integrations.

Cons

  • −The learning curve can be steep for new users unfamiliar with its asset-centric paradigm and Pythonic API.
  • −Recent pricing model changes (effective May 1, 2026) for Dagster+ may result in increased costs for certain usage patterns.
  • −While integrations are extensive, some users may require custom development for niche data sources or tools not natively supported.
  • −The Dagit UI, while powerful, can become complex with a very large number of assets or highly intricate dependencies.

Dagster vs Competitors

Dagster competes in the data orchestration landscape with several established and emerging platforms, each offering distinct approaches to workflow management. Its primary differentiation lies in its asset-centric model and integrated observability.

1
Apache AirflowOn Stork

It is a widely adopted, community-driven platform for programmatically authoring, scheduling, and monitoring workflows as Directed Acyclic Graphs (DAGs).

Airflow is more task-centric, requiring more manual effort to define data assets and their lineage compared to Dagster's native asset model. Its UI and observability features are generally less integrated and require more custom setup for data asset health.

2
PrefectOn Stork

Prefect focuses on building robust data pipelines with features like automatic retries, caching, and dynamic mapping, emphasizing workflow resilience.

Prefect offers a modern Pythonic API and better local development experience, but its asset-centric view and integrated observability are not as deeply embedded or comprehensive as Dagster's native asset model.

3
MageOn Stork

Mage provides a notebook-based development experience for building, running, and managing data pipelines, integrating well with modern data stacks and AI/ML workflows.

Mage offers a highly interactive notebook-first approach which can be great for data scientists, but its asset-centric metadata and integrated observability are not as mature or comprehensive as Dagster's dedicated asset catalog and Dagit UI.

4
LuigiOn Stork

Luigi helps build complex pipelines of batch jobs, managing dependencies and providing a user interface to visualize the workflow.

Luigi is a more lightweight and less opinionated framework compared to Dagster, offering basic dependency management and visualization but lacking Dagster's advanced asset-centric features, integrated observability, and rich metadata management.
