Dagster
San Francisco, California, United States
What it is
Dagster is a data-aware orchestrator for building, running, and monitoring pipelines and data assets. It models assets and dependencies so teams can see lineage across a data platform. Workflows support partitions, incremental runs, declarative definitions, event triggers, automatic retries, and fault-tolerant orchestration. An integrated catalog brings together discovery, lineage, workflows, and operational metadata. Validation in code, automated testing, freshness checks, and observability tools support data quality. Integrations include Airbyte, Anthropic, Apache Airflow, AWS services, and Azure Data Lake Storage. Dagster+ hybrid deployment keeps compute in your infrastructure while Dagster manages the control plane, and the core framework is open source. Solo costs $10 a month; Starter costs $100 a month, with additional credit and serverless-minute charges. A 30-day trial is listed.
