Dagster is a modern open-source data orchestration platform that centers on data assets to help teams build, schedule, and monitor data and AI pipelines.
Primarily aimed at data engineers, data platform engineers, full-stack data scientists, ML engineers, data analysts, and DevOps/platform engineers.
Airflow centers on task scheduling and is suitable for general workflows; Dagster centers on data assets, emphasizing data lineage, observability, developer experience, and asset governance.
Dagster offers a fully functional open-source free version. It also provides professional/enterprise editions named Dagster Cloud or Dagster+, which include team collaboration, enhanced deployment, and enterprise support.
Primarily Python programming knowledge, since its core development is declarative in Python. Familiarity with data engineering or related data processing concepts is helpful.
Supports local development environments, Docker containers, Kubernetes clusters, and serverless architectures for deployment and execution.
As an open-source platform, Dagster provides resource abstractions to manage external connections. Specific security and compliance practices depend on the user’s deployment configuration and infrastructure.
Install dagster and dagit via pip, use the scaffolding command to initialize a project, then build pipelines by defining assets, ops, and jobs, and manage and monitor them through the Dagit UI.
Dagster is primarily designed for batch processing and data-asset orchestration. For high-throughput, low-latency real-time streaming, it typically needs to be used in conjunction with dedicated stream processing systems (e.g., Apache Flink).

Dust is an enterprise-grade, customizable AI agent platform that lets teams quickly build, deploy, and manage AI agents that connect internal knowledge bases and tools using no-code or low-code approaches. It is designed to boost collaboration and scalable knowledge management.
Inngest AI Workflows is an event-driven, persistent execution platform that simplifies the orchestration of AI and backend workflows. By abstracting away the complexity of the underlying infrastructure, it lets developers focus on business logic and build efficient, reliable, and scalable background tasks and complex workflows.
