In their own words
Dagster
Dagster is a data-aware orchestrator for building, running and monitoring data pipelines and assets. It models assets and dependencies to show lineage across a data platform, while supporting partitions, incremental runs, declarative workflows and fault-tolerant orchestration. An integrated catalog combines data discovery, lineage, workflows and operational metadata. Quality features include code-embedded validation, automated testing, freshness checks and observability tools. The integration directory lists Airbyte, Anthropic, Apache Airflow, AWS services and Azure Data Lake Storage. Dagster+ hybrid deployment keeps compute in a customer’s infrastructure while Dagster manages the control plane. The core framework is open source on GitHub. Platforms listed are API, Linux, self-hosted and web; deployment is hybrid. A 30-day trial is listed. Solo costs $10 a month plus usage charges, and Starter costs $100 a month plus usage charges. Dagster’s website says it is now part of Prefect.
Dagu
Dagu is a self-hosted workflow engine for defining DAG workflows in YAML and managing runs, logs and retries through a built-in web interface. It runs as a single binary locally or across distributed workers, without an external database or message broker. Workflows can run shell scripts, Docker containers, SSH commands, SQL queries, HTTP requests, chat completion steps and Agent Harness steps. Scheduling supports cron timezones, catchup windows, overlap and retry policies, zombie detection, lifecycle handlers and notifications. Built-in actions cover HTTP, mail, SSH, SFTP, Git, S3, Redis, LLM, browser, computer, SQL, PostgreSQL, SQLite and DuckDB. Dagu also supports MCP connections from clients including Claude Code, Codex, Cursor, VS Code, Gemini CLI, OpenCode, Zed and Cline. The project is open source under GNU GPL v3.0. Its free Community plan includes unlimited servers and workers, with up to two API keys. Team is $50 a month and Pro is $150 a month; both add SSO, role-based access, audit logging, incident routing and standard support.
