Dagu

Dagu is a workflow orchestration tool that runs as a single binary without requiring an external database. Developers use it to define task dependencies as directed acyclic graphs through declarative YAML, then schedule and monitor execution through a web interface. It supports scripts, SSH commands, containers, and other execution methods, making it suitable for teams building automated workflows and data pipelines. The tool emphasizes simplicity and low resource requirements, functioning as an alternative to traditional job schedulers and orchestration platforms.

Dagu is developed by dagucloud and released under the GPL 3.0 license. The project is written in Go and designed for self-hosting. It includes features such as retry logic, human approval tasks, logging, and integrations with various services and platforms. The tool aims to keep workflow definitions separate from business logic while operating on minimal hardware resources.
