About Dagu

Dagu runs workflows described in YAML files, calling your existing scripts, SSH commands and containers in the order you define. It keeps the workflow definitions separate from the code they run, and it includes a web interface for running and watching jobs.

It ships as a single binary and needs no database, so it runs on limited hardware. It is aimed at teams that need scheduled jobs and pipelines as an alternative to cron or Airflow without running a large orchestration stack.

Strengths

  • Single binary with no database to set up
  • Declarative YAML workflows over existing scripts and commands
  • Runs on modest hardware
  • Web interface for running and monitoring jobs

Limitations

  • Workflows must be written in YAML
  • You host and maintain the server yourself
