 Dagu 
Dagu is a local-first workflow engine for operations and internal automation. It is open source and self-hostable: a single binary with a built-in Web UI, no external database or message broker, running on Linux, macOS, and Windows. Define DAGs in a declarative YAML format. It natively supports shell commands, Docker containers, Kubernetes Jobs, remote commands via SSH, and more through Dagu Actions.
Dagu turns existing scripts and runbooks into production workflows with scheduling, retries, human tasks, and run history. It runs where your data and credentials live: on-prem, air-gapped, edge, or cloud, and scales from a single node to a fleet of workers.
**Highlights:**
- Single binary installation.
- Self-contained: no external DBMS or message broker required.
- Runs on Linux, macOS, and Windows.
- Declarative YAML format for defining DAGs.
- Run existing shell commands, Docker containers, Kubernetes Jobs, and remote commands over SSH without modifications.
- Compose reusable Sub-DAGs and run work in parallel with concurrency controls.
- Schedule workflows with cron syntax, timezones, overlap policies, and catch-up windows.
- Keep logs, run history, retries, notifications, and webhook triggers in one place.
- Built-in MCP server for inspecting workflows and runs, maintaining Wiki pages, applying changes, and controlling runs.
- Optional monitoring in Dagu Console: every server's runs and trends in one place, and an email when a workflow fails or a server stops reporting. Opt-in, outbound HTTPS only, metadata only.

## Why Dagu?
Orchestration is not your main work. You have scripts and containers that already work. You want a schedule, retries, dependencies, and a place to see logs. The usual options each have a cost:
- **cron** runs commands, but gives you no dependencies, no retries, no history.
- **Airflow** orchestrates, but you operate a platform for it (scheduler, metadata database, workers, a Python environment), and your jobs get rewritten as `@dag`/`@task` framework code.
- **Temporal** gives durable execution, but your business logic moves into its SDK and programming model.
You wanted to schedule some jobs. Now you operate a second system, and the orchestrator lives inside the code it was supposed to serve.
Dagu treats workflow structure as configuration, not code. Order, dependencies, retries, schedules, and human tasks go in one YAML file next to your scripts; the engine that runs them is a single process:
 [code] 
Your scripts never import the orchestrator. Delete the YAML and they run exactly as before. Keep it, and every run gets a dependency graph, retries, per-step logs, history, and a Web UI.
## Performance
Dagu stores state in local fil
