Deploy and Host Dagu on Railway

About Hosting

Dagu is a self-contained workflow engine written in Go with an embedded TypeScript/React Web UI. It uses file-based storage (no external database required) and runs as a single binary via dagu start-all, which launches the web server, scheduler, and coordinator together. The Docker image is ghcr.io/dagu-org/dagu:latest from GHCR.

Why Deploy

• Zero-Ops: Single binary, under 128MB memory footprint, no PostgreSQL/Redis/message broker needed
• Full-Power Orchestration: 19+ built-in executors including Docker, SSH, HTTP, SQL, S3, and more
• AI-Native: Built-in LLM agent for creating, editing, and debugging workflows from natural language
• Web UI: Rich dashboard with DAG visualization, log viewer, and workflow management
• Air-Gapped Ready: Runs in isolated environments without external dependencies
• Persistent Storage: Railway volume ensures DAG definitions and run history survive redeployments

Common Use Cases

• Scheduling and orchestrating ETL/data pipelines with YAML-defined DAGs
• Automating DevOps tasks like deployments, backups, and monitoring checks
• Running periodic batch jobs (report generation, data sync, cleanup scripts)
• Orchestrating multi-step CI/CD workflows with conditional logic and retries
• Managing distributed task execution across multiple workers
