Modern DAG-based workflow scheduler with a web UI for managing cron jobs and task pipelines.
What you can build with Dagu
Dagu is a powerful open-source workflow scheduler that replaces traditional cron jobs with directed acyclic graph (DAG) pipelines managed through a clean web interface. Define workflows in simple YAML files with steps that can run shell commands, Docker containers, HTTP requests, SQL queries, and more — all with dependency chains, retries, and conditional logic built in.
Self-hosting Dagu on your own VPS gives you a single-binary scheduler with no database dependencies. File-based storage keeps things simple while the web UI provides real-time execution monitoring, log viewing, and manual trigger controls. This deployment includes built-in authentication and persistent storage for workflow definitions and execution history.
Key features of Dagu
DAG workflow editor
Define task dependencies as directed acyclic graphs in YAML with parallel execution, conditional branching, and retry logic.
Built-in step types
Run shell commands, Docker containers, HTTP requests, SQL queries, SSH commands, and S3 operations as native step types.
Real-time monitoring
Watch workflow execution progress in real-time through the web UI with step-level status, logs, and timing information.
Cron scheduling
Schedule workflows with cron expressions and manage all scheduled jobs from a single dashboard.
AI agent integration
Run AI coding agents like Claude Code, Codex, and Copilot as workflow steps with built-in harness support.
No database required
File-based storage means zero external dependencies — just a single binary with persistent volume for state and logs.

Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
