In their own words
Dagu
Dagu is a self-hosted workflow engine for defining DAG workflows in YAML and managing runs, logs and retries through a built-in web interface. It runs as a single binary locally or across distributed workers, without an external database or message broker. Workflows can run shell scripts, Docker containers, SSH commands, SQL queries, HTTP requests, chat completion steps and Agent Harness steps. Scheduling supports cron timezones, catchup windows, overlap and retry policies, zombie detection, lifecycle handlers and notifications. Built-in actions cover HTTP, mail, SSH, SFTP, Git, S3, Redis, LLM, browser, computer, SQL, PostgreSQL, SQLite and DuckDB. Dagu also supports MCP connections from clients including Claude Code, Codex, Cursor, VS Code, Gemini CLI, OpenCode, Zed and Cline. The project is open source under GNU GPL v3.0. Its free Community plan includes unlimited servers and workers, with up to two API keys. Team is $50 a month and Pro is $150 a month; both add SSO, role-based access, audit logging, incident routing and standard support.
Windmill
Windmill is an open-source workflow engine and developer platform for building endpoints, workflows and user interfaces. It is aimed at teams making internal software across engineering, data, sales, support and marketing. Scripts can be written in TypeScript, Python, Go, PHP, Bash, C#, SQL, Rust, Ruby and R, among other languages. Windmill combines a script editor, low-code flow builder, and low-code, React or Svelte app builders. Scripts and flows can be triggered by webhooks, schedules, HTTP routes, queues or an open API. Its Hub lists more than 200 resource types, including GitHub, Slack, AWS, BigQuery and PostgreSQL; users can also define custom resource types with schemas. Local development through the CLI and Git sync support version control and deployment workflows. Self-hosting is supported. The free and open-source plan is free and includes three workspaces, 50 users, 10 GiB of workspace object storage and 100 guest app users per 30 days. Enterprise is $120 a month and includes a month-long trial. Enterprise features include granular permissions, RBAC, secret management, OAuth, SSO and audit logs.
