✓ Our Verdict

Solid choice for most workflows

Use Case

You need to build multi-step workflows that orchestrate scripts, APIs, and human approvals without managing infrastructure or writing boilerplate orchestration code.

SolutionWindmill transforms scripts (Python, TypeScript, Go, Bash, SQL) into executable workflows with auto-generated UIs, REST APIs, and scheduling. Compose steps with branching, loops, error handlers, and approval gates in a drag-and-drop builder.

SetupStart free on Windmill Cloud or self-host the open-source version on Kubernetes. For self-hosting, you'll need container orchestration and PostgreSQL. Enterprise features (SSO, audit logs, Git sync) are built-in, not add-ons.

Fast iteration—scripts become usable workflows in minutes. Execution history and real-time dashboards are solid. Horizontal scaling works via worker nodes. Quirk: error handling is per-step, so you need to design retry/fallback logic explicitly; silent failures are prevented by default.

Developer velocity and operational transparency drive the 82/100 score.

Use Case

You're building internal tools or dashboards but don't want to maintain separate frontend, backend, and orchestration layers.

SolutionWrite backend logic once in your language of choice; Windmill auto-generates production-ready web UIs with validation, embeddable apps (React/Vue/Svelte), and REST endpoints. One codebase powers scripts, UIs, agents, and scheduled tasks.

SetupMinimal—write a script with input parameters, Windmill generates the UI. For custom frontends, use the embedded app builder or REST API. No separate deployment pipeline needed.

UI generation is fast and handles basic validation. For complex custom UIs, you'll drop into React/Svelte. Performance is good for internal tools (not high-traffic public apps). RBAC and secrets management are enterprise-grade out of the box.

Reduces dev time and infrastructure overhead for internal tooling.

Use Case

You need to orchestrate AI agents with tool-calling, DAG execution, and sandboxed access to your scripts and data without building a custom orchestration layer.

SolutionWindmill's AI agent support includes tool-calling primitives, DAG orchestration, and direct access to your scripts as callable tools. Agents run in sandboxes with granular resource limits and audit logging.

SetupDefine scripts as tools, compose them into agent flows, integrate LLMs via API. Windmill handles sandboxing, resource isolation, and execution tracking. Self-hosting gives you full control over agent data.

Agent execution is reliable with detailed logs. Tool-calling works well for deterministic tasks. Expect to manage prompt engineering and LLM API costs separately. Scaling agents horizontally is straightforward via worker nodes.

Native AI support and sandboxing are differentiators for agent builders.

Limitation — minor

Limited pre-built connectors vs. low-code platforms

Windmill excels at custom code but has fewer pre-built connectors than n8n or Zapier. For CRM/ERP/marketing integrations, you'll write API calls directly in Python/TypeScript rather than drag-and-drop connectors. This is faster for developers but slower for non-technical users.

Caution

Self-hosting requires Kubernetes and operational overhead

While Windmill Cloud is managed, self-hosting demands Kubernetes expertise, PostgreSQL management, and ongoing maintenance. If your team lacks DevOps capacity, the operational burden can outweigh customization benefits. Start on Cloud to validate before self-hosting.
