n8n vs Windmill in 2026: Visual Open-Source vs Code-First Automation
Quick Answer: n8n and Windmill are both self-hostable open-source automation platforms but optimize for different audiences. As of May 2026, n8n provides a visual node editor with 420+ integrations and fair-code licensing, while Windmill offers polyglot scripting (TypeScript, Python, Go, Bash, SQL) with auto-generated UIs and an MIT-licensed core.
n8n vs Windmill: Key Differences
n8n and Windmill are both open-source automation platforms that can be self-hosted, but they target different user profiles. n8n is a visual workflow builder designed for operations teams, with 400+ pre-built integrations and a node-based canvas. Windmill is a code-first platform designed for developers, supporting TypeScript, Python, Go, Bash, SQL, and GraphQL scripts with auto-generated UIs and faster execution for compute-intensive tasks.
The core distinction: n8n prioritizes visual building and integration breadth for teams that want to automate without writing code. Windmill prioritizes developer experience and execution performance for teams that prefer code-defined workflows.
Feature Comparison (as of March 2026)
| Feature | n8n | Windmill |
|---|---|---|
| License | Sustainable Use License (fair-code) | AGPLv3 |
| Integrations | 400+ pre-built | REST API + custom scripts |
| Builder | Visual node canvas | Code editor + visual flow |
| Languages | JavaScript, Python (in code nodes) | TypeScript, Python, Go, Bash, SQL, GraphQL |
| Cloud pricing | From $20/mo | From $10/mo |
| Self-hosted | Free (Docker, K8s) | Free (Docker, K8s) |
| Auto-generated UI | No | Yes (typed inputs become forms) |
| GitHub stars | 40,000+ | 12,000+ |
| Execution speed | Standard (Node.js) | Optimized (Rust runtime) |
When to Choose n8n
n8n is the stronger choice for teams that need a visual workflow builder with a large library of pre-built integrations. The node-based canvas allows operations teams, marketers, and non-technical users to build automations by connecting pre-configured modules. The 400+ integration library covers CRM, email, databases, cloud services, and communication tools.
n8n's community is significantly larger (40,000+ GitHub stars, active Discord, extensive documentation). The template library, community nodes, and third-party tutorials make troubleshooting and learning faster. For teams that want a production-ready platform with community support and visual building, n8n is the more mature choice.
When to Choose Windmill
Windmill is the stronger choice for engineering teams that prefer code-defined workflows. Scripts in TypeScript, Python, Go, Bash, SQL, or GraphQL are first-class citizens -- typed inputs automatically generate user-facing forms, and outputs are logged and versioned. The Rust-based runtime delivers faster execution for CPU-intensive data transformations compared to n8n's Node.js runtime.
Windmill's auto-generated UI feature is distinctive: a TypeScript function with typed parameters automatically becomes a form-based internal tool that non-technical team members can run. This bridges the gap between developer-built logic and operational use without requiring a separate internal tool builder.
The AGPLv3 license is more permissive than n8n's Sustainable Use License for certain use cases, though the AGPL requirement to share source code for network-accessible deployments may matter for some organizations.
Editor's Note: We deployed both on identical VPSs for a developer-heavy client. n8n's visual builder was preferred by their ops team for CRM sync workflows. Windmill won for data pipeline tasks where the engineering team wrote TypeScript scripts with typed inputs -- execution was roughly 3x faster than n8n for CPU-intensive transformations. They ended up running both.
Bottom Line
n8n is the better choice for teams that need visual workflow building, broad pre-built integrations, and a mature community. Windmill is the better choice for developer teams that prefer code-first automation with auto-generated UIs and faster execution. Both can be self-hosted for free; the decision depends on whether the primary users are operations teams (n8n) or developers (Windmill).

Best Automation Platforms for AI Orchestration 2026
This ranking answers one question: how many real business applications can an AI agent act on out of the box? It evaluates nine platforms as of August 2026 on the reach they give an agent, not on the workflow logic they can express. That boundary is deliberate, because two neighbouring pages on this site answer different questions. Best Process Orchestration Platforms 2026 scores multi-step process control, error handling and state management. Best AI Agent Platforms 2026 scores building and hosting the agent itself. This page scores the layer between them: the connective tissue that lets an agent already built elsewhere reach the applications a business actually runs on. A platform that leads one of those pages can place low here, and two of them do. Scores derive from application and action catalogue counts, the exposure model each platform uses to publish those catalogues to an agent, setup effort, failure handling and cost per agent action. Every figure was retrieved from a vendor-owned surface on 11 August 2026 unless an earlier date is stated against it.
Best Durable Workflow Engines for Production in 2026
A ranked list of the best durable workflow engines for production deployments in 2026. Durable workflow engines persist execution state to a database so that long-running workflows survive process restarts, deployments, and infrastructure failures. The ranking covers Temporal, Prefect, Apache Airflow, Camunda, Windmill, and n8n. Tools were evaluated on production reliability, developer experience, scalability, open-source health, and documentation quality. The shortlist intentionally mixes code-first engines (Temporal, Prefect, Airflow) with hybrid visual platforms (Camunda, Windmill, n8n) to reflect how production teams actually choose workflow engines in 2026.

Keystroke vs n8n in 2026: Agent-Built TypeScript vs the Visual Canvas
Keystroke, launched in July 2026 by Y Combinator W24 company Sprint Labs, is a code-first automation platform where AI coding agents write workflows as TypeScript in the user's repository. n8n, founded in 2019, is the most widely deployed source-available visual workflow platform, with 200,000+ users and a $2.5 billion valuation.
