What is n8n?

n8n is a workflow-automation platform that lets technical teams connect apps, automate processes and build AI agents through a visual canvas — with the option to drop into real code whenever they need to. Open source with 200k+ GitHub stars, it's the tool for people who want the speed of no-code but refuse to be boxed in by it.

What n8n is

n8n lets you build automations by dragging nodes onto a canvas and wiring them together, while also allowing JavaScript or Python code nodes for anything the visual blocks can't express. It connects 500+ apps out of the box, supports building multi-agent AI workflows with full transparency, and runs either as a hosted cloud service or fully self-hosted — including air-gapped, on-premises deployments.

Who it's for

n8n is aimed at technical teams across an organization: IT ops automating onboarding, security teams enriching incident tickets, DevOps integrating APIs, and sales teams generating customer insights — plus enterprises needing governance and control. Its visual-plus-code approach makes it ideal for developers and technically-minded operators who find pure no-code tools too limiting.

What it offers

  • Drag-and-drop canvas with JavaScript/Python code nodes
  • Real-time input/output inspection and single-step replay
  • 500+ pre-built integration nodes and 10,000+ templates
  • Multi-agent AI workflows with RAG support
  • Flexible model integration (cloud or offline) with human-in-the-loop
  • Self-hosting, including air-gapped on-premises deployment
  • SSO/SAML, RBAC, encrypted secrets and version control
  • Audit logs, SIEM integration and MCP support

Visual speed, code freedom

n8n's defining strength is that it doesn't force a choice between no-code and code. You build fast on the visual canvas, but when a task needs custom logic, you drop in a code node and do exactly what you want — as one user put it, "I can move fast and never feel boxed in." That hybrid is why developers prefer it over purely visual tools that hit a wall the moment your needs get slightly unusual.

AI agents you can actually see into

As n8n has moved into AI, it's kept a strong emphasis on observability. You can build multi-agent workflows with RAG, but crucially inspect every prompt, response and decision, add human-in-the-loop approvals, and set guardrails — so AI automation stays traceable and controllable rather than a black box. For teams wary of unpredictable AI acting on real systems, that full execution transparency is a major differentiator.

Run it your way, keep control

Because n8n is open source and self-hostable, teams can run it entirely on their own infrastructure — even air-gapped — keeping sensitive data and automations fully in their control. Combined with enterprise features like SSO, RBAC, encrypted secret management, audit logs and SIEM integration, that makes it viable for security-conscious organizations that can't send their workflows and data through a third-party cloud.

Start fast with templates and testing

n8n lowers the barrier to building despite its power. Over 10,000 workflow templates give you proven starting points for common automations, so you're rarely building from scratch, and its 500+ integration nodes cover most apps you'd want to connect. When you do build, real-time input/output inspection, single-step replay and data mocking make testing fast — you can see exactly what each step produces and debug without running the whole flow repeatedly. That combination of ready templates and strong debugging tools means teams get working automations quickly and iterate on them with confidence.

Why choose n8n

For technical teams that want powerful automation and AI workflows without being constrained, n8n is a standout choice. Its visual-plus-code building, 500+ integrations, transparent AI agents, and self-hostable, enterprise-ready deployment make it a practical way to automate processes and build agents on your own terms — fast when you want it, fully customizable when you need it, and under your control when that matters.

What is Windmill?

Windmill is an open-source developer platform that turns scripts into production-grade workflows, scheduled jobs, APIs and internal tools — combining the flexibility of code with the convenience of a low-code platform. It's aimed at developers and technical teams who want to automate processes and build internal applications without the limitations of pure no-code tools or the overhead of building everything from scratch. You write logic in real languages (Python, TypeScript, Go, Bash, SQL and more), and Windmill handles turning that into scalable, reliable automation.

The platform's versatility is its strength. From individual scripts, Windmill lets you build multi-step workflows with a visual flow editor, schedule jobs with cron, expose logic as APIs and webhooks, and create internal app UIs and admin tools on top of your code. This means a single platform can replace a patchwork of automation tools, internal tooling frameworks and job schedulers, all while keeping your business logic in maintainable, version-controllable code rather than locked inside a proprietary visual builder. It handles execution, dependencies, secrets, permissions and observability so you don't have to.

Being open source, Windmill can be self-hosted for full control, privacy and cost efficiency — appealing strongly to teams that want to own their automation infrastructure — with a cloud option available too. It's designed for performance and scale, and supports collaboration so teams can build and share scripts, flows and apps. This makes it a powerful fit for engineering, data and operations teams that need to automate workflows, run scheduled jobs, and build internal tools quickly while retaining the power and maintainability of code. For developers who find no-code automation too limiting but don't want to build and operate their own automation stack from zero, Windmill offers a flexible, open and genuinely powerful platform that bridges the gap.
