What is n8n?

n8n is an open-source workflow automation platform particularly well-suited for AI workflows in enterprise environments. The name stands for "nodemation" (Node + Automation) — a visual workflow builder that enables creating complex automations without deep programming knowledge.

Open Source vs. Cloud

n8n offers two operating models:

Practical tip: For companies with strict data privacy requirements, self-hosting is the clear choice. You retain full control over all data and can run n8n within your existing infrastructure.

Comparison with Other Platforms

n8n vs. Zapier

• Zapier is purely cloud-based, easier to start, but more expensive at high volume
• n8n offers self-hosting, more flexibility for complex workflows, and native code nodes
• Zapier: ~2,000 integrations | n8n: ~400+ integrations + custom nodes

n8n vs. Make (Integromat)

• Make has a more visual interface and is cheaper than Zapier
• n8n offers more control over data flows and better error-handling options
• n8n has native AI nodes, Make relies on HTTP requests

n8n vs. Custom Code

• Custom code gives maximum flexibility but requires developers and maintenance
• n8n reduces development time by 60–80% for typical integration scenarios
• Ideal: n8n for the workflow, custom code only for specific logic within code nodes

When to Use n8n for AI Workflows?

n8n is particularly strong for AI workflows because:

1. Native AI nodes: Direct integration with OpenAI, Anthropic, Ollama, and other LLM providers
2. Visual debugging: Every step in the workflow is inspectable — ideal for prompt iteration
3. Hybrid approach: Combine no-code nodes with JavaScript/Python code nodes
4. Webhook triggers: Real-time processing of incoming requests (Slack, email, API calls)
5. Self-hosting: Sensitive company data never leaves your infrastructure

Practical tip: n8n is excellent as the "glue" between your AI models and existing systems. Instead of building custom API integrations, connect your tools visually.
