n8n is an open-source workflow automation platform that connects apps, APIs, and AI models through a visual node-based builder, available as a self-hosted or cloud service.
n8n is an open-source workflow automation platform that connects apps, APIs, and AI models through a visual node-based builder, with an option to self-host for full control over your data. It uses a graph-based canvas where each “node” represents an app, a data transformation, or an AI call, and connections between nodes define how data flows. With more than 400 native integrations and the ability to call any API via HTTP nodes, n8n handles automations from simple two-step notifications to multi-step AI pipelines.
How does n8n work?
n8n works by connecting trigger nodes (the events that start a workflow) to action nodes (the tasks that execute), with optional AI, logic, and data transformation nodes in between. A typical workflow starts with a trigger — a new form submission, a scheduled time, or a webhook from an external app. Data then passes through nodes that transform it, call AI models, update databases, or send messages.
According to n8n’s 2024 platform documentation, the tool supports more than 400 native integrations and handles more than 1.5 billion workflow executions per month across cloud and self-hosted installations.
For AI-powered workflows, n8n includes native nodes for Anthropic Claude, OpenAI, and Hugging Face, allowing businesses to add an AI decision or generation step directly into any automation without custom code.
Why do small businesses use n8n?
Small businesses choose n8n when they need automation that goes beyond simple trigger-action rules, especially for AI-assisted workflows, sensitive data handling, or complex branching logic. Three factors drive adoption:
- Self-hosting keeps client and financial data on your own server, satisfying data residency requirements common in legal, healthcare, and financial services
- JavaScript nodes allow custom data transformations that no-code tools cannot handle
- No per-task pricing on self-hosted plans removes the cost ceiling that limits Zapier and Make at higher automation volumes
According to Gartner’s 2024 review of workflow automation platforms, self-hosted automation tools reduce total cost of ownership by 40–60% for organizations running more than 10,000 automations per month, compared to per-task cloud pricing models.
What is the difference between n8n, Zapier, and Make?
| n8n | Zapier | Make | |
|---|---|---|---|
| Self-hosting | Yes (free) | No | No |
| AI nodes | Native (Claude, GPT, Hugging Face) | Basic (OpenAI only) | Available |
| Custom code | Yes (JavaScript) | No | Limited |
| Pricing model | Free self-hosted; cloud per active workflow | Per task | Per operation |
| Complexity ceiling | High | Low to moderate | Moderate to high |
| Best for | AI workflows, sensitive data, complex logic | Simple trigger-action, fast setup | Visual complex flows, no self-hosting needed |
FAQ
What is n8n?
n8n is an open-source automation platform that connects apps and AI models through a visual builder, with a self-hosted option for full data control.
Is n8n free to use?
Free to self-host. n8n Cloud offers paid plans for teams that prefer managed hosting without server management.
How does n8n differ from Zapier?
n8n offers complex branching logic, JavaScript customization, and self-hosting. Zapier is simpler to set up but has fewer customization options.
Can n8n connect to AI models like Claude or GPT?
Yes. n8n has native nodes for Anthropic Claude, OpenAI, and other AI APIs, making it a common choice for AI-powered automations.
Do I need coding skills to use n8n?
No coding is required for most workflows. JavaScript knowledge helps for advanced data transformations but is not needed for standard automations.
