n8n

Source-available workflow automation you can self-host, with native LLM nodes

The verdict

n8n is a workflow automation tool you can run on your own server, building flows on a visual canvas. It ships LLM and agent nodes, so AI steps sit alongside ordinary app actions.

What it is

n8n builds automations as nodes on a canvas, where each node is an app action, a function, or an AI step. Because you can self-host it, high-volume workflows avoid per-task metering and sensitive data can stay in your own infrastructure. Native nodes for OpenAI, Anthropic and LangChain let you add an agent or an LLM call mid-flow. The catch is operational: you maintain the server, updates and reliability yourself unless you pay for the cloud version, and the connector count trails Zapier's.

Strengths

  • Self-hosting removes per-task fees, so high-frequency flows stay cheap at scale
  • Native OpenAI, Anthropic and LangChain nodes build AI agents inside a normal workflow
  • An HTTP node and function steps let you call any API the connector library lacks

Trade-offs

  • Self-hosting means you own uptime, updates and backups, which is real ongoing work
  • The connector library is smaller than Zapier's, so some niche apps need manual HTTP setup
  • The canvas has a steeper first-hour learning curve than a simple trigger-action builder

Best for

High-volume or data-sensitive automations where self-hosting cuts cost and keeps data in-house

Not for

Non-technical users who want a managed service and the broadest possible app library with zero maintenance

Frequently asked

Can n8n run AI agents?
Yes. n8n has native AI Agent and LangChain nodes plus connectors for OpenAI and Anthropic, so agents and LLM steps live inside ordinary workflows.
Is n8n free?
The self-hosted Community edition is free to run on your own server; managed cloud plans are paid and start in the low tens of dollars per month.
How is n8n different from Zapier?
n8n can be self-hosted to avoid per-task fees and keep data in-house, but it has fewer ready-made connectors and requires more technical setup.
Does n8n require coding?
Basic flows are built visually, but advanced cases use function and HTTP nodes, so some technical comfort helps more than with simpler tools.
Can n8n connect to apps it doesn't list?
Yes. The generic HTTP Request node calls any REST API, so unlisted services can still be automated with manual configuration.
