About n8n

n8n is a workflow automation tool. You build a process as a chain of connected nodes that pass data between applications, and you can either run it on n8n's cloud or host it yourself under a fair-code licence.

The node library covers more than 500 integrations, and an HTTP request node handles anything outside that list, including importing a curl command directly to build the request. Data transformation nodes provide merge, loop, filter, switch, if, deduplicate, aggregate and split operations. Where the visual editor runs out, the Code node runs JavaScript and Python, self-hosted instances can pull in npm packages, and expressions are written in JavaScript using the Tournament templating language. The AI nodes are built on LangChain and can call local LLMs as well as hosted models. More than 10,000 workflow templates are published as starting points.

Debugging happens inside the editor rather than through logs after the fact. There are inline logs for each line of output, the ability to load a previous execution's data back into the editor, data pinning so a node returns the same result across repeated tests, and single step execution.

Self-hosting is free through the Community Edition. Deployment is by Docker or Kubernetes, including inside air-gapped private networks, and queue mode lets a self-hosted deployment reach up to 220 workflow executions per second. Self-hosted instances ping the n8n licence server daily to report execution usage.

Cloud plans are separated by execution volume rather than by seats, because every plan includes unlimited users and unlimited workflows. Billed annually, Starter costs 20 EUR per month and covers 2,500 executions with unlimited steps each, one shared project and five concurrent executions. Pro costs 50 EUR per month for 10,000 executions, three shared projects and twenty concurrent executions, and adds admin roles, global variables, workflow history and execution search. Business costs 667 EUR per month for 40,000 executions and six shared projects, and adds SSO through SAML and LDAP, 30 day insights, multiple environments and Git based version control. Enterprise is quoted individually. Paying annually rather than monthly saves 17 percent, and Starter and Pro instances are hosted in Frankfurt, Germany.

The enterprise tier is aimed at teams with compliance obligations. It covers identity provider user provisioning, enforced two-factor authentication, custom project roles, external secrets read from HashiCorp Vault, AWS Secrets Manager or Azure Key Vault, and workflow logs streamed to observability or SIEM stacks by direct integration or webhook. Source control follows a Git push and pull pattern between development and production environments. n8n is SOC 2 audited and undergoes regular external penetration testing.

What people use it for

  • Self hosting workflow automation inside an air gapped network where cloud tools are not allowed.
  • Pasting a curl command from an API's docs to build a working request node in one step.
  • Pinning a webhook payload so you can re-run a workflow against the same data while fixing it.
  • Promoting a tested workflow from development to production through a Git pull.
  • Calling a locally hosted LLM from a workflow so prompts never leave your own infrastructure.
  • Halving the Business plan cost as a company with fewer than 20 employees.
  • Keeping cloud workflow data in Frankfurt on a Starter or Pro plan.
