"n8n Review 2026: Open-Source Automation You Can Self-Host"

n8n is a workflow automation tool that sits between Zapier’s simplicity and writing your own scripts. Its node-based editor handles 400+ integrations, but the killer feature is that any node can drop into custom JavaScript or Python — and you can self-host the whole thing on your own server.

How it works#

You build workflows as connected nodes (trigger, HTTP request, function, IF, etc.). The AI node wraps any OpenAI-compatible API for summarisation or agents. Because it is open source under a fair-code license, you can run it on a $5 VPS, keep data on-prem, and version workflows in git.

Strengths#

• Self-hostable — your data never leaves your server
• Code nodes for unlimited flexibility
• 400+ integrations plus raw HTTP
• Generous free self-hosted tier
• Active community and templates

Weaknesses#

• Steeper learning curve than Zapier
• Fair-code license limits some commercial resale
• You own uptime and updates when self-hosted
• UI less polished for pure beginners

Pricing#

• Community (self-host) — $0: Free, yours to run

• Starter (cloud) — $20/mo: Managed, 2,500 executions

• Pro (cloud) — $50/mo: Advanced observability

• Enterprise — custom: SSO, support, scaling

Verdict#

n8n wins for developers and anyone who must keep data in-house. Follow our build-an-AI-agent-with-n8n guide to ship your first one. Compare with Zapier vs Make.
