n8n Review

What n8n actually does

n8n is an open-source, self-hostable workflow automation platform — the engineer-friendly alternative to Zapier and Make. The core abstraction is the same (triggers, nodes, connections), but n8n was designed from the start to handle complex workflows with conditional logic, custom code nodes, and engineering-grade reliability. The product runs as a Node.js application, which means you can self-host it on a $5 VPS and pay nothing in licensing.

The AI features have grown into a significant part of the platform. Native nodes for OpenAI, Anthropic, Hugging Face, and a generic LLM node that wraps any provider. There's also an AI Agents builder (using LangChain primitives) for multi-step reasoning workflows. The overall posture is "give engineers serious tools" rather than "make automation easy for non-technical users."

What works well

The ability to drop into JavaScript code anywhere in a workflow is the killer feature for engineering-led teams. Anything you can't express with the standard nodes, you write in a code node. This eliminates the workflow-platform-then-custom-code split that often hits Zapier users at scale.

The self-hosting story is genuinely good. A production n8n instance runs reliably on modest hardware, has proper Docker images, supports horizontal scaling, and includes queue mode for long-running workflows. For teams with security or data-locality requirements, this is the only major workflow platform that meets the bar.

The AI agent nodes are more mature than Zapier's equivalent. Memory, tool use, multi-step reasoning, and structured outputs all work as advertised, with enough escape hatches to debug when they don't.

Where it falls short

The UI assumes more technical literacy than Zapier or Make. Non-engineers can build simple workflows but hit a glass wall as soon as conditional logic or data transformation gets non-trivial. n8n is not the right pick for a marketing manager who wants to automate their own workflows.

Integration breadth is meaningful (~400 nodes) but materially less than Zapier's 7,000+. For obscure SaaS tools, you may need to use the generic HTTP node, which works but takes more setup.

The cloud product (n8n.io hosted) is reasonably priced but the self-hosted Community Edition is missing some features (SSO, sourcecontrol, certain enterprise governance) that are reserved for the paid Enterprise tier. Read the license carefully before assuming you can use everything for free.

Who should use it

n8n is the right pick for engineering-led teams that want serious automation infrastructure with self-hosting and code-level control. It is also the right pick for any team with data-residency requirements that exclude SaaS workflow platforms.

Non-technical operators are better served by Zapier. Teams that need 7,000+ integrations more than they need code-level flexibility are also better served by Zapier.

Pricing notes

Self-hosted Community Edition is free for unlimited workflows. n8n Cloud starts at €20/mo for the Starter tier with execution limits. Enterprise self-hosted is custom-priced and includes SSO, Git integration, and advanced governance.

The agent-program gap

n8n is excellent infrastructure for executing workflows that an agent decides to run. But n8n itself doesn't decide which workflows to create, when to modify them, or how to coordinate across many automations toward a business outcome. The orchestration layer that makes those decisions is the agent program; n8n is the executor that program calls into.
