n8n — What Is It?

Business process automation in 2026 is not a luxury — it is a standard. Companies that still manually re-enter data from emails into CRM systems, copy information between spreadsheets, and send repetitive messages are losing hundreds of hours of work per month. Tools like Zapier and Make have addressed this problem for years — but they have their limitations: closed code, rising costs at scale, and vendor dependency.

This is where n8n comes in — an open-source workflow automation platform that by 2026 has become a serious alternative to commercial giants. This article explains exactly what n8n is, how it works, what it costs, and when it is worth choosing over Zapier or Make.

n8n in One Sentence

n8n (pronounced “n-eight-n”) is an open-source, self-hostable workflow automation tool that connects applications and services via a visual editor — without requiring you to write code.

The name comes from the word “nodemation” (node + automation). The project was founded in Berlin in 2019 by Jan Oberhauser. By 2026, n8n has over 50,000 stars on GitHub, 400+ built-in integrations, and an active community with thousands of ready-made workflow templates.

The key difference from the competition: you can host n8n on your own server, maintain full control over your data, and pay nothing per execution. This changes the economics of automation — particularly at high scale.

How Does n8n Work? (Visual Workflow Builder)

n8n is built around the concept of a workflow — a sequence of steps (nodes) that execute automatically when a trigger is fired.

Anatomy of a Workflow in n8n

1. Trigger — the event that starts the workflow:

   • Webhook (HTTP request)
   • Cron (scheduled timer)
   • New email in inbox
   • New row in Google Sheets
   • CRM event (new lead, status change)

2. Nodes — individual actions:

   • Fetch data from an API
   • Transform data (filtering, mapping, merging)
   • Send a message (email, Slack, SMS)
   • Write to a database
   • Call an AI model (OpenAI, Anthropic)

3. Connections — lines linking nodes, defining the data flow

4. Execution — every workflow run is a separate “execution” with a full log

Visual Builder — No Code, But With Code Option

The n8n interface is a canvas where you drag and connect nodes. Each node has a configuration panel — you fill in fields, select options from lists, and map data from previous steps.

But n8n is not just no-code. When you need more control, you have:

• Code Node — write JavaScript or Python directly in the workflow
• Function Node — transform data with any code
• HTTP Request Node — call any API with full control over headers and body
• Execute Command Node — run a shell command on the server

This makes n8n a tool for both non-technical users (no-code) and developers (code-first with visualisation).

AI in n8n — Native Integrations

In 2026, n8n offers dedicated nodes for working with AI:

• OpenAI Node — GPT-4, Whisper, DALL-E
• Anthropic Node — Claude
• Google Vertex AI Node — Gemini
• LangChain integration — building AI agents in workflows
• Vector Store Nodes — Pinecone, Qdrant, Weaviate
• AI Agent Node — an autonomous agent with tools and memory

This allows you to build advanced AI pipelines without writing code — for example, an automated assistant that reads emails, classifies them, responds to simple queries, and escalates complex ones to a human.

What Does n8n Cost? (Cloud vs Self-Hosted)

n8n Cloud (hosted by n8n GmbH)

Plan	Price/month	Workflows	Executions	Users
Starter	€20	5 active	2,500	1
Pro	€50	15 active	10,000	3
Enterprise	Custom	Unlimited	Unlimited	Unlimited

n8n Self-Hosted (Your Own Server)

Element	Cost	Notes
n8n licence	Free (fair-code licence)	Free use for companies, resale prohibited
VPS server	$20–100/month	DigitalOcean, Hetzner, OVH — min. 2 vCPU, 4 GB RAM
Database	$0–40/month	PostgreSQL (managed or self-hosted)
SSL + domain	$0–20/year	Let’s Encrypt (free) + domain
Backup	$10–30/month	Automated DB + file backup
DevOps / maintenance	$100–500/month	Updates, monitoring, troubleshooting

Total self-hosting cost: $130–670/month — depending on scale and whether you have in-house DevOps.

When Does Self-Hosting Pay Off?

• Above 10,000 executions per month (Zapier would cost $100+/month)
• When processing sensitive data (GDPR — full control over storage)
• When you need unlimited workflows
• When you have DevOps in-house or a technical partner

When Is n8n Cloud Better?

• Small team without DevOps
• Fewer than 10,000 executions/month
• You need a fast start without server configuration
• You do not want to manage updates and backups

When Is n8n Better Than Zapier/Make?

1. You Have Many Executions and Want to Save

Zapier at 50,000 tasks/month costs over $500. n8n self-hosted at the same volume costs the server — $30–100. At high scale, the savings run into thousands of dollars per month.

2. You Need Full Data Control

For companies in the medical, financial, or legal sectors — processing data on your own EU server is not an option, it is a requirement. n8n self-hosted gives you 100% control over where data is stored and processed.

3. You Are Building Complex Workflows With Business Logic

n8n offers full branching (IF/ELSE/Switch), merge nodes, sub-workflows, error handling with fallbacks, and loops. When your workflow has 50+ steps with multiple decision paths — n8n gives more control than Zapier.

4. You Are Integrating AI Into Processes

Native nodes for OpenAI, Anthropic, LangChain, and vector stores make n8n the ideal platform for building AI pipelines — from a simple “summarise this email” to an advanced agent with memory and tools.

5. You Need Custom Integrations

When the application you want to integrate does not have a ready connector in Zapier — you have to wait for support. In n8n you write your own node or use HTTP Request with full API control.

6. You Want to Version and Test Workflows

n8n allows exporting workflows as JSON, versioning in Git, environment variables, and separate dev/staging/prod instances. This is a software engineering approach to automation — unavailable in SaaS tools.

FAQ

1. Is n8n Really Free?

n8n is open-source under a “fair-code” licence (Sustainable Use Licence). This means: you can self-host n8n for free for your own company, with no limits on workflows or executions. You cannot, however, resell n8n as a service (e.g. offer “n8n as a Service” to clients). For that you need a commercial licence.

2. Is n8n Safe for Company Data?

Yes — with self-hosting, data never leaves your server. n8n does not send telemetry about your data to anyone. You can host in the EU on GDPR-compliant servers, encrypt databases, and apply full backup policies. This is safer than sending data to US-based SaaS platforms.

3. Do I Need a Developer to Use n8n?

For simple workflows (5–15 nodes, standard integrations) — no. The no-code interface is intuitive and well-documented. For complex scenarios (custom nodes, error handling, API integrations without ready connectors) — a technical person is useful. For self-hosting and maintenance — you need DevOps or a technical partner.

4. How Does n8n Handle Large Numbers of Executions?

n8n in queue mode (with Redis and multiple workers) handles tens of thousands of executions per hour. With proper configuration (PostgreSQL, dedicated workers, monitoring) n8n scales horizontally. Companies with 100,000+ executions/month use n8n in production without problems.

5. Can I Migrate From Zapier/Make to n8n?

Yes, though there is no automatic importer. The migration process requires rebuilding workflows manually in n8n — but 80% of integrations have equivalents. The n8n community publishes migration guides. A typical migration of 20 Zaps from Zapier to n8n takes 2–5 working days. It is worth it — because the one-off migration cost pays back in 2–4 months of subscription savings.
