What Is n8n? A Plain-English Guide to Workflow Automation
By Vimehi Team · · AI-assisted content, reviewed by the Vimehi team
If you have heard "n8n" mentioned in conversations about automating business processes and wondered what it actually is — this guide is for you. No technical jargon, no assumptions. Just a clear explanation of what n8n is, how it works, when it makes sense to use it, and what the honest trade-offs are.
n8n (pronounced "n-eight-n", short for "nodemation") is an open-source workflow automation tool. It lets you connect different software tools together and define sequences of automated actions between them. When something happens in one app — a form is submitted, a payment arrives, a record is updated — n8n can automatically trigger a chain of actions in other apps, all without any human involvement.
We use n8n in almost every automation project we build at Vimehi. This guide reflects what we have learned actually running it for clients, not just what sounds good in a product description.
The Core Idea: Connecting Apps Without Code
Most businesses use several different software tools — a CRM, an email platform, a project management tool, a billing system. The problem is these tools do not naturally talk to each other. Data gets copied manually between them. Follow-up emails get sent by hand. Reports get compiled by copying numbers from one spreadsheet to another.
n8n sits in the middle and connects all of these tools. You define workflows — "when X happens in App A, do Y in App B" — and n8n runs them automatically, 24 hours a day, without anyone at a keyboard.
For example: when a prospect fills in your website contact form, n8n can automatically create a contact record in your CRM, send the prospect a personalised email, post a Slack notification to your sales team, and add a task to your project management tool — all within seconds, all without anyone touching it.
How n8n Works: Nodes, Triggers, and Workflows
n8n uses a visual canvas where you build workflows by connecting "nodes". Each node represents either a trigger (what starts the workflow) or an action (what the workflow does). You drag nodes onto the canvas, connect them with arrows, and configure what each one does.
Trigger Nodes
A trigger is what starts a workflow running. Common triggers include: a new form submission on your website, a scheduled time (every day at 9am), a new email arriving, a webhook fired by another system, or a new record appearing in a database. When the trigger condition is met, n8n automatically runs the rest of the workflow.
Action Nodes
Action nodes do things: create a record in HubSpot, send an email via Gmail, post a message to Slack, update a row in Google Sheets, call an external API, run a piece of JavaScript or Python code, or even send a request to an AI model like ChatGPT or Claude to process data. n8n has over 500 pre-built integrations, and a custom HTTP request node that can connect to essentially any system with an API.
The Workflow Canvas
Everything is visual. You see the data flowing through each node in real time during testing, which makes debugging significantly easier than traditional code-based automation. Non-developers can understand what a workflow does by looking at it — though building complex ones still benefits from technical expertise.
n8n vs Zapier vs Make.com: What Is Actually Different
You have probably heard of Zapier or Make.com (formerly Integromat). n8n does the same fundamental job — connecting apps and automating workflows — but with meaningful differences that matter as you scale.
Pricing model: Zapier charges per task (every action in every workflow). At 50,000 tasks per month, that can cost $500–$800/month. n8n self-hosted runs on your own server for roughly $5–20/month with unlimited executions. n8n Cloud is $20–50/month with execution limits, but still far cheaper at volume.
Flexibility: Zapier locks you into pre-built connectors. n8n lets you write custom JavaScript or Python inside nodes, build entirely custom integrations, and create sub-workflows you call like functions. This matters when your use case does not fit a standard template.
AI integration: n8n has native nodes for OpenAI, Claude, and Gemini that let you build AI agents operating inside your workflows — classifying emails, generating content, making decisions. Zapier's AI capabilities are much more limited.
Self-hosting: Zapier is cloud-only. n8n can run on your own server, keeping your business data entirely within your infrastructure. For businesses handling sensitive data, this is a significant advantage.
The trade-off is that n8n requires more expertise to set up and maintain correctly. That is where an n8n agency like Vimehi comes in.
When n8n Makes Sense — and When It Does Not
n8n is the right choice when your automation volume is high (making Zapier expensive), when you need custom logic that standard connectors cannot handle, when you want to keep your workflow data on your own servers, or when you want to embed AI models as decision-makers inside your automations.
It is probably not the right first tool if you have never used any automation platform, want to get one simple automation running in the next hour, and are not ready to invest in setting up infrastructure. In that case, Zapier or Make.com are genuinely easier starting points — you can migrate to n8n later as your needs grow.
At Vimehi, we have migrated many clients from Zapier to n8n, typically reducing their automation costs by 60–80% while giving them significantly more capability. If your current Zapier bill is growing, that conversation is worth having.
Frequently Asked Questions
Is n8n free?
The n8n open-source software itself is free. If you self-host it on your own server, your only cost is server fees (typically $5–20/month). n8n also offers a managed Cloud plan starting at around $20/month if you prefer not to manage infrastructure yourself.
Do I need to know how to code to use n8n?
Basic workflows can be built without coding — n8n has a visual interface and hundreds of pre-built integrations. However, complex workflows involving custom logic, data transformation, or non-standard API integrations benefit significantly from technical expertise. Most businesses get better results working with an n8n specialist.
What apps does n8n connect to?
n8n has over 500 native integrations including HubSpot, Salesforce, Slack, Gmail, Google Sheets, Shopify, WhatsApp Business API, Airtable, Notion, and many more. For anything not natively supported, the HTTP Request node connects to any system with a REST API.
How is n8n different from Make.com?
Both are more flexible than Zapier. n8n goes further by supporting self-hosting (keeping data on your servers), custom code inside nodes, and more powerful AI agent integration. Make.com is cloud-only and has less flexibility for custom logic, but has a slightly gentler learning curve than n8n.
Can n8n replace a developer?
For automation and integration work specifically, n8n can replace a significant amount of custom development. However, setting n8n up correctly — with proper error handling, monitoring, and reliable infrastructure — still benefits from developer-level expertise, either in-house or through an automation agency.
Conclusion
n8n is a genuinely powerful workflow automation platform that can eliminate significant amounts of manual work and connect every tool in your business. The honest caveat is that realising its full potential requires more setup and expertise than simpler tools like Zapier — but it also gives you capabilities and cost efficiency those tools simply cannot match at scale.
If you are curious whether n8n makes sense for your specific business, the fastest answer comes from an honest conversation about what you are currently doing manually. That is exactly what our free automation audit covers.
