What Is n8n?
n8n is an open-source, self-hostable workflow automation tool that connects the apps, APIs and AI models a business already uses. It lets teams build automated processes visually, without having to write code from scratch, and it sits in the same category as Zapier and Make. The difference is that n8n can be hosted on your own server, which gives you more control over your data and removes per-task fees on high-volume work.
The name is pronounced "n-eight-n" and is always written in lowercase. Because it is open-source, the core software is free to use, and a large community contributes integrations and templates. Businesses that want a managed option can also use the paid n8n cloud service rather than running their own server.
At its heart, n8n is about connecting systems. A typical workflow might take a new enquiry from a website form, add it to a customer relationship management (CRM) system, notify the sales team on Slack, and send the customer a confirmation email, all without anyone touching a keyboard. It can connect to hundreds of services and to any tool that offers an API.
How n8n Works
n8n workflows are built on a visual canvas made up of nodes. Each node represents a single step, such as fetching data, transforming it, or sending it somewhere. You connect nodes together to define the order in which steps run, and data flows from one node to the next.
Every workflow starts with a trigger. A trigger is the event that sets the workflow off, such as a new email arriving, a form being submitted, a scheduled time of day, or an incoming webhook from another system. Once triggered, the workflow runs through its connected nodes in sequence, with branching logic where it is needed.
Most workflows are built with no code at all, by configuring nodes through simple forms. For more advanced cases you can drop in custom JavaScript or Python, which means n8n scales from a quick two-step automation to a complex process with conditional logic, loops and error handling.
How Businesses Use n8n
South African businesses use n8n to remove repetitive manual work and to join up tools that do not talk to each other on their own. Common uses include routing new leads from ads and forms straight into a CRM, syncing customer records between systems, and building automated reporting that pulls figures from several platforms into one place.
n8n is also increasingly used to build AI-agent workflows. Because it connects to large language model providers, a workflow can read an incoming message, ask an AI model to draft a reply or summarise a document, and then act on the result. This makes it a practical backbone for marketing automation, support triage and internal operations.
For a marketing team, that might mean automatically tagging and nurturing leads, scheduling content, or sending alerts when a key metric changes. The value is consistency: tasks happen the same way every time, faster than a person could manage, and the team is freed to focus on work that needs judgement.
Common n8n use cases in marketing
n8n is a workflow automation tool that connects apps and services so tasks run automatically, and in marketing it handles the repetitive integration work that otherwise consumes time. Common uses include syncing leads from a form or ad platform into a CRM or email tool; enriching and routing enquiries to the right person or system; posting or scheduling content across channels; pulling data from several sources into a report; and triggering follow-up actions when an event occurs, such as a purchase or sign-up. Because it connects many tools through a visual workflow, it lets a marketing team automate processes that span systems, reducing manual data-shuffling and the errors that come with it, without building custom software for each integration.
Self-hosting and control with n8n
A distinguishing feature of n8n is that it can be self-hosted, run on your own server or infrastructure, as well as used as a hosted service. Self-hosting appeals to businesses that want control over their data and lower per-execution costs at scale, since sensitive information can stay within their own environment rather than passing through a third-party platform, which matters for privacy and compliance. It is source-available and highly flexible, supporting custom logic and many integrations, which makes it powerful for teams with some technical capability. The trade-off is that self-hosting requires setup and maintenance, so businesses without technical resources may prefer the hosted option or a simpler tool. The choice depends on how much control and customisation you need against how much you can maintain.
FAQ
Is n8n free to use?
n8n is open-source and free to self-host on your own server. There is also a paid cloud plan hosted by n8n for teams that prefer not to manage their own infrastructure. Self-hosting suits businesses that want full control over their data.
How is n8n different from Zapier?
Zapier is a fully hosted service priced per task, while n8n is open-source and can be self-hosted at no per-task cost. n8n gives you more control over complex logic, custom code and data privacy, which makes it a strong fit for teams running high volumes of automation.
Do you need to code to use n8n?
No. Most n8n workflows are built visually by connecting nodes on a canvas, with no code required. For advanced cases you can drop in custom JavaScript or Python, so it scales from simple automations to complex technical workflows.
What is n8n used for?
Automating workflows that connect different apps and services, such as syncing leads into a CRM, routing enquiries, posting content, consolidating data into reports, or triggering follow-ups when events occur. It reduces manual, repetitive integration work across the tools a marketing team uses.
Can you self-host n8n?
Yes. n8n can be self-hosted on your own infrastructure as well as used as a hosted service. Self-hosting gives control over data and can lower costs at scale, but requires technical setup and maintenance, so it suits teams with some technical capability.
