If you decide to automate, sooner or later you'll run into the question: n8n or Zapier? Both promise the same thing — connect your systems without writing code — but they behave very differently once things get serious. In this article we're not declaring a winner; instead, we show you which decision point favors which tool.

The difference between the two, briefly

Zapier is a service: you sign up, click things together, it runs. It comes with thousands of ready-made integrations and is designed so that even non-technical people can use it comfortably.

n8n is a tool you have to run somewhere: in their cloud, or self-hosted on your own server. In exchange, it lets you go much deeper — branches, loops, custom code snippets, and your data doesn't have to leave your server if you don't want it to.

The five decision points

1. How many operations run per month?

Zapier charges per run. As long as we're talking about a few hundred steps a month, this is perfectly fine. But once a webshop's every order triggers three or four steps, the monthly bill grows surprisingly fast. n8n, self-hosted, means a cost independent of volume: you pay for the server, not for the steps.

Rule of thumb: for high-volume, repetitive data movement, n8n eventually becomes cheaper.

2. How complex is the logic?

Zapier is fundamentally linear: this happens, then this, then this. There are branches and filters, but complex processes quickly become hard to read. n8n is a visual graph: you can branch, merge branches back together, loop through a list, define an error branch. If your process has a lot of "if this, then that, but only if this other thing," n8n is the way to go.

3. Where can your data be?

This is the toughest consideration, and many people think about it too late. If customer data, health data, payroll information, or trade secrets pass through the process, it matters which server it touches. Running n8n on your own infrastructure means the data never leaves your environment. With Zapier, it's an external data processor that needs to be covered by a contract and a privacy notice.

4. Is there a ready-made integration for what you use?

Zapier is stronger here: the number of ready connectors is an order of magnitude larger, and even niche SaaS tools are often already supported. With n8n, you'd typically solve this with a generic HTTP call — fully workable, but it requires technical know-how. For Hungarian software (invoicing, ERP systems), you typically have to build on the API either way.

5. Who's going to maintain it?

Automation isn't a finished project, it's a living system: APIs change, processes grow, errors need handling. If there's no one at the company who's interested in this, and there's no external partner behind it either, Zapier's simpler operation is a real advantage. n8n, together with its own server, is also an operational task: updates, backups, monitoring.

Instead of a summary table: when to choose which

Choose Zapier if…

• you want to connect a few simple processes quickly,
• a non-technical colleague will manage it,
• your monthly run count is low and predictable,
• it doesn't involve sensitive data.

Choose n8n if…

• a lot of operations run, and the cost matters,
• the logic is complex, with branches and error handling,
• sensitive data also passes through the process,
• you need to work with custom APIs and your own systems,
• there's someone to operate it — even as a partner.

In practice, it's often both

You don't have to pick a religion. At many of our clients, the two run side by side: the team clicks together the smaller marketing and sales automations in Zapier themselves, while the high-volume processes moving financial and customer data live in a self-hosted, supervised n8n instance. This split usually comes down to who's going to edit the given process.

What gets done wrong with both the same way — or rather, shouldn't be

1. Starting without error handling. If a run fails, someone needs to find out. Without a notification, the process silently stops, and it only comes to light weeks later.
2. Not building in a test environment. A half-finished workflow writing into the live CRM is an expensive lesson.
3. Leaving it undocumented. Six months from now, even you won't remember why that filter is there.
4. Hardcoding secrets. An API key written straight into the process body will leak sooner or later. Use managed credentials.

We work with both tools, and it usually comes down to the specifics of the process which one is the right call. If you have a concrete task in mind, write to us — we'll tell you which one we'd use to solve it, and why.
