n8n vs Zapier: Why Self-Hosting Is the Key to Scale

Automation is the backbone of any modern company. For years, Zapier has been the default tool. But there is an inflection point where Zapier stops being a solution and becomes a problem.

The Zapier Ceiling: Costs and Limitations

Zapier is great for getting started, but it has three critical problems for a growing SME:

1. The Per-Task Pricing Model: When you have complex flows processing thousands of data points, the monthly bill becomes absurd.
2. Logic Limitations: Zapier's linear flows fall short when you need advanced conditional logic or complex loops.
3. Data Sovereignty: Your workflows and the data passing through them live on a third party's infrastructure.

n8n: The Freedom of Open Source

n8n is not just an alternative; it is a paradigm shift. By installing n8n on your own server (self-hosted), you remove the restrictions.

Key Advantages of Self-Hosted n8n:

• The Task Is Free: Run a million tasks a month and the cost stays the same: that of your server.
• Native AI Nodes: n8n currently has the best integration with local LLMs, letting you build agents that query your local database without data leaving your network.
• Total Flexibility: You can write JavaScript code directly in any node to manipulate data exactly as needed.

When to Make the Move?

If you are in any of these situations, it is time to migrate:

• You are paying more than €100/month for Zapier/Make.
• You handle sensitive data (customers, finance, health) and want total control.
• Your automation flows require logic that Zapier cannot handle.

The secret of scale: The most efficient companies do not use the "easiest" tool, but the one that gives them total control over their infrastructure.
