n8n vs Zapier: which one actually costs less at scale?

Comparisons of these two usually stop at the feature table, which is the least interesting part. Both will move data between your tools. The decision is nearly always about cost at your volume and who carries the maintenance, so this walks through both.

The pricing models are not comparable as written

Zapier charges per task, where a task is roughly one action in one run. A workflow with six actions running a hundred times a month is six hundred tasks, not a hundred. This catches people out, because the number that matters is actions multiplied by runs, not the number of workflows you have built.

Self-hosted n8n charges nothing per execution. The cost is a server and your attention. A small instance runs comfortably on hardware costing a few pounds a month, so at the point where task pricing starts to bite, the comparison stops being close.

Three volumes, worked through

• Low, under a thousand tasks a month: hosted wins. The free or cheapest tier covers it, and self-hosting costs you an afternoon of setup to save nothing.
• Medium, ten to fifty thousand tasks: this is the crossover. Hosted plans at this volume cost real money each month, and a self-hosted instance does the same work for the price of a small server.
• High, hundreds of thousands: self-hosted wins by an order of magnitude, assuming somebody is genuinely maintaining it.

The cost nobody puts in the spreadsheet

Maintenance is the variable that decides this and it is the one left out of every comparison. A self-hosted instance needs updates, backups and somebody who notices when it stops. That is perhaps an hour a month when things are calm and an unwelcome evening when they are not.

Price that hour honestly. If an hour of your time is worth more than the difference in subscription cost, the hosted option is cheaper and the spreadsheet saying otherwise is wrong.

Where each one is genuinely better

Zapier has the larger integration library and better error reporting for non-technical users. If the people maintaining your automations are not technical, that matters more than the monthly bill.

n8n handles complex data transformation far better, because you can write code in the middle of a workflow. Anything involving reshaping arrays or conditional branching across several sources is markedly easier.

The pragmatic answer

Start hosted. Build the automation, prove it is worth having, and find out what it really costs to run. Migrate to self-hosted when the bill justifies the maintenance, which for most teams happens somewhere in the medium band above.

Building on self-hosted from day one to save money you are not yet spending is a common and expensive mistake.
