n8n vs Zapier, Why Self-Hosting Wins for Privacy and Cost

Zapier popularized the idea that you shouldn't need to write code to connect two apps together. n8n took that idea and made it self-hostable, open-source, and free of per-task billing. If you're evaluating one against the other, here's how they actually differ once you get past the marketing pages.

Pricing model

Zapier bills by "tasks", each time an automation runs and touches data, that's a task, and plans cap how many you get per month. A busy automation processing webhooks or syncing records can burn through a task allowance fast, and the fix is always the same: upgrade to the next tier.

n8n has no concept of a task limit. Whether a workflow runs once a day or ten thousand times, the cost is the compute it runs on, not a per-execution fee. Once you're self-hosting it, that compute cost is fixed and predictable.

Where your data goes

Every Zapier automation means your data passes through Zapier's infrastructure on its way from one app to the next. For most use cases that's a non-issue. For anything touching customer PII, financial records, or health data, it's a real question you have to answer for compliance.

A self-hosted n8n instance keeps that data on infrastructure you control. The workflow still connects to third-party APIs, that's the point, but there's no additional third party sitting in the middle of every execution.

Integrations and flexibility

Zapier has the edge in sheer number of pre-built app integrations, especially for long-tail consumer SaaS tools. n8n covers the major platforms and fills gaps with its HTTP Request node, which can call any REST API directly, and a visual workflow editor that supports actual code (JavaScript or Python) inside a node when you need logic a pre-built integration doesn't offer.

n8n also ships native support for AI workflows, LLM chains, agents, vector store lookups, that Zapier is still catching up on.

The honest tradeoff

Zapier's tradeoff is real: you pay more, but you don't manage any infrastructure. n8n's tradeoff used to be the mirror image, you pay less, but now you're the one running a server.

That second tradeoff is exactly what self-hosting platforms are meant to remove. Run n8n on your own isolated silo and you keep the cost and privacy advantages without taking on the operations work that used to come attached to them.
