We use n8n for almost everything we build at ShipWorkflow. That's not a sponsorship — it's a decision we made after using both tools on real client projects and hitting the limits of each.

Here's an honest breakdown of where each one wins, and which you should be using at your scale.

The short answer

If you're an agency building automation systems for clients, or running your own operations at any meaningful volume, n8n is the better tool. If you're a solo founder automating one or two personal workflows at low volume, Zapier is fine.

The gap between them grows the more seriously you take automation.

Cost at agency scale

This is where the difference is most stark. Zapier charges per task — every action in every workflow counts toward your monthly limit. At a small personal scale, that's manageable. At agency scale, it becomes expensive fast.

A typical agency automation system — client onboarding, reporting, lead follow-up, invoicing — might run 15,000–30,000 tasks a month. On Zapier's Professional plan, that puts you at £350–600/month, scaling upward as you grow.

n8n cloud charges a flat monthly fee regardless of how many tasks you run. Self-hosted n8n on a basic VPS costs under £10/month and runs unlimited workflows. For agencies with multiple clients, the arithmetic is obvious.

Flexibility and logic

Zapier's workflow model is linear — trigger, then a sequence of actions. It handles simple flows well. The moment you need conditional logic, loops, or complex branching, it starts fighting you.

n8n supports:

  • Custom JavaScript and Python inside workflow nodes — so you can transform data, call APIs, and handle edge cases that no native integration covers
  • Complex branching with multiple conditions and fallback paths
  • Loops for processing batches of data
  • Direct HTTP requests to any API, including ones with no native n8n integration
  • Sub-workflows that can be called from parent workflows — useful for building modular, reusable automation components

For the kinds of systems we build — multi-step onboarding flows, payment lifecycle management, cross-platform data orchestration — n8n's flexibility isn't optional. These systems couldn't be properly built in Zapier.

Data ownership

Zapier is cloud-only. Every piece of data flowing through your workflows passes through Zapier's servers.

n8n can be self-hosted. For agencies handling client data — contact records, payment information, business metrics — this matters. Self-hosted n8n means your data stays on your infrastructure. No third party processes it.

For clients in regulated industries, or any client who has asked you about data handling, self-hosted n8n is the answer Zapier simply can't give you.

Where Zapier genuinely wins

Native integrations. Zapier has thousands of pre-built app connections with polished, maintained integration nodes. For common tools — Gmail, Slack, HubSpot, Salesforce — Zapier's integrations are often easier to set up than n8n's, which sometimes require more configuration.

If you're connecting two mainstream tools with a simple trigger-action flow, Zapier's setup time is shorter. For those specific use cases, that convenience has real value.

Zapier is also the better choice for non-technical users who need to build and maintain automations themselves. The interface is more approachable for people who don't want to think about data structures or API calls.

Make (formerly Integromat)

Worth mentioning because it sits between the two. Make is cloud-based with a visual interface similar to n8n. Its pricing model is more competitive than Zapier's at moderate volumes. It's a solid alternative if you want cloud hosting without Zapier's task-based pricing.

We chose n8n over Make primarily for the self-hosting option and the ability to write custom code inside workflows. Make can't do the latter.

Our recommendation for agencies

Use n8n. Self-host it if you handle sensitive client data or want unlimited scale. Use n8n cloud if you want managed infrastructure without server management.

The learning curve is real — n8n requires more technical comfort than Zapier. But the ceiling is also dramatically higher, and the cost savings at any serious volume are significant.

If you want n8n set up and running for your agency without the learning curve, that's exactly what we build. We design the architecture, build the workflows, handle the hosting, and hand you a system that runs without you.
