Short answer: choose Zapier when a non-technical team needs to connect popular SaaS apps quickly; Make when you want a visual builder with more control over branching and data; n8n when you want to self-host, keep data on your own servers and run complex or high-volume workflows without per-task fees; and custom code when the workflow is core to your business, runs at high volume, or needs proper testing, version control and audit trails. Most growing companies end up with a mix.

Zapier: fastest for simple app-to-app tasks
Zapier connects thousands of SaaS apps with simple triggers and actions: a new form entry becomes a CRM contact and a Slack message. It is ideal for small teams and quick wins. It becomes expensive and hard to manage when workflows multiply, branch heavily or run at high volume.
Make: more control, still visual
Make (formerly Integromat) shows each scenario as a visual flow with routers, iterators and data mapping. It handles more complex logic than basic zaps and suits operations teams who are comfortable with data structures.
n8n: self-hosted power for technical teams
n8n can run on your own server, so customer data never passes through a third party, and costs do not rise with every task. It supports code steps, webhooks, databases and AI agent nodes. You take on hosting, updates, backups and monitoring, or hire someone who does.
Custom code: for workflows that run the business
When a workflow handles payments, orders, payroll or thousands of events a day, we write it as a proper service: queues and retries, idempotency so nothing runs twice, tests, version control, monitoring and alerts. It costs more to build and far less to run at scale, and nothing breaks when a vendor changes its pricing.
Where AI agents fit
All four can call ChatGPT, Claude or Gemini. For a simple "summarise and route this email" step, a no-code AI step is enough. For agents that use many tools, need approvals and must explain what they did, a custom agent or an MCP server gives you control and audit logs. See agentic AI systems.
How to decide in five questions
- How many runs a month, now and in a year?
- Does the data have to stay on your servers?
- Who will maintain it when the builder leaves?
- What happens if a run fails silently?
- Is this workflow core to how you make money?
If the answers are "low, no, anyone, nothing much, no", start with Zapier or Make. If they are "high, yes, our tech team, a lot, yes", use n8n self-hosted or custom code.
A common path
Start with a no-code tool to prove the workflow, measure the time saved, then move the busiest or most critical workflows to n8n or code. Keep simple ones where they are.

Frequently asked questions
Is n8n better than Zapier?
Neither is better for everyone. Zapier is the quickest way for non-technical teams to connect popular SaaS apps. n8n suits teams that want to self-host, keep data on their own servers, build more complex logic and avoid per-task pricing at high volumes.
Can n8n be self-hosted?
Yes. n8n can run on your own server or cloud account, which keeps workflow data inside your infrastructure. It is distributed under a fair-code licence, so check its terms if you plan to resell it or embed it in a product.
When should we use custom code instead of a no-code tool?
When volume is high, when workflows need strict error handling, testing and version control, when the process is core to your business, or when per-task fees grow faster than the value. Many companies start in a no-code tool and move the busiest workflows to code later.
Can these tools run AI agents?
Yes. n8n, Zapier and Make all offer AI steps and agent features that call models such as ChatGPT or Claude. For agents that need many tools, long memory, approvals and audit logs, a custom agent or an MCP-based design is usually more reliable.
How long does it take to automate a business workflow?
A single workflow in a no-code tool can be live in days. A set of connected workflows across CRM, ERP, email and WhatsApp, with error handling and monitoring, typically takes two to five weeks.
