Power Automate is excellent for Office 365 workflows. n8n is the right tool when those workflows get complex, cross system boundaries, or need to scale without ballooning your licensing bill. Here's exactly how we think about the choice.

Both tools can automate workflows. Both have hundreds of connectors. Both are used by serious businesses.
But they're designed with different assumptions, and choosing the wrong one for your use case creates problems that compound over time — either in cost, in capability, or in the maintainability of the workflows you build.
Here's how I actually think about the decision.
If your business runs on Microsoft 365, Power Automate has a real home-court advantage.
SharePoint integration is native. Approvals, list triggers, document events — Power Automate handles these without any configuration overhead because it shares an identity layer with SharePoint. SPFx components can trigger flows directly. Power Automate knows who the user is, what their role is, and what permissions they have, without you having to pass tokens around.
Microsoft Teams approvals. The Adaptive Card approval experience in Teams is polished and built-in. Users get an approval card in Teams, click Approve or Reject, and Power Automate handles the rest. Building something equivalent in n8n requires more assembly.
No-code, truly. Power Automate's design surface is genuinely accessible to non-developers. If your goal is to empower a business user to build and maintain their own workflows without touching anything resembling code, Power Automate is easier to hand off.
Included in most Microsoft 365 plans. If you're already on M365 Business Premium or E3/E5, you have Power Automate at no additional cost for standard connectors.
Cost at scale. Power Automate's premium connectors (Salesforce, ServiceNow, most non-Microsoft APIs) require a premium licence or a per-flow plan. If you're running complex workflows that touch multiple external systems, the costs escalate quickly.
n8n charges per workflow execution (on cloud) or is free on self-hosted. It has no concept of "premium connectors." Every integration costs the same: nothing extra.
The Code node. This is n8n's biggest capability advantage. Mid-workflow, you can drop into a Code node and write JavaScript to transform data in ways that no visual connector can handle. Complex string parsing, custom business logic, building an API request payload with dynamic structure — you do it directly in code.
Power Automate's "Run Script" actions exist, but they're scoped, harder to debug, and not available on every plan.
Debugging is transparent. When an n8n workflow fails, you get the full execution log — every node's input and output, the exact error message, the specific record that failed. You can rerun individual nodes with the exact data that caused the failure.
Power Automate's run history is significantly less useful. Error messages are often generic. Rerunning a failed flow reruns the whole thing from the beginning.
No vendor lock-in. n8n workflows are stored as JSON. You can export them, version-control them in git, migrate them between environments, and back them up trivially. Power Automate flows live in your Microsoft tenant — exported formats are limited and re-importing is unreliable.
Self-hosted option. A self-hosted n8n instance on a $10/month server handles thousands of workflow executions with no usage-based costs. For high-volume automations, this makes the economics dramatically better than any cloud-based alternative.
Let's say you're running 20 workflows that each touch Salesforce, SharePoint, and a custom API.
In Power Automate, those external connectors require either a Power Automate Premium licence ($15/user/month) per user who triggers or owns the flows, or a per-flow plan ($500/flow/month for attended, $100 for unattended via Process plans). For 20 flows hitting premium connectors, you're looking at significant monthly spend.
In n8n Cloud, those same 20 workflows cost $50/month on the Starter plan (up to 10,000 executions), with no distinction between "standard" and "premium" connectors. Salesforce and a custom API cost the same as sending an email.
Self-hosted n8n: approximately $10-15/month for the server. That's it.
These tools aren't mutually exclusive. In Microsoft-heavy environments, we often use both:
The two platforms can coexist and even interact — a Power Automate flow can call an n8n webhook, and vice versa. We design the automation architecture to use each tool where it's strongest, rather than forcing everything through one.
Ask these questions:
Most businesses benefit from having both tools available and choosing deliberately for each automation rather than defaulting to one.
