Power Automate vs n8n: Which to Choose for a Microsoft 365 Business

By Edward Pinela — Microsoft-certified consultant · October 3, 2026

Power Automate vs n8n is rarely a question about which tool has more integrations. It is a question about who runs the platform. Power Automate is a managed service inside your Microsoft 365 tenant, licensed per user and governed by the same admin center as everything else you own. n8n is a workflow engine you can host yourself, on your own server, under a source-available license — or rent as a cloud service billed by workflow execution. One hands operations to Microsoft; the other hands them to you, along with a great deal of freedom.

If your shortlist also includes a hosted SaaS tool, our Power Automate vs Zapier comparison covers that trade-off. This page is about the self-hosted, developer-friendly alternative — and about AI agents, where n8n has become a common first stop.

The short version

For a Microsoft 365 business whose automations are mostly approvals, document routing, Teams notifications and SharePoint updates, Power Automate is usually the better home: the standard connectors are seeded into most business plans, flows inherit your Entra ID identities and data policies, and there is no server to patch. n8n wins when a technical team wants full control of where the engine runs, needs to keep workflow data on infrastructure it owns, runs high-volume developer-owned integrations, or wants to experiment with AI agents on whichever model provider it chooses.

Self-hosting vs Microsoft's cloud

This is the real dividing line. n8n can be installed on a server or container you control, or used as n8n's own cloud service. Self-hosting means workflow data, credentials and execution logs never leave infrastructure you choose — which is the reason some teams pick it. It also means you own uptime, backups, database growth, upgrades, security patching and the credential store. A self-hosted instance is a production application, and it needs an owner the way any production application does.

Power Automate has no self-hosted option for cloud flows; Microsoft runs the service and you configure it. For a small IT team that is the point: there is no server to keep alive, and flows run in the same tenant and region as your Microsoft 365 data. The exception is desktop flows, which run on Windows machines you provide so robotic process automation can drive legacy applications that have no API — something n8n does not offer as a built-in capability.

n8n's license matters here too. It is published under n8n's own Sustainable Use License, which permits use for your own internal business purposes but is not an open-source license in the standard sense, and some enterprise features sit under a separate commercial license. For a company automating its own processes that is usually fine; it is worth knowing before anyone describes the choice as “free and open source.”

Cost: flat infrastructure vs per-user licensing

The two products meter on different axes. n8n's cloud plans are priced on monthly workflow executions, where one execution is a full run of a workflow no matter how many steps it contains. Self-hosted community edition has no license fee at all, so the cost is flat: the server, the database, and the time of whoever maintains it — and that cost does not move when you add another user or another hundred workflows.

Power Automate meters on people and processes. Most Microsoft 365 business plans include seeded rights for flows that use standard connectors such as SharePoint, Outlook, Teams and OneDrive, so a typical approval flow often adds nothing to the bill. Premium connectors, Dataverse and desktop flows need a paid plan — Premium is $15 per user per month, with per-process licensing for automations that run unattended. Microsoft's Power Automate licensing documentation (opens in new tab) sets out which capabilities each plan covers, and our guide to Power Automate licensing for small business works through when a seat is actually needed.

The honest comparison is total cost, not license cost. If you already have someone who runs Linux containers and Postgres for a living, self-hosted n8n can be very economical for high-volume integrations. If you do not, the hours spent operating it usually outweigh what a handful of Premium seats would cost — and seeded Microsoft 365 rights mean many workloads never need a seat at all.

Side-by-side comparison

Both platforms trigger on events, branch, loop, handle errors and call any HTTP API. The differences that decide the choice for a Microsoft 365 business are hosting, metering, governance and how each approaches AI.

AI agents: n8n's AI Agent node vs Copilot Studio

Much of n8n's recent attention comes from AI. Its AI Agent node lets you connect a chat model and one or more tools, and the agent decides which tools to call to complete a task — all inside an ordinary workflow, so the agent can sit between a trigger and the rest of your automation. You choose the model provider and supply its API key, which means model usage is billed by that provider, separately from n8n. That flexibility is genuinely useful for back-office agents: classifying inbound email, extracting fields from documents, or enriching records before they land in a system of record.

Microsoft's equivalent is Copilot Studio (opens in new tab), and it is aimed at a different starting point. Copilot Studio agents publish into Teams and Microsoft 365 Copilot, ground their answers in SharePoint and other Microsoft 365 knowledge sources with the user's own permissions applied, and call Power Automate flows and connectors as actions. If the people using the agent already live in Teams, and the knowledge it needs sits in SharePoint, you inherit identity, publishing and permission trimming rather than building them. If you want help scoping that, our Copilot Studio consulting services build agents on exactly that pattern.

The practical test: an agent that talks to employees about company knowledge belongs in Copilot Studio; an agent that works unattended inside a data pipeline, where model choice matters more than Teams publishing, is a reasonable fit for n8n.

Governance: who answers the audit question

Power Automate's governance comes from the tenant. Flows sit in environments, run under Entra ID identities, and are subject to Power Platform data policies that let an admin block risky connector combinations outright — Microsoft's guidance on data loss prevention policies (opens in new tab) explains how connectors are grouped and restricted. When someone leaves, their account is disabled in one place. That does not make sprawl impossible, which is why we run Power Platform governance consulting for estates that have grown past the point anyone can list them.

With n8n, governance is whatever you build. On a self-hosted instance, the credentials for every connected system live in n8n's own store, so securing that store, the host and its backups is your responsibility. Single sign-on, Git-based environments and finer-grained roles are tied to n8n's paid plans. And every Microsoft 365 connection runs through an Entra app registration whose Graph permissions someone has to approve — broad permissions granted once for convenience are a common audit finding. None of this rules n8n out; it means someone technical has to own it on purpose.

When each one wins for a Microsoft 365 business

Choose Power Automate when the process touches internal documents, approvals, Teams or SharePoint; when business users rather than developers will build and maintain flows; when an application with no API sits in the middle; or when compliance needs one admin center and one identity system. Choose n8n when you have engineers who want to own the runtime; when workflow data must stay on infrastructure you control; when integrations are high-volume and developer-owned; or when you want to build AI agents inside pipelines on a model provider of your choosing. Running both is workable if the boundary is written down — running both by accident is how a company ends up with two credential stores and nobody sure which one sends the invoices.
