How to choose a process automation platform – Power Automate, n8n or Make

Power Automate is Microsoft's platform and an integral part of Power Platform. Philosophy: workflow as a native citizen of the Microsoft 365 ecosystem with deep integration to SharePoint, Teams, Outlook, Dynamics, Entra ID. Targets IT and business together.

n8n is an open-source workflow platform written in Node.js with self-hosted or cloud (n8n.io) options. Philosophy: maximum control over data and cost through self-hosting, the option to write custom nodes in JavaScript, integrations via REST APIs. Targets technical teams.

Make (formerly Integromat) is a visual, cloud-only platform, strongest in marketing automation, e-commerce and SaaS integrations. Philosophy: rapid 'glueing' of SaaS apps through an intuitive visual editor. Targets business, marketing and operations.

All three philosophies handle similar basic scenarios (when A → do B), but differ deeply in: native integrations, permission model, governance maturity, self-host vs. cloud, scale economics and customisation depth.

The choice should rest on a structured comparison, not intuition. The table below shows the dimensions we discuss with enterprise clients – from native integrations to vendor lock-in. The intent is not to rank but to differentiate – which profile fits which organisation.

Power Automate is the natural choice for organisations already on Microsoft 365 and Power Platform. Deep integration with SharePoint, Teams, Outlook, Dynamics 365 and Entra ID means workflows handling company documents, approvals and processes inherit security, audit and identity from the Microsoft ecosystem.

The strongest arguments for Power Automate are: ready connectors for every Microsoft product, permission model via Entra ID, DLP policies in the Power Platform CoE, integration with Copilot Studio for the AI layer, and the fact that approval workflows plug natively into Teams as adaptive cards. These elements together are hard to replicate in another tool.

Power Automate has three weaknesses. First, vendor lock-in – a workflow built in Power Automate is practically impossible to move off Microsoft. Second, premium connector cost – integrations with non-Microsoft systems (Salesforce, HubSpot, Slack, Notion) require premium licences that grow expensive at scale. Third, performance at very high volumes – Power Automate has per-licence limits that become noticeable at 100k+ operations per month.

n8n shines where the organisation wants maximum control over data and costs and has technical teams that can maintain a self-hosted infrastructure. The open-source philosophy enables full customisation – custom nodes in JavaScript, custom logic, custom integrations over HTTP.

The strongest arguments for n8n: self-host means workflow data does not leave the client's infrastructure – critical for regulated sectors (medtech, fintech, public sector). The absence of per-user/operation licences removes the scale cost barrier (1M+ operations per month costs about what the infra costs). The open codebase removes vendor lock-in – workflows are exportable as JSON, infra is portable.

n8n has three limitations. First, it requires a technical team – self-host needs DevOps/platform engineering, monitoring, backup, security patching. Without such a team, n8n becomes an operational risk. Second, native Microsoft 365 integrations are shallower than Power Automate (no deep SharePoint metadata integration, no native adaptive cards in Teams). Third, governance maturity – n8n has no equivalent of the Power Platform CoE Toolkit; governance must be built by hand.

Make (formerly Integromat) shines in marketing automation, e-commerce and SaaS integrations. The visual scenario editor lets business and marketing teams build advanced integrations without code. The 1500+ app catalogue covers most common SaaS tools (HubSpot, Mailchimp, Shopify, Airtable, Notion, Calendly, Stripe).

The strongest arguments for Make: speed to production (workflows in hours, not days), the most intuitive UI of the three, a rich SaaS application library, advanced routing and aggregation functions for marketing scenarios. It works best when automation involves non-Microsoft SaaS.

Make has three limitations. First, cloud-only – no self-host, no EU on-premise. For regulated data this is often a deal-breaker. Second, no custom code execution – workflows are visual, but you cannot run your own JavaScript/Python. More complex logic needs external functions (AWS Lambda, Azure Functions). Third, weaker enterprise integrations – Make is strong in SaaS, weaker in on-premise and classic enterprise systems (SAP, Oracle, IFS).

In practice, most mature enterprise organisations do not pick 'one tool for everything'. Each platform excels in a different profile – trying to stretch one across all of them ends in compromise across all areas.

The most common production pattern is: Power Automate as the main platform (all document workflows, approvals, Microsoft 365 integrations) plus a complement chosen for specific needs. n8n as a complement for scenarios needing self-host, custom code or integrations beyond Microsoft. Make as a complement for marketing and SaaS-heavy areas.

Strategically, the key is to have a clear model of when which platform applies and what scenarios belong where. Without it, the organisation ends up with three platforms doing the same thing because each team picked its favourite. That scenario is more expensive than one platform and more complex than a deliberate hybrid.

Workflow security has three layers: platform access (who can build/edit workflows), data access (what data a workflow may process) and audit trail (who did what).

Power Automate inherits security from Microsoft 365 – Entra ID for identity, DLP policies in the Power Platform CoE, data classification through sensitivity labels, audit in Microsoft Purview. It is a ready enterprise-grade stack. Self-hosted n8n means security must be designed from scratch – RBAC, SSO integration, audit logging, network isolation. It takes effort but yields full control. Make has its own permission model through workspaces but limits self-host – unacceptable for regulated data.

For scenarios with sensitive data (personal data, financial data, medical documentation, IP) it is worth remembering the wider context of AI governance and the AI on-premise vs cloud architectural decision – workflow often enters the same discussions.

The most common mistake when choosing a platform is comparing entry pricing, not TCO. Power Automate in a Microsoft 365 organisation has effectively zero entry cost (included in the licence). Self-hosted n8n has zero licensing cost but real infra cost (~$200–500/month for mid scale) plus maintenance (part of a DevOps FTE). Make starts at $9 but grows exponentially with operation count.

TCO for a mid-size organisation (1,000 employees, ~50k operations/month) usually looks like: Power Automate $30–60k yearly (with premium connectors), n8n $15–30k (infra + 0.2 DevOps FTE), Make $20–40k (licences with no maintenance burden).

For an enterprise organisation (10k+ employees, 500k+ operations/month) scale changes the picture: Power Automate $200–500k yearly, n8n $30–60k (infra scales slower than per-user licences), Make $150–300k. n8n becomes the most economical, but only if the organisation has the team to maintain it.

Key: TCO calculation must include not just licences but maintenance, integration with the rest of the architecture and the cost of migration if the decision changes.

Is n8n suitable for enterprise? Yes, with operational maturity. A self-hosted setup with SSO, monitoring, backup and security is standard work to design. More and more large companies (Adidas, Booking, Deutsche Telekom case studies) run n8n in production.

Does Make replace Zapier? In most SaaS scenarios – yes, it is more advanced and cheaper at scale. For simple 1:1 integrations Zapier is still faster to start.

Can I use Power Automate outside Microsoft 365? Yes, but you lose most of the advantages. Power Automate Standalone exists, but deep SharePoint and Teams integration becomes less relevant. Connectors to other SaaS remain (premium versions).

Does a Power Automate + n8n hybrid make sense? Yes. Power Automate for 'standard' workflows in M365, n8n for custom scenarios, self-host and non-Microsoft integrations. Key: a clear policy on what goes where.

How long does platform migration take? Individual workflow – hours to days. Organisation migration of 200 workflows – 6–12 months. Migration is expensive, which is why the first choice has a long horizon.

Do AI workflows (Copilot, agents) change platform choice? Yes. Power Automate has native integration with Copilot Studio and Azure OpenAI. n8n has nodes for OpenAI/Anthropic/Gemini and LangChain. Make has an OpenAI module. AI-heavy scenarios in Microsoft – Power Automate; custom AI workflows – n8n.

Workflow automation platform choice is today one of the most long-term technology decisions in an organisation. It determines who maintains your processes in two years, how much they cost, where your data lives and how easy it will be to change the decision in the future.

Power Automate is right for organisations already on Microsoft 365 with business and IT working together. n8n is right for technical teams seeking control, customisation and vendor independence. Make is right for marketing/e-commerce/SaaS areas where speed of rollout outweighs enterprise governance.

The most sensible first step is not 'we will buy Power Automate because we have Microsoft' but an assessment of the 3 largest workflow use cases, their profile (M365 vs custom vs SaaS) and a fit between platform and these use cases. At AlgorComp we support clients with this decision as part of advisory and strategy engagements.
