Power Automate Desktop vs Online: Key Differences, Features, and Which One You Should Use


In today’s digital world, automation has become a cornerstone of efficiency. Microsoft’s Power Automate platform is one of the most powerful automation ecosystems available, helping individuals and organizations reduce manual work through smart workflows. But one of the most common questions new users face is: What’s the difference between Power Automate Desktop and Power Automate Online?

Although both belong to the same ecosystem, they serve different purposes and operate in different environments. In this article, we’ll compare Power Automate Desktop (PAD) and Power Automate Online (Cloud Flows) — explaining their core features, similarities, differences, use cases, pros, and limitations — so you can decide which version suits your business needs best.

What Is Power Automate?

Before diving into the comparison, let’s clarify what Power Automate actually is.

Microsoft Power Automate (formerly known as Microsoft Flow) is part of the Microsoft Power Platform — a suite of tools including Power BI, Power Apps, and Power Virtual Agents. It allows users to create automated workflows that connect different applications, services, and data sources without complex coding.

Essentially, it helps you automate repetitive tasks, whether that’s sending emails, updating databases, integrating cloud systems, or running desktop processes.

What Is Power Automate Desktop?

Power Automate Desktop (PAD) is the desktop-based Robotic Process Automation (RPA) tool within Power Automate. It allows users to automate actions on their local computer or virtual machine.

You can record mouse clicks, keyboard input, or build complex logic flows that interact with desktop applications, web browsers, and file systems. For example:

  • Copy data from Excel to an internal accounting application.

  • Extract text from PDFs.

  • Upload files to websites.

  • Automate UI-based tasks on Windows applications.

PAD is perfect when your automation needs involve local files, legacy systems, or non-API-based software.

Key features of Power Automate Desktop:

  • Record-and-playback actions (Desktop Recorder, Web Recorder)

  • Drag-and-drop visual designer

  • More than 400 desktop actions

  • Integration with Windows 10/11

  • Ability to run attended or unattended RPA bots

  • Connection with Power Automate Online for cloud orchestration

In short, PAD lets your PC behave like a virtual assistant — performing repetitive manual actions on your behalf.

What Is Power Automate Online?

Power Automate Online, sometimes called Power Automate Cloud Flows, is the web-based automation service accessible via the Power Automate portal (flow.microsoft.com). It focuses on cloud-based workflow automation between online services such as:

  • Microsoft 365 (Outlook, SharePoint, Teams)

  • Dynamics 365

  • Power BI

  • OneDrive

  • Google services, Twitter, Dropbox, Slack, and hundreds of others

These workflows don’t rely on your local machine — they run in Microsoft’s cloud automatically once triggered.

For instance, you can:

  • Automatically save email attachments from Outlook to OneDrive.

  • Post a Teams message when a new item is added to SharePoint.

  • Trigger a Power BI data refresh when a file changes.

  • Send notifications to your phone when an important email arrives.

Key features of Power Automate Online:

  • Cloud-first design (no local dependencies)

  • Event-driven triggers and actions

  • Hundreds of built-in connectors (Microsoft and third-party)

  • Runs automatically 24/7 in the cloud

  • Integration with Power Platform and Azure services

  • AI Builder integration for intelligent automation

Essentially, Power Automate Online handles business process automation in the cloud, while PAD focuses on desktop-level automation.

Major Differences Between Power Automate Desktop and Online

Let’s break down their main differences in key categories.

CategoryPower Automate DesktopPower Automate Online
EnvironmentRuns locally on Windows machinesRuns entirely in Microsoft Cloud
Type of AutomationRobotic Process Automation (RPA)Cloud-based Workflow Automation
ConnectivityWorks with local files, desktop apps, browsersConnects to online services via APIs
ExecutionAttended (manual start) or unattended (via agent)Automatic triggers (scheduled, event-driven)
User InterfaceWindows desktop app (drag-and-drop designer)Web interface (flow.microsoft.com)
IntegrationConnects to Power Automate Online for orchestrationCan trigger or monitor PAD flows
LicensingFree with Windows 10/11 for attended use; paid for unattendedRequires Microsoft 365 or Power Automate subscription
Best ForAutomating local/legacy desktop tasksAutomating cloud-based workflows

In short:

  • PAD = Desktop automation

  • Online = Cloud automation

They’re complementary — not competitors. Many organizations use both together for end-to-end automation (cloud triggers launching desktop flows).

When to Use Power Automate Desktop

You should use Power Automate Desktop if your workflows involve:

  • Repetitive manual tasks performed on a Windows computer.

  • Applications without APIs (legacy desktop apps).

  • File operations (Excel, PDF, text, folders).

  • Web scraping or browser-based form filling.

  • Data migration between local and online systems.

For example, a finance team could use PAD to open invoices, extract data, and update Excel reports automatically every morning.

Advantages:

  • Works with any desktop software, even without APIs.

  • Simple recording and drag-and-drop design.

  • Can run on-premises or virtual desktops.

  • Integrates with Power Automate Online for centralized control.

Limitations:

  • Requires local execution (machine must be online).

  • Resource-heavy for long unattended runs.

  • Limited scalability compared to cloud automation.

When to Use Power Automate Online

You should use Power Automate Online if your tasks are cloud-based or data-centric, such as:

  • Integrating Microsoft 365 apps.

  • Automating notifications and email flows.

  • Syncing files between services (OneDrive, Dropbox).

  • Triggering workflows based on database or API events.

For instance, you can create a flow: “When a file is uploaded to SharePoint, send a Teams message and start a PAD desktop process to process it.”

Advantages:

  • Always available; no need for a local PC.

  • Scalable and secure (Azure cloud infrastructure).

  • Integrates with hundreds of online connectors.

  • Event-driven automation that runs instantly.

Limitations:

  • Cannot directly interact with desktop interfaces.

  • Some advanced connectors require premium licenses.

  • Internet connection required for all operations.

Integration: Power Automate Desktop + Online Together

The real power emerges when you combine both versions.

Power Automate Online can trigger a Desktop Flow on a registered machine. For example:

  1. A cloud flow detects a new email attachment in Outlook.

  2. It sends the file to a virtual machine where Power Automate Desktop is installed.

  3. PAD opens the file, processes it using a local application, and sends the results back to the cloud.

This hybrid approach bridges the cloud and local environments, creating true end-to-end automation — especially useful for enterprises running both modern cloud apps and older desktop systems.

Licensing and Cost Considerations

As of 2025, Microsoft offers the following structure:

  • Power Automate Desktop (Attended): Free with Windows 10 and 11.

  • Power Automate Desktop (Unattended): Requires paid RPA license (Power Automate per-user with attended RPA or per-flow plan).

  • Power Automate Online (Cloud Flows): Included in most Microsoft 365 subscriptions, but some premium connectors (e.g., Salesforce, Dataverse, SAP) require higher-tier licenses.

When planning your automation strategy, review which version aligns with your environment and licensing budget.

Security and Governance

Both versions comply with Microsoft’s enterprise security standards, but the governance models differ:

  • Power Automate Online: Uses Azure AD authentication, DLP policies, and environment-level controls.

  • Power Automate Desktop: Uses Windows authentication and machine group management; must ensure the host computer is secure.

Organizations can manage both through the Power Platform Admin Center, defining policies for flow sharing, permissions, and data protection.

Choosing Between Power Automate Desktop and Online

Here’s a quick guide:

If you need to…Choose
Automate tasks on a local computerPower Automate Desktop
Integrate cloud apps and servicesPower Automate Online
Run UI automation on legacy systemsPower Automate Desktop
Send notifications, sync files, manage dataPower Automate Online
Combine cloud triggers with local actionsBoth (hybrid)

In many real-world scenarios, using both together yields the most value. Cloud flows manage triggers, scheduling, and API-level automation, while desktop flows handle the physical execution of tasks on local or virtual machines.

Conclusion

Power Automate Desktop vs Online While Power Automate Desktop and Power Automate Online are part of the same Microsoft ecosystem, they address different automation needs. PAD specializes in desktop-level robotic automation, while Power Automate Online focuses on cloud-based process automation.

For individuals automating local, repetitive tasks — PAD is ideal. For organizations integrating cloud systems — Power Automate Online delivers broader scalability. And for those seeking true end-to-end automation across both worlds, using both together is the smartest approach.

Ultimately, your choice depends on where your tasks live — on the desktop or in the cloud. With Power Automate, you don’t have to choose just one — you can seamlessly connect them and build a complete, intelligent automation ecosystem that drives productivity across your entire digital workspace.
