UiPath (#1, 9.3/9.4). The most complete enterprise RPA platform. It also handles AI-powered document processing.

Best for Microsoft 365 workflow automation

Microsoft Power Automate (#2, 9.1/9.4). Lowest-friction RPA inside Microsoft 365. It also handles Low-cost attended bots.

Best for Cloud-native unattended automation

Automation Anywhere (#3, 9.0/9.4). The strongest fully cloud-native RPA suite. It also handles Web-based bot building.

Best for ERP-embedded process automation

SAP Build Process Automation (#5, 8.4/9.4). Best RPA for SAP-heavy estates. It also handles SAP-centric workflows.

Best for Code-first Python automation

Robocorp (Sema4.ai) (#11, unrated wildcard). Open-source, developer-owned RPA. It also handles Developer-owned open-source bots.

What is RPA software and what problem does it solve?

RPA software builds software robots that mimic how a person clicks, types, and moves data between applications, so repetitive rules-based work runs without human effort. The problem it solves is swivel-chair labor: staff copying data between an ERP, a spreadsheet, and a web portal for hours. A bot does the same steps in minutes, around the clock, without transcription errors, which frees people for judgment work and cuts cycle time on tasks like invoice processing and account setup.

What is the difference between attended and unattended RPA?

Attended bots run on a person's desktop and are triggered by that user during their work, which suits call centers and front-office tasks where a human stays in the loop. Unattended bots run on servers or virtual machines with no person present, triggered by a schedule or a queue, and are managed by an orchestrator. Most enterprise programs use both: attended bots to assist employees and unattended bots to run high-volume back-office processes overnight.

How to choose

1. 1First, match the platform to your existing stack. If you run Microsoft 365 and Azure, Power Automate gives the lowest friction and cost, while Salesforce-heavy or SAP-heavy shops get more value from platforms with deep connectors into those systems.
2. 2Next, weigh developer model against citizen-developer reach. UiPath and Automation Anywhere suit a formal CoE with trained developers, while Power Automate and low-code tools let business analysts build attended bots with less training.
3. 3Finally, judge the AI layer, not just the recorder. The gap between vendors now sits in document understanding and agentic AI, so pilot each tool on your messiest unstructured inputs like invoices or claims before committing to a multi-year license.

What is the best RPA software?

The best RPA software for most large enterprises is UiPath, because it pairs a mature developer studio and orchestrator with document processing and AI agents on one platform. Microsoft Power Automate is the best value for organizations already on Microsoft 365, and Automation Anywhere is the strongest fully cloud-native alternative for teams that want browser-based bot building.

How much does RPA software cost?

Entry pricing varies widely. Microsoft Power Automate starts around $15 per user per month for cloud flows, with attended and unattended add-ons on top. Enterprise platforms like UiPath and Automation Anywhere are quoted annually and commonly reach six figures once you count orchestrator, unattended bot runtimes, AI features, and center-of-excellence staffing. Total cost of ownership is driven more by bot maintenance than by license price.

Is Microsoft Power Automate real RPA?

Yes. Power Automate includes Power Automate Desktop for attended and unattended UI automation, which is true RPA, alongside cloud flows for API-based workflow automation. For Microsoft 365 customers it is often the most cost-effective entry point. Its limits show up in large unattended fleets and advanced orchestration, where dedicated platforms like UiPath and Automation Anywhere still lead on scale and governance.

How is RPA different from AI agents?

Traditional RPA follows fixed, deterministic rules and breaks when a screen or field changes. AI agents use models to reason, read unstructured content, and adapt to variation. The two now converge: UiPath, Automation Anywhere, and Microsoft all ship agentic features that let a large language model decide steps while RPA bots execute reliable actions in legacy systems the AI cannot call directly through an API.

Do I need RPA if my systems have APIs?

If every system you touch has a clean, stable API, an integration platform or custom code is often a better, more maintainable choice than screen-scraping RPA. RPA earns its place with legacy desktop applications, mainframes, and third-party portals that expose no API, where mimicking the user interface is the only automation path. Many teams combine API integration for modern apps with RPA for the legacy long tail.
