RPA exists because a huge amount of enterprise software was never built with automation in mind — decades-old desktop applications, mainframe systems, internal tools with no API and no plan to ever get one. Robotic process automation solves this by essentially teaching a bot to use software the way a human does: clicking specific buttons, reading specific screen locations, typing into specific fields — which is a fundamentally different (and more fragile) approach than the API-based connections that tools like Zapier rely on.
What AI added to this category in the last few years is real: older rule-based RPA bots broke the moment a screen layout changed slightly, or failed entirely on anything unstructured like a scanned document or a handwritten form. AI-enhanced RPA handles both meaningfully better, which is the actual reason this category still matters even as more software gets modern APIs.

Quick Comparison
| Tool | Strongest at | Best for | Pricing model |
|---|---|---|---|
| UiPath | Broadest platform, largest ecosystem | Enterprises wanting the most mature, full-featured platform | Enterprise pricing, free community edition |
| Automation Anywhere | Cloud-native architecture | Organizations wanting RPA without on-premise infrastructure | Enterprise/quote-based pricing |
| Blue Prism | Governance and security controls | Highly regulated industries (finance, healthcare, government) | Enterprise/quote-based pricing |
| Nanonets | Document data extraction specifically | Automating data entry from invoices, forms, and scanned documents | Free tier + paid plans by volume |
UiPath — the broadest, most established platform
UiPath has the largest ecosystem in enterprise RPA — the most third-party integrations, the most available talent already trained on the platform, and a genuinely free community edition that lets a team evaluate it seriously before committing to an enterprise license. For an organization building out a first RPA program without a strong existing preference, UiPath's maturity and available support resources make it the safer default starting point.
- Largest talent pool of trained RPA developers, which matters when hiring or contracting for implementation
- Free community edition allows a genuine evaluation before any enterprise spend
- Broadest set of pre-built connectors and automation templates across common enterprise software
Automation Anywhere — best for a cloud-first RPA setup
Automation Anywhere built its platform cloud-native from early on, which matters for organizations that don't want to manage on-premise RPA infrastructure themselves. This cloud-first approach generally means faster initial deployment and less internal IT overhead compared to more traditionally on-premise-oriented RPA platforms, at the tradeoff of less flexibility for organizations with strict data-residency requirements that mandate on-premise processing.
Blue Prism — best for regulated industries needing strict governance
Blue Prism has built its reputation specifically around governance, security, and audit controls — features that matter disproportionately to banks, insurers, healthcare organizations, and government agencies operating under strict regulatory requirements. Where UiPath and Automation Anywhere both compete partly on ease of use and speed of deployment, Blue Prism leans harder into the compliance and control side of the equation, which is exactly what a heavily regulated organization's procurement process tends to prioritize.
In regulated industries, the audit trail matters as much as the automation itself.
Nanonets — best for a specific, narrower job: document data extraction
Not every automation need justifies a full enterprise RPA platform. Nanonets focuses specifically on one common, high-value job: extracting structured data from unstructured documents — invoices, receipts, forms, ID documents — using AI to read them accurately even when formats vary. For a company whose actual bottleneck is manual data entry from documents rather than broader legacy-system automation, Nanonets solves that specific problem faster and cheaper than standing up a full RPA program would.
- Handles varying document formats and layouts without needing a separate template per document type
- Meaningfully cheaper and faster to implement than a full enterprise RPA platform
- Narrower in scope — it's a document-processing tool, not a general legacy-system automation platform
What "AI built in" actually means for RPA specifically
- Handling unstructured input. Reading a scanned invoice or a handwritten form, which older rule-based bots simply couldn't do reliably.
- Adapting to minor UI changes. AI-enhanced bots can sometimes recognize a button or field even after a minor layout change, reducing (though not eliminating) the classic RPA maintenance headache of a bot breaking every time the underlying software gets a UI update.
- Smarter exception handling. Flagging genuinely ambiguous cases for human review instead of either failing outright or guessing incorrectly, which reduces the error rate on edge cases a purely rule-based bot would have mishandled silently.
- Faster bot-building itself. Some platforms now let a developer describe the desired process and generate a starting bot workflow from that description, similar to how no-code tools generate a first-draft automation, though the result still needs testing against the actual legacy application before going live.
Frequently Asked Questions
How is RPA different from the no-code automation tools like Zapier or Make?
No-code tools connect apps that have modern APIs. RPA automates interactions with software that doesn't — literally simulating clicks and keystrokes the way a human would use the application, which is why it's the right tool for legacy systems specifically.
Does RPA still make sense if most of our software has modern APIs now?
It depends on what's left — if a specific legacy system or two is the actual bottleneck and everything else already has API access, a narrower tool (or even Nanonets for a document-specific need) may make more sense than a full enterprise RPA program.
How long does a typical RPA implementation take?
It varies significantly by process complexity and organization size, but expect a real project timeline — weeks to months for initial processes, not a same-day setup — since RPA bots need to be built and tested against the actual legacy system's specific quirks.
Is Nanonets a real alternative to full RPA, or just a smaller add-on?
For document-specific data extraction specifically, Nanonets can genuinely replace what would otherwise require a broader RPA implementation — it's a legitimate standalone solution for that particular job, not just a supplementary tool.
How much does enterprise RPA typically cost?
Pricing for UiPath, Automation Anywhere, and Blue Prism is generally quote-based and scales with the number of bots and processes automated, plus implementation costs that often exceed the software licensing itself — budgeting for a full program rather than a simple subscription is realistic.
Who typically manages an RPA program day to day — IT, operations, or a dedicated team?
Most organizations running RPA at any real scale build a dedicated Center of Excellence — a small team that owns bot development, monitoring, and governance across the organization — rather than leaving it to whichever department first requested a bot, since RPA maintenance and oversight needs consistent ownership as the number of automated processes grows.
Final Verdict
For most organizations starting an RPA program without a strong existing preference, UiPath's maturity and ecosystem make it the safer default. Choose Automation Anywhere if avoiding on-premise infrastructure matters, and Blue Prism if you're in a heavily regulated industry where governance and audit controls are non-negotiable. If the actual need is narrower — just getting data out of documents — Nanonets solves that specific problem without the overhead of a full RPA platform. More tools live in Automation & Workflow tools.
