The Best Web Agents: Computer Use vs Operator vs Browser Use
Yusuf Ishola· March 11, 2025The relentless hype around AI agents has given birth to some rather remarkable tools.
These so-called "browser automation" agents can interact with digital interfaces just like humans—clicking buttons, filling forms, navigating websites, and manipulating applications—representing a major leap forward for automation.
In this comparison, we'll examine the best ones: Anthropic's Computer Use, OpenAI's Operator, and Browser Use and help you decide which one to use.

Benchmark Performance
Comparing the leading web agents, Claude Computer Use and OpenAI Operator, the benchmarks indicate that while Operator currently leads in web navigation tasks, Anthropic's Computer Use demonstrates superior performance in coding and software development tasks.
However, Browser Use is a more recent entrant to the market, showing promising results that surpass the Operator in WebVoyager, according to its Technical Report. It has not yet been tested on the other benchmarks.
| Browser Use | Computer Use | Operator | |
|---|---|---|---|
| WebVoyager Tests web agent accuracy on diverse web tasks | ⭐️ 89% | 56% | 87% |
| OSWorld Evaluates ability to use computer operating systems | - | 22% | 38.1% |

How Browser Use Works
Browser Use is an open-source framework that creates a bridge between LLMs and browsers. It's designed with flexibility in mind, supporting multiple models and customization options.
Browser Use works by:
- Converting screenshots to text and HTML data
- Feeding this data to an LLM for decision-making
- Executing the LLM's commands through a browser automation layer
- Repeating until the task is complete
How Claude Computer Use Works
Anthropic's Computer Use gives Claude the ability to control computers by "looking" at the screen and performing actions with virtual keyboard and mouse inputs.
Here's how it works:
- Takes screenshots of the entire desktop
- Claude analyzes the visual information
- Makes decisions on what actions to take
- Reports back with results after executing the actions
How OpenAI Operator Works
OpenAI's Operator is powered by their Computer-Using Agent (CUA) model. It's designed as a standalone agent that runs in its own browser.
The Operator workflow:
- User requests a task via the Operator interface
- Operator launches its own browser instance
- The CUA model controls this browser to complete tasks
- User can intervene at critical points (takeover mode)

💡 Key Insights
Browser Use stands out for flexibility in model choice and customization options, Operator provides the best user experience, while Computer Use offers the deepest visual understanding.
Pricing and Accessibility
| Browser Use | Computer Use | Operator | |
|---|---|---|---|
| Pricing Model | Open Source + Cloud API | API Only | Subscription |
| Cost Details | • Free to self-host • Cloud API: $0.05 per step | • Input: $3.00 per million tokens • Output: $15.00 per million tokens | • Requires $200/month OpenAI Pro subscription |
| Accessibility | Available to anyone via GitHub or cloud API | Available to developers via API | Limited to US Pro users initially |
OpenAI has stated that it plans to expose CUA in the API soon so that developers can use it to build their own computer-using agents.
What Real Users Are Saying
While benchmarks provide a standardized comparison, real-world user experiences offer much more valuable insights into how these tools actually perform in practice.
Here's a summary of these tools' real-world performance based on reviews across the internet and our own experience:
Common themes from user feedback
| Aspect | User Observations |
|---|---|
| Reliability | All tools still have occasional failures with complex interfaces. Browser Use appears most reliable for web-specific tasks, while Operator has stronger error recovery. |
| Cost vs. Value | Browser Use offers the best value for developers (free self-hosted option). Computer Use's token-based pricing can become expensive for frequent use. Operator's subscription model works well for regular users. |
| Learning Curve | Browser Use requires the most technical knowledge but offers the greatest flexibility. Operator has the simplest user experience. Computer Use falls somewhere in the middle. |
| Practical Limitations | All tools struggle with CAPTCHAs, some dynamic content, and highly complex workflows. Users often need to intervene for sensitive operations. |
Developer Experience
The developer experience differs significantly across platforms:
| Platform | Developer Experience |
|---|---|
| Browser Use | - Highly customizable with extensive integration options - Supports any LangChain-compatible LLM - Allows custom functions and callbacks - Configurable browser behavior and agent processing of visual/HTML data |
| Computer Use | - Focuses on simplicity but lacks customization - Requires Claude 3.5 Sonnet - Limited to API integration with fixed behavior - No support for custom actions |
| Operator | - Prioritizes user experience over developer flexibility - No direct API (coming soon) - Limited customization options - Strong emphasis on safety and user control - Simple web interface |
Safety Considerations
All three platforms implement safety measures, but with different approaches:
| Platform | Safety Considerations |
|---|---|
| Browser Use | - Open framework; safety is largely developer-dependent - Supports restricting operations to specific domains - Allows integration of custom middleware for additional security checks |
| Computer Use | - Implements built-in safety classifiers - Employs automatic monitoring to prevent misuse - Usage is restricted to approved cases |
| Operator | - Features a three-layer safety system: • User control via takeover mode • Data privacy controls • Defenses against adversarial websites - Monitors for suspicious behavior |
So Which Browser Automation Tool Should You Choose?
Choose Browser Use if:
- You need maximum flexibility and customization
- You want to self-host or use multiple AI models
- Developer experience and extensibility are priorities
- Cost-efficiency is important
Choose Computer Use if:
- You need to control desktop applications beyond browsers
- Visual understanding of interfaces is critical
- You need robust safety features
Choose Operator if:
- You want a simple, user-friendly experience
- You need strong built-in safety features
- You're already an OpenAI Pro subscriber ($200/month)

Frequently Asked Questions
Can these tools access my personal accounts and data?
Yes, if you authorize them. All three systems can log into websites, but they handle credentials differently. Browser Use can use your real browser profile with existing logins. Computer Use requires explicit credential input. Operator has a 'takeover mode' for sensitive information.
What happens if these tools make a mistake?
Each handles errors differently: Browser Use provides detailed logs and screenshots for debugging. Computer Use is more likely to ask for human intervention. Operator has built-in monitoring and confirmation steps.
Which is most cost-effective?
Browser Use. The self-hosted option costs only your compute resources, and even the cloud version's per-step pricing typically works out cheaper than token-based billing for complex tasks.
Which is best for developers?
Browser Use, hands down. The open-source nature, extensive customization options, and support for multiple LLMs make it the clear winner if you're writing code. The fact that you can self-host means no API rate limits or unexpected price increases.
