Anthropic Computer Use is Claude's native ability to interact with computer interfaces by clicking, typing, scrolling, and navigating desktop and browser environments. First introduced in October 2024 with Claude 3.5 Sonnet, it has been expanded to Claude Sonnet 4.5, Sonnet 4.6, and Opus 4.6.

OpenAI Operator is an AI-powered browser agent that can autonomously navigate the web, interact with websites by typing, clicking, and scrolling, and complete complex multi-step tasks on behalf of users. Launched in early 2025 and powered by the Computer-Using Agent (CUA) model, Operator combines GPT-4o's vision capabilities with advanced reasoning through reinforcement learning to interact with graphical user interfaces. As of July 2025, Operator became fully integrated into ChatGPT as 'agent mode' and is accessible by selecting it from the dropdown in the composer.

Browser Use is an open-source automation framework that enables AI agents to control web browsers programmatically. Built specifically for agent-driven browsing workflows, Browser Use allows developers to automate complex web interactions without writing custom Selenium scripts. The platform is recognized by makers of CopyCat, Local Operator, and Web Bench as foundational for agent-driven browsing. Browser Use supports multi-modal navigation with chain-of-thought tracking and provides session GIFs for debugging. The framework can hand off browser control to AI agents that use your real browser, which is particularly helpful for automating tasks that require authentication or session management. As a relatively new automation tool, Browser Use has gained traction among developers building AI agents and automation workflows, offering a simpler and more adaptable foundation compared to traditional browser automation libraries.

Project Mariner is Google DeepMind's experimental AI browser agent that uses Gemini's powerful multimodal capabilities to autonomously navigate websites, understand screen content, plan tasks, and execute them by clicking, typing, scrolling, and filling forms. Powered by Gemini 2.0, Mariner represents a significant advancement in human-agent interaction, starting with browsers as the primary interface. The agent can parse text, images, buttons, forms, and code on web pages, allowing it to navigate complex sites much like a human would.
