Browser Use vs Google Project Mariner (2026)
Updated March 9, 2026
Overview
Browser Use combines an open-source AI browser agent framework, fully managed web agents, and affordable, stealthy browser infrastructure. Run agents locally or in the cloud to navigate websites, complete workflows, and extract structured data. Use the browser infrastructure independently with your own automation through CDP, Playwright, or Puppeteer, with API and SDK access for both agents and browsers.
Google Project Mariner brings agentic browsing directly into Chrome, powered by Gemini. It can understand and interact with web pages — reading content, clicking buttons, filling forms, and navigating across sites. As a native Chrome feature for AI subscribers, Project Mariner represents the shift of browser agents from standalone tools to built-in browser capabilities, leveraging Google's unmatched understanding of web structure.
