What is Browser Agent?

An AI system that controls a real web browser to browse, interact with, and complete tasks on websites.

Browser agents are AI-powered systems that control real web browsers (Chrome, Firefox, Safari) to perform tasks autonomously on behalf of users. Unlike traditional crawlers that make simple HTTP requests, browser agents click buttons, fill forms, scroll pages, and navigate complex workflows — exactly like a human would.

Examples include OpenAI Operator, Claude Computer Use, and various systems built on automation frameworks like Puppeteer, Playwright, and Selenium. Browser agents represent the most advanced form of AI-web interaction, capable of completing purchases, signing up for services, and conducting research.

The key challenge with browser agents is detection. Because they use real browsers with standard user-agent strings, traditional bot detection methods (UA filtering, robots.txt) are ineffective. Detection requires behavioral analysis: examining automation flags, interaction timing patterns, and JavaScript environment signals.

How Switch Helps

Switch detects browser agents through behavioral analysis, automation flags, and fingerprinting — methods that work even when the agent uses a standard browser UA string.
