Browser automation tools like Puppeteer and Playwright have become indispensable for developers needing to scrape data, automate tasks, or run AI agents on websites, but they face challenges with bot detection and manual management of features like proxy rotation and session persistence. Bright Data’s Agent Browser offers a stealth-focused, AI-native alternative, automatically handling aspects such as fingerprint spoofing, CAPTCHA solving, and cloud-based session management, which are crucial for interacting with sophisticated anti-bot systems on websites. While Puppeteer and Playwright are suitable for small-scale, local tasks where developers need full control over the browser environment, Agent Browser is tailored for scenarios requiring high-scale automation with minimal setup, focusing on stealth and reduced complexity. Each tool has its strengths and limitations; selecting the right one depends on the specific needs of the workflow, whether it's the ease of managing complex, multi-step tasks remotely or maintaining local control for simpler tasks.
