Browser Automation

Browser automation is the underlying infrastructure on which every AI agent, scraper, and end-to-end test sits. The vocabulary is shared across a wide range of tools — Playwright, Puppeteer, Selenium, Stagehand, Notte — but the concepts are remarkably stable: headless versus headful execution, the Chrome DevTools Protocol, browser sessions and contexts, anti-bot detection and the fingerprinting signals it relies on, residential and datacenter proxies, parallel execution, and the boundaries between cloud, serverless, and self-hosted deployments. Understanding these primitives is the difference between an automation that works in development and one that survives production traffic and detection systems. This category collects the canonical definitions every developer touching the browser layer should know.
