Headless Browser
A browser environment that runs without a graphical interface, widely used for automated testing and web scraping. At runtime it exposes characteristics such as navigator.webdriver, missing plugins and anomalous WebGL renderers, making it easy for detection systems to identify.

Modern AI agent frameworks are mostly built on headless browsers, and their runtime exposes characteristics different from regular browsers, such as navigator.webdriver being true, a missing plugin list, and abnormal WebGL renderer strings; these environmental features become a key突破口 for defenders to identify automated traffic.
Incremental sync tools typically require headless browser rendering, waiting for network idle before extracting the DOM, and fault tolerance for render timing and lazy loading.
This solution covers only HTTP, not browsers; if an agent drives a headless browser, each page load triggers dozens of sub-requests, so the token bucket needs to be placed before navigation and clicks, with each operation counted as one action.
A headless browser launches a brand-new, unauthenticated browser environment and cannot inherit the user's cookies, session, or locally stored login state.
In actual testing, memory usage in headless mode is typically only 30–50% of that in visual mode, and page load speed is improved by 40–60%.
