This is a web scraping and browser automation library characterized by its ability to write crawlers that are not easily detected (blocked/ban). It offers a robust proxy pool feature that can switch and remove invalid IPs automatically based on actual traffic, supports headless browser, simulated browser, and TLS fingerprint behaviors, as well as JavaScript rendering, screen capture, and browser automation features such as Puppeteer. In addition to the NPM package, there is also the latest open-source Python library.
