The ZenRows® Scraping Browser uses the Chrome DevTools Protocol (CDP) as its communication standard. CDP is a powerful protocol used for browser automation and debugging, allowing you to control a browser instance programmatically.

​
Why CDP?

CDP is widely adopted because it provides deep control over browser behavior, offering features like:

  • Page interaction: Automate navigation, clicks, form submissions, etc.
  • Network monitoring: Access detailed network activity, including headers, responses, and requests.
  • DOM manipulation: Direct interaction with and modification of the Document Object Model (DOM).
  • JavaScript execution: Run JavaScript code within the page context.
  • Performance tracking: Monitor performance metrics, including rendering and page load speeds.
  • Screenshots & PDFs: Capture visual representations of the page.

By leveraging CDP, the ZenRows Scraping Browser allows you to interact with web pages just like a human user would, while also benefiting from additional features like IP rotation and proxy management.

​
How is CDP different from other protocols?

Compared to other protocols like WebDriver (used by Selenium), CDP is generally faster and more capable because it communicates directly with the browser’s core without the intermediary of a WebDriver layer. This direct interaction gives CDP greater flexibility and control, making it the protocol of choice for ZenRows Scraping Browser.
