 **Q: How does Playwright relate to [Puppeteer](https://github.com/puppeteer/puppeteer)?**
 
+Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol. Puppeteer project is active and is maintained by Google.

 We are the same team that built Puppeteer. Puppeteer proved that there is a lot of interest in the new generation of ever-green, capable and reliable automation drivers. With Playwright, we'd like to take it one step further and offer the same functionality for **all** the popular rendering engines. We'd like to see Playwright vendor-neutral and shared governed.
 
 With Playwright, we are making the APIs more testing-friendly as well. We are taking the lessons learned from Puppeteer and incorporate them into the API, for example, user agent / device emulation is set up consistently on the `BrowserContext` level to enable multi-page scenarios, `click` waits for the element to be available and visible by default, there is a way to wait for network and other events, etc.
