Environment Variables

NOTE playwright-core does not respect environment variables.

Playwright looks for certain environment variables to aid its operations. If Playwright doesn’t find them in the environment, a lowercased variant of these variables will be used from the npm config.

• PLAYWRIGHT_DOWNLOAD_HOST - overwrite URL prefix that is used to download browsers. Note: this includes protocol and might even include path prefix. By default, Playwright uses https://storage.googleapis.com to download Chromium and https://playwright.azureedge.net to download Webkit & Firefox. You can also use browser-specific download hosts that superceed the PLAYWRIGHT_DOWNLOAD_HOST variable:
  • PLAYWRIGHT_CHROMIUM_DOWNLOAD_HOST - host to specify Chromium downloads
  • PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST - host to specify Firefox downloads
  • PLAYWRIGHT_WEBKIT_DOWNLOAD_HOST - host to specify Webkit downloads
• PLAYWRIGHT_BROWSERS_PATH - specify a shared folder that playwright will use to download browsers and to look for browsers when launching browser instances.
• PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD - set to non-empty value to skip browser downloads altogether.
