Google Chrome Versions

BlitzBrowser supports running multiple versions of Chrome for Testing. This allows you to test your scripts against specific Chrome releases or ensure compatibility when Google introduces new browser features.

  • Versions supported: Any version listed in the Google Chrome Labs Known Good Versions can be used. Chrome 116 is the earliest supported version.
  • Storage: All downloaded browser binaries are persisted in the /blitzbrowser/browsers/... directory.

Supported Versions​

  • default: This is the default value. It will use the pre-installed Chrome for Testing in the Docker image.
  • latest: This value will install the latest version available from the Google Chrome Labs Known Good Versions.
  • xxx.x.xxxx.x: Set the specific version you want to run. It can be any version since 116.x.xxxx.x.

How it works​

By default, BlitzBrowser uses the Chrome version pre-installed in the Docker image. However, you can request a specific version via the CDP connection URL.

If the requested version is not already present in the /blitzbrowser/browsers folder, BlitzBrowser will automatically download it before connecting your client.
