#Managing browser binaries
Each version of Playwright needs specific versions of browser binaries to operate. By default Playwright downloads Chromium, WebKit and Firefox browsers into the OS-specific cache folders:

#Download from artifact repository
By default, Playwright downloads browsers from Microsoft and Google public CDNs.

In certain cases, it is desired to avoid browser downloads altogether because browser binaries are managed separately.
This can be done by setting

#Download single browser binary
Playwright downloads Chromium, Firefox and WebKit browsers by default. To install a specific browser, pass it as an argument during installation.
