### Stale browser removal ### Stale browser removal
Playwright keeps track of the clients that use its browsers. When there are no more clients that require a particular version of the browser, that version is deleted from the system. That way you can safely use Playwright instances of different versions and at the same time, you don't waste disk space for the browsers that are no longer in use.
