The short answer
Yes. Rebuilt or re-downloaded automatically when needed.
What is it?
Playwright downloads its own WebKit build to test Safari-like behaviour, stored in ~/Library/Caches/ms-playwright as webkit-<build> folders. Each Playwright upgrade can add a new one, and older builds may remain. Each is typically a few hundred MB.
What happens if you delete it?
Old builds come back only if a project still needs that version and you run npx playwright install. The newest build is kept.
How to remove it properly
Run npx playwright uninstall in a project to remove builds no installation still uses. Otherwise move the older webkit-* folders to the Trash in Finder (Go › Go to Folder… ~/Library/Caches/ms-playwright).
Quit the app that uses it, then move it to the Trash. Empty the Trash when you’re sure.
- MoreRoom keeps the newest 1 and suggests the older ones.
How MoreRoom helps
