Versions

Playwright Version: 0.152.0 Windows Version: WSL: Version 2 vscode: 1.50.1

I see what you are saying. So you’d like a mode where your project along with the tooling is in WSL, but the browser opens in the host system. Let us collect more feedback on it.

[pavelfeldman]

Oh, you can’t run headful on WSL - there is no display. (headless=False) won’t work on headless systems such as WSL.
