Well, Cypress is going to use playwright for their Webkit integration.

Cypress is more limited compared to Playwright such as multi-domains aren't supported, multiple tabs, or popup windows. For my tests that require that I am using Playwright and for the rest I am currently using Cypress. But I do think the test writing experience is better with Cypress :)

I am considering to move to Playwright for everything now with the new Trace Viewer (https://playwright.dev/docs/debug#playwright-trace-viewer); and contribute to that.
