Here's an open source alternative (actually a huge improvement to how most people do frontend tests) I put together a while back: https://github.com/testfront-io/testfront-devtools (See also https://www.testfront.io/ for an actual description of how it works, but don't bother signing up.)

I'm really bad at marketing/getting the word out, and google took forever to approve the extension so I lost interest. I made it because I hate manually writing E2E tests like with Cypress.

Maybe if others show interest in it, I'll be motivated to resume the plans I had for it.
