playwright got a lot of things right. one of the big ones was a fast websockets+json way to drive the browser. (vibium is using the w3c standard equivalent - webdriver bidi). but they also raised the bar on usability and developer experience. i hope to get to the level of "click, click, awesome" out-of-the-box experience that playwright did so well.
If you're already using Playwright, I'd love for you to give Stagehand a try (https://github.com/browserbase/stagehand) - it has compatible-ish API, but built for automation, not testing.
I think the future is mobile when it comes AI agents, If you are also looking for a new approach, I would suggest DeepWalker. It is mobile first automation, currently works on android.
I’m interested in checking out Vibium - I’ve been a reluctant adopter of Playwright and hopeful for a new approach.
