This is built on top of Blitz (https://github.com/dioxuslabs/blitz): a new modular (open source) browser engine that I've been building for the last 2.5 years.
(I wasn't involved in building kitesurf, but I am informed that they intend to open source and upstream their patches)
any plans to support webdriver bidi for automation? (i'd be happy to help!)
[edit: for others reading who don't usually nerd out on browser automation protocols: webdriver bidi is the new-ish w3c cross-browser standard inspired by CDP - the main magic was the upgrade to websockets and also to standardize the capture of network-level traffic. there are still feature gaps between CDP and BiDi (in spec and implementation), but long term, i believe we should bet on web standards, not proprietary protocols controlled by one company.
(disclosure: i started the selenium and appium projects.)]
