Playwright is a new alternative to Selenium, and besides being cross-browser, is focused on performance, developer ergonomics and reliability (death to flakiness!). Might be worth checking out? https://github.com/microsoft/playwright . Disclaimer: I work with the Playwright team at Microsoft.
Keen to check it out; the flakiness of Webdriver/Selenium I often wonder is more pain than it brings. So many sites I see disabling tests based on it because they sometimes work/sometimes don't, the hours that get plowed into it. Edit: Missed the Microsoft ref. Not so keen.
The team is working very hard to be open/transparent/available (https://github.com/microsoft/playwright), and we’re very excited to build a better automation stack with the help of the community. I only ask since I’d love to hear any feedback for how we could improve the way we run/position the project. Thanks!
