Thank you! The UI framework is entirely built in house with the help of Nathan Sobo (co-founder of the Atom text editor). We definitely considered a few of the options on https://www.areweguiyet.com/ but ultimately found none of them supported the requirements we wanted.

You can find more details about why we decided to build our own UI framework in the "How Warp Works" blog post we wrote here: https://blog.warp.dev/how-warp-works/
