it's chill, works well. way better than streamlit but out of box i'm not a huge fan of material ui in nicegui. but good lord it actually behaves like an app. events and state management via event queue between the browser are great. it just looks kinda ugly, but you can at least rapidly prototype a working web app really quickly with it. solid for office tooling.
i've moved on from python apps though, i for whatever reason just woke up one day and decided im tired of runtime dependencies and i wanted compiled binaries serving up whatever.
