It's great to see some more competitors on the TUI front of the Python ecosystem! I recently tried multiple existing frameworks and was not particularly happy with the state.
Here are the main contenders for libraries that provide higher-level API than urwid/ncurses:
* Picotui, https://github.com/pfalcon/picotui
* Npyscreen, https://github.com/npcole/npyscreen
* py_cui, https://github.com/jwlodek/py_cui
Both Picotui and Npyscreen are relatively unmaintained / considered feature-full. py_cui seems to be in the best shape.
Fingers crossed for this project making it through, building on top of Rich gives it quite a bit of headstart. You can also sponsor @willmcgugan on Github [0].
