In earlier life, I authored this exact product (including distributed deploy) for a large investment bank and a fintech startup :)
This is immensely valuable to a lot of Python devs, especially in finance/quant community. Great work!
Edit: The reason why this is so impactful is b/c most users have no idea how to build a react app (along with the circus of build/deploy train one typically entails). They just want a quick-and-dirty UI for their Python model they developed in Jupyter or similar. If the model has legs, a separate FE dev would build a fancier front end later.
