Why is the counter demo so slow? If you are compiling to JS/React I would expect it to be close to native perf no?
Because the logic is being processed at the backend and the data being transferred over WebSocket

#12Why should I choose this over Django or Flask? By using Python in the frontend you mean the Python is transpiled into JS? The frontend uses templating or generates a SPA app?
Yes, in Pynecone you write your frontend in Python and it's compiled to a SPA, plus a FastAPI backend server to handle state updates. Django and Flask handle the backend in Python, but you still have to use Javascript for the frontend.
SSR is included? Do you have some project that is completely build with this stack. Some real life project?

We use SSG under the hood, a good example would be our main website https://pynecone.io which is fully built in Pynecone.

#14How does Pynecone differentiate from Streamlit, Panel and Dash?
Re: Launch HN: Pynecone (YC W23) – Web Apps in Pure Python
#15I started as a backend dev, moved to full-stack and initially didn't find JS too alluring. I've since liked JS for frontend stuff (not so much backend still). I _really_ like Dash for some things but quickly find myself hitting the boundaries of it's use cases.
I will def have to check this out and keep it on my radar. I used to work for a consulting place where we would have to spin up tons of one-off apps and this seems perfect for that.

#16I've tested Pynecone recently and it's pretty good. I'm wondering how do you intend to create a business around this library.
Thanks! We're building a hosting service that you can deploy your apps to. Our plan is to have a free tier for your first app, then charge for additional apps. We're still finalizing this, so would love to hear any thoughts.
It would be nice if there was a consideration for the app being opensource for the free tier, and also integration with Github --- it would be way cool to be able to specify that a Python file on Github could be used as the source for a free app on your site.

#17Your ideas seem really cool. I'm sad that you chose a name so close to another great startup that does vector databases and search. https://www.pinecone.io/
You're headed into a place where some customers may confuse you.

#18How does Pynecone differentiate from Streamlit, Panel and Dash?
I've used some of these in the past and they're easy to get started with, but I found limitations in terms of components, styling, and performance. Since we compile down to a NextJS app, we aim to have the flexibility of traditional webdev with the ergonomics of Python

#19How does Pynecone compare to Flet? I've played with the flet framework and it seems to have a ton of potential.
