Congrats. Looks really cool!
I'm curious how this compares to other efforts like this such as Streamlit? I do like the fact you compile to React/Next.js as that opens up the possibility of tapping into that rich ecosystem.
Also others have mentioned, and it might not be fair, but the name Pinecone (and variations) has sorta been taken at this point by the vector DB startup since they launched first. So I'd just bite the bullet and change this before the cost of switching rises later on.
