Several years ago, I worked at an enterprise software company that partnered with plotly and we had to use Dash to build a Tableau-like drag and drop dashboard builder.

Dash had some amazing ideas and architecture, but suffered from too little hardcore developers working on the repo. Pynecone looks a whole lot like it was heavily inspired by Dash, but re-architected with the lessons of Dash power users.

I find the project incredibly impressive and well thought out. I cringe at transpilation into Next.js, but the target code is actually extremely clean and easy to follow/read/debug. Kudos to the team.
