Show HN: Diggy – a reactive Python notebook in the browser

I wanted to build an experimentation platform that you can bring everywhere the web goes, i.e. a URL that you can share with anyone to start playing with a Python environment. It doesn’t matter whether it’s loaded on desktop or mobile.

My story, simply put, is frustration with Jupyter notebooks. I wanted something much easier to work with, i.e. load a small dataset, run a function and visualize results. An environment where I can manipulate code & data and immediately see feedback.

I was motivated to create an environment that:

* runs a reactive Python, cells are not executed top-to-bottom, but topologically; therefore there’s no hidden state, i.e. whenever you change a variable, all cells that depend on that variable will be automatically recalculated

* runs entirely in the browser: a) there’s zero provisioning & setup b) rich visualization libraries

* stores notebooks as plaintext files, as little metadata as possible, I do want my research to be versioned in the most native format

* empowers the experiments and exploration

* ultimately, has a (subjectively) friendly UI

It’s an early alpha version, but I am happy to answer any questions. Thank you!
