Hello HN,

I'm releasing Hyperdiv (https://hyperdiv.io), a framework for rapidly developing reactive browser UIs in Python, with immediate-mode syntax and using Shoelace (https://shoelace.style) as its built-in component system.

This short coding video will give you a good idea of what it is: https://www.youtube.com/watch?v=4XJKfxaqvGE

I wrote a brief article about the motivation and approach: https://hyperdiv.io/intro.html

Hyperdiv doesn't aim to compete with serious full-stack frameworks. The core aim was to make it easy and fast to prototype apps and build UI-based tools. I was originally motivated by internal tools at work -- feeling the need to quickly put together UI-based tools to share with both technical and non-technical coworkers, without having to stand up and maintain a full internal stack.

This is my first major open source release. I really appreciate your feedback and support. - Marius

Looks cool. How do you see this differing from streamlit? https://streamlit.io/

looks neat. it would help if you hosted the demo apps rather than expecting the user to install and run them themselves to get a feel for it

  server-driven ui with python/vue.js

this is cool, and a way better executed/more fully featured version of this poc i did a couple weeks ago :) which uses vue under the hood

example app: https://github.com/thejchap/pue/blob/main/example.py

good luck! i think there’s definitely something here with this kind of thing

Thanks! Pue looks cool, thanks for sharing. I see some similarities to https://reflex.dev in terms of providing a declarative dom expression language with built-in conditionals and loop primitives.

  Build better UIs faster.

  

This looks really nice! I feel like Python's frontend ecosystem is currently exploding. I came across fastUI[1] today as well which looks similar.

Looks super cool! Clearly an idea that people want - I built something similar to this almost two year ago [1] but your project is a lot more fleshed out. I like that you actually used websockets instead of my hacky approach of using an http stream.

  Create web-based user interfaces with Python. The nice way.

  

Dash is similar in spirit, as a "build web UIs with Python" framework. Dash seems more similar to nicegui (https://nicegui.io) architecturally than to Hyperdiv. Like nicegui, it builds a static dom that is then mutated via callbacks or data bindings.

By contrast, Hyperdiv lays out UI declaratively based on state, and when state changes, the app re-runs, generating an updated UI. Streamlit and Hyperdiv seem to work similarly, though I'm not sure how Streamlit handles state and state-based layout.
