sistine 0.3.5

HTML builder with server routing for Python

Sistine

React-like UI framework for Python. Build reactive web UIs with HTML/Tailwind + Alpine.js, powered by Streamlit.

Sistine wraps Streamlit with a routing layer, DOM builder, and reactive client-side components — giving you pixel-perfect custom UI without giving up Python.

Why Sistine, why not Streamlit?

Streamlit is great for data apps fast, but falls short when you need:

Pain point	Streamlit	Sistine
CSS control	Limited, no hover/flexbox/grid/animations	Full Tailwind + custom CSS
Custom HTML	No ergonomic HTML builder	el.div(cls="...")(child) chaining syntax
Client interactivity	Full page reload on every interaction	Alpine.js — no reloads, reactive
Architecture	Linear script	MVC with routing (@app.sistine("/"))
API endpoints	None built-in	@app.query — JSON endpoints callable from JS
Static export	Not supported	sistine build → static HTML files

You keep Streamlit's Python ecosystem while getting frontend-level UI control.

Reactive Components

Sistine ships with Alpine-powered components that talk to your @app.query endpoints — dropdowns, tables with pagination, forms, live-updating views, and mutation buttons. No JS required.

Routing & MVC

Decorator-based routing with path params. Optional MVC scaffolding via sistine init — models, views, controllers.

Auth & Session

@alpinejs/persist is auto-included. Build login flows with client-side session persistence using $persist().

Installation

pip install sistine
