bootstack

From idea to a shipped desktop app — fast.

bootstack gives engineers, data scientists, and hobbyists everything to build a polished desktop interface and package it into a standalone executable — declarative, reactive, and batteries-included, all in pure Python.

Why bootstack

Declarative and reactive

Your code mirrors the interface — nested with blocks are the layout — and state bound once flows to every widget that uses it. No geometry math, no manual wiring.

Batteries included

60+ themed widgets — tables, trees, calendars, a syntax-highlighting code editor, forms with validation, and data sources — plus icons and localization. The pieces of a real application, already built.

Looks right by default

Semantic styling — accent="primary", variant="outline" — instead of hand-picked colors, so the same code looks correct across eight light/dark themes and switches at runtime.

Ready to ship

Lightweight to install with no heavy runtime, and a CLI that scaffolds, runs, and packages your project into a standalone executable.

A glimpse

A complete window is a handful of lines — the structure you read is the structure you get:

import bootstack as bs

with bs.App(title="Hello", padding=16, gap=16) as app:
    bs.Label("Hello from bootstack!")
    bs.Button("Primary", accent="primary")
    bs.Button("Success", accent="success")
    bs.Button("Danger Outline", accent="danger", variant="outline")

app.run()
