## What it is
OrbTk (Orbital Widget Toolkit) is a cross-platform GUI toolkit for building user interfaces in Rust, based on the Entity Component System pattern with a functional reactive-like API. It was created to bootstrap UI development on Redox OS but has been officially sunset in favor of iced and slint.

## Use cases
- build a desktop GUI application in Rust
- create cross-platform widgets with an entity component system
- develop UI for Redox OS applications
- write a calculator or showcase app with themed widgets in Rust

## When to choose
- maintaining or contributing to legacy Redox OS applications already built with OrbTk
- studying an ECS-based Rust GUI toolkit design

## When to avoid
- starting a new Rust GUI project - use iced or slint instead
- needing a toolkit with active maintenance and modern features
- requiring long-term ecosystem support
