> Karrotframe is rebranded with **"Stackflow"**. View full documentation and demo on [https://stackflow.so](https://stackflow.so/)
**Stackflow** is a project that implements Stack Navigation UX, which is mainly used in mobile devices (iOS/Android, etc.) in a JavaScript environment. So, it can help to easily develop hybrid apps and webviews.
- Stack screens and keep scrolling state.
- It supports transition effects that stack up the screen and the transition effect that disappears when you go back.
- Supports iOS-style swipe back.
- It passes the necessary parameters to the screen to be switched.
So, what advantages does **Stackflow** have compared to the existing navigation library?
- You can only use the state for stacks and transitions separately without UI. You can tear off the UI and use it as you like.
- You can inject any additional extensions you want between lifecycles through the plugin interface.
- Since the core logic and integration layers are separated, it can be integrated with various front-end frameworks. (Now only supports React)
- Because render logic and UI can be injected from the outside, mobile webview and desktop development can be done in one codebase.
- Server-Side Rendering is supported. (`ReactDOMServer.renderToString`)
## Getting Started

import { stackflow } from '@stackflow/react';
const { Stack, useFlow } = stackflow({
// ...
});
const App: React.FC = () => {
