## What it is
PocketJS is a portable application runtime that compiles Solid, Vue Vapor, or Octane component code into a native UI tree rendered by a no_std Rust core with QuickJS as the JS guest. It targets radically different hardware - Sony PSP, PS Vita, desktop, browser, and headless hosts - with no DOM, CSS engine, or WebView.

## Use cases
- build native UI apps for PSP and PS Vita with modern JavaScript frameworks
- write cross-platform UI components that run without a browser or WebView
- render flexbox layouts on embedded and retro hardware
- run Solid or Vue components on constrained devices
- develop UI apps with Tailwind-style classes compiled ahead of time
- test the same UI logic in browser, headless, and on-device hosts

## When to choose
- you need one component codebase running on game consoles, desktop, and browser
- you want a DOM-free, WebView-free native rendering pipeline with a Rust core
- you target retro or embedded hardware like PSP, Vita, or Windows CE devices
- you prefer Solid, Vue, or React-style component authoring for non-web targets

## When to avoid
- you need full CSS support, a real DOM, or web platform APIs
- you are building a standard website or web app where a browser is the target
- you need a mature ecosystem with extensive third-party component libraries
- you require production support for mainstream mobile platforms today
