## What it is
SproutCore is a JavaScript MVC framework for building fast, native-caliber single-page web applications that run in the browser. It provides a full-stack client-side approach including views, bindings, state management, and build tooling.

## Use cases
- build a single-page web application with an MVC architecture
- create desktop-like rich web apps in the browser
- manage complex UI state with bindings and observers
- build maintainable large-scale JavaScript frontends
- develop web apps with native-app feel and performance

## When to choose
- you are maintaining or extending an existing SproutCore codebase
- you want a batteries-included MVC framework with bindings for a legacy-style SPA
- your team already knows SproutCore conventions

## When to avoid
- you are starting a new project - modern frameworks like React, Vue, or Ember are better supported
- you need an actively developed ecosystem with current tooling and community
- you want a lightweight library rather than an opinionated full framework
