## What it is
Karing is a free, cross-platform proxy utility built with Flutter that serves as a GUI for a modified sing-box core. It supports Clash, V2ray, Sing-box, and Shadowsocks subscriptions with unified routing rules, custom rule groups, and multi-device configuration sync.

## Use cases
- manage clash and sing-box subscriptions in one app
- route traffic through proxy servers with custom rules
- bypass geo-restrictions and censorship
- sync proxy configuration across multiple devices
- import v2ray and shadowsocks subscription links
- set up a proxy client on apple tv or windows

## When to choose
- you need a free cross-platform proxy GUI compatible with clash/sing-box/v2ray subscriptions
- you want one set of routing rules applied across multiple subscription sources
- you want beginner-friendly defaults with advanced customization available
- you need config sync across devices including iCloud or WebDAV

## When to avoid
- you need a headless proxy server or CLI-only tool
- you require a license-verified open-source build (license is non-standard)
- you only need a simple system proxy without subscription management
- you need Google Play distribution on Android
