A Flutter GUI for the sing-box kernel. One set of routing rule groups distributes traffic across every node.

Key Features

• Multi-protocol: full Clash, partial Clash Meta, V2ray/V2fly, Shadowsocks, subscription formats
• Routing rule groups: customizable routing and node groups; built-in geo-IP, geo-site, ACL and karing-ruleset rulesets
• Beginner mode: simpler configuration for new users
• Multi-device sync: iCloud (iOS / macOS), LAN, WebDAV, ZIP import/export
• Author-modified sing-box core: KaringX/sing-box
• 20+ README translations: English, Traditional Chinese, Japanese, Korean, Spanish, French, German…

Target Audience

• Users needing a native sing-box proxy GUI
• People with multiple devices needing a unified proxy configuration
• Clash Meta users wanting to switch to a Flutter client

Quick Start

1. Download from the appropriate store or Releases: iOS/tvOS App Store (search "karing vpn"); Android from karing.app/download or GitHub; desktop brew install karing
2. Import a subscription or config: Home → Add → paste link or pick file
3. Pick a node → tap start
4. Multi-device sync: Settings → Sync → pick iCloud / LAN / WebDAV

Core Advantages

• Direct sing-box kernel: not a Clash-compatibility layer — drives sing-box directly
• One rule set across devices: node groups and routing rule groups stay unified everywhere
• iCloud sync out of the box: most convenient on iOS / macOS
