Karing

🚀 Karing — Simple & Powerful Proxy Utility

Karing is a modern cross-platform proxy utility built with Flutter and powered by a modified sing-box core. It brings together support for multiple proxy and subscription formats, flexible routing rules, node groups, configuration synchronization, and a beginner-friendly interface in a single application.

🔌 Broad Configuration Compatibility

Karing works with Clash, V2Ray/V2Fly, sing-box, Shadowsocks, subscription links, and GitHub-based subscriptions. It provides full support for standard Clash configurations and partial support for Clash.Meta configurations, making it suitable for users with different existing configuration sources.

🧩 Smart Subscription & Node Management

Multiple subscription sources can be managed together and processed through routing rules. Karing can automatically apply configured rules to available sources and help select suitable nodes. Custom node groups can also be created for more control over how connections are organized.

🛣️ Flexible Routing Rules

Build your connection behavior around custom routing rule groups or use the built-in rule sets. Karing includes GeoIP, GeoSite, ACL, and other routing data, while also providing ready-to-use default rule groups designed to make configuration easier for new users.

⚙️ Beginner Mode

Not every user needs to manually configure advanced networking options. Karing includes a beginner mode with simplified configuration, providing a more approachable starting point while retaining advanced routing capabilities for experienced users.

☁️ Backup & Synchronization

Keep configurations available across multiple devices with built-in synchronization options. Depending on the platform, Karing supports iCloud synchronization, local network synchronization, WebDAV, and ZIP-based configuration import/export.

💻 Cross-Platform Design

Karing is designed as a multi-platform application rather than an Android-only client. Current supported platforms include Android, iOS, macOS, Windows, Linux, and tvOS, with platform-specific requirements depending on the build.

🎨 Modern Flutter Interface

The application uses Flutter for its graphical interface, providing a consistent experience across supported platforms while integrating with the underlying sing-box networking core.
