Shadowrocket is a rule-based proxy utility that captures all HTTP, HTTPS, DNS, and TCP traffic from any app and redirects it to a proxy server, then records and displays each request for detailed inspection. Users define rules by domain match, suffix, keyword, CIDR IP range, or GeoIP lookup, import configurations via URL or iCloud Drive, and measure usage and speed across Wi-Fi, cellular, direct, and proxy connections. It also blocks ads by domain or user-agent rules, supports local DNS mapping, decrypts HTTPS traffic, rewrites URLs, and fully supports IPv6. Advanced script filters, multi-level forward proxying, and compatibility with kcptun, cloak, gost, and v2ray plugins extend its flexibility, while DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC ensure secure name resolution. Shadowrocket runs seamlessly on cellular networks and integrates SSH tunneling with UDP gateway support, making it a powerful tool for monitoring, filtering, and optimizing network traffic.
