cfnew is a V2Ray subscription management system and network proxy orchestrator designed to route traffic across multiple protocols, including VLESS, Trojan, and xhttp. It functions as a latency testing tool and a web-based proxy controller for managing node configurations and preferred IP addresses.
The project features a subscription format converter that uses user-agent detection to deliver network configurations in formats compatible with specific client applications. It also provides a web-based configuration interface backed by a key-value store for updating system settings and routing rules without redeploying code.
The system manages traffic steering through multi-protocol routing, proxy IP overrides, and manual worker region selection. It further incorporates network performance monitoring via concurrent latency testing and secures connections using DNS-over-HTTPS for encrypted TLS handshakes.
