SFM

The software provides a standalone graphical client for sing‑box, a universal proxy platform supporting a wide range of proxy protocols, DNS configurations, and transport options. It runs on macOS and offers users a native interface to manage inbound and outbound proxy services, configure DNS rules, set up route rules, and adjust advanced features such as multiplexing and transport settings. The client is intended for individuals who need a dedicated, easy‑to‑use front end for sing‑box without relying on command‑line tools.

It exposes the same capabilities documented in the sing‑box wiki, including support for V2Ray, UDP‑over‑TCP, TCP, Wi‑Fi state handling, and various experimental options. Users can import and edit configuration files, control proxy behavior, and monitor connection status directly from the macOS environment. The application is released under the GNU GPL v3, ensuring it can be freely redistributed and modified while preserving the original licensing terms.
