What is SFW?
Short answer
SFW is the official sing-box client for Windows. Install it only from the Vinipuch download page: the x64 installer from the download page. The five letters SFI, SFA, SFW, SFM and SFL are platforms, not five free slots. The device limit is on the plan card. Third-party shells are not recommended.
