what is frp_client fr?

FRP Client is a native macOS app, built with SwiftUI, that gives a graphical interface for managing frp, a fast reverse proxy tool. Instead of configuring frp by hand through text files and the command line, this app lets you set up and control it visually. You can configure your frp server connection details such as address, port, authentication token, TLS, and transport protocol through the interface, and manage proxy rules covering TCP, UDP, HTTP, HTTPS, STCP, and XTCP connection types, shown as editable cards. The app includes real-time traffic charts showing upload and download speed, daily traffic totals, and connection counts, built using Apple's Swift Charts. It also shows categorized, filterable logs from the underlying frpc process, which can be exported. You can start and stop the frp connection with one click from the toolbar, and the app automatically detects and cleans up leftover frpc processes if needed. It can optionally launch automatically when your Mac starts, and can run either as a normal Dock application or tucked away in the menu bar. For users in mainland China, it includes built in GitHub mirror options to make downloading the frpc binary easier, and it automatically generates the standard frpc.toml configuration file behind the scenes. The app requires macOS 13 (Ventura) or later and runs on both Apple Silicon and Intel Macs. You can install it by downloading a prebuilt .dmg from the Releases page, though since the app is unsigned, macOS will initially block it until you clear the quarantine flag using a terminal command. Alternatively, you can build it from source by opening the Xcode project directly. The project is released under the Apache License 2.0, the same license used by the underlying frp project it wraps.
