what is flow fr?

Flow is a terminal dashboard that shows one thing clearly: how much data your network connection is sending and receiving right now. Most network monitoring tools try to show everything at once, CPU usage, memory, running processes, connection tables, and throughput all crammed together. Flow strips that away and focuses only on throughput, the speed at which data moves in and out of your machine. The display updates in real time with a smooth animated waveform, so you can watch your download and upload speeds move like a heartbeat rather than jumping in static numbers. It automatically resizes itself to fit your terminal window, offering a full detailed view when there is space and a single compact line when there is not, which makes it useful for things like a status bar in a terminal multiplexer such as tmux. Beyond the basic view, flow includes a panel that lists which programs on your computer are actively using the network, an overlay showing details about your network interface such as its IP address and hardware address, and a built in ping indicator so you can watch latency at the same time as bandwidth. It ships with eight color themes and supports custom ones written in a simple configuration format. It also tracks peak speeds and daily data totals that persist even after you close and reopen it. For people who want to pipe network data into scripts or other programs, flow can output its readings as JSON, either as a single snapshot or as a continuous stream of updates. It requires no special permissions to run and works on Linux, macOS, and Windows. Installation is available through Homebrew, the Arch Linux AUR, or by building it directly from the Go source code, and prebuilt binaries are offered for common operating systems and processor types. Configuration happens automatically on first run, creating a settings file you can edit later if you want to change defaults like refresh speed or your preferred ping target.
