BTOP++
BTOP++ for Windows
BTOP++ is the Windows port of btop++, bringing the same modern, graphical terminal resource monitor experience to Windows systems. It shows detailed and live statistics for processor usage, memory consumption, disk activity, network traffic, and both processes and services, all in an interactive terminal UI. The project is implemented as a native Windows build of the C++ btop++ continuation of bashtop and bpytop, optimized for Windows consoles. It relies on ANSI escape sequences for its rich graphical interface; as a result, it needs at least Windows 10 version 1607 for proper support in the standard CMD terminal or a custom terminal emulator with ANSI support. The README highlights practical notes such as recommended fonts that include braille symbols (for nicer graphs) and suggests Windows Terminal for users who want the best experience on older versions. -
