flux is a TUI process manager focused on quickly finding, monitoring, and killing processes without the visual clutter of tools like htop or btop. It adds port discovery so you can immediately see which process owns a given port.

Features

  • Real-time CPU, memory, and disk usage per process
  • Port-aware process listing — see which ports each process is listening on
  • Batch kill by selection (Space) or filter pattern (--nuke)
  • Choose termination signal (SIGTERM, SIGKILL, etc.)
  • Sort by CPU, memory, PID, name, or disk
  • Context-aware coloring highlights high resource consumers
  • Keyboard navigation with j/k or arrow keys
