You can build a professional, interactive command-line application in Go by combining Cobra for command structure with Bubble Tea for terminal UI. Cobra covers argument parsing, subcommands, flag handling, and auto-generated shell completions. Bubble Tea adds spinners, tables, text inputs, progress bars, and keyboard-driven navigation on top. The result is a single statically linked binary that works in scripts and CI pipelines when called non-interactively, and provides a full terminal interface when a human runs it directly.
