Starship

Starship is an open-source prompt for any shell, written in Rust and maintained by a community of contributors under the starship GitHub organization. Where a traditional prompt is either plain or a slow tangle of shell functions, Starship renders context modules in compiled code: the current directory, Git branch and status, language runtime versions (Node, Python, Rust, Go, and dozens more), cloud and Kubernetes context, Docker context, and command duration all appear automatically, and only when they are relevant to the directory you are in.

Configuration is a single TOML file at ~/.config/starship.toml, and dozens of community preset themes ship on the official site, so you can go from stock to a polished prompt in minutes. Setup is one line in your shell rc, such as eval "$(starship init bash)" for Bash, with support for Zsh, Fish, PowerShell, Nushell, Elvish, Ion, Tcsh, Cmd, and Xonsh across Linux, macOS, Windows, and BSD. The project bills itself as blazing fast, which is provider-claimed; there are no published independent benchmarks, though the Rust architecture and ~60,000 GitHub stars suggest the claim is widely accepted by its users. You will want a Nerd Font installed for the icons to render.

Install the binary with the official install script (curl -sS https://starship.rs/install.sh | sh) or via your package manager (Homebrew, apt, Scoop, etc.). Then add the init line for your shell to your rc file: eval "$(starship init bash)" for Bash, eval "$(starship init zsh)" for Zsh, starship init fish | source for Fish, or the PowerShell equivalent. Optional: create ~/.config/starship.toml or drop in a preset theme.
