Carapace is a Go library and binary for generating command argument completions across many shells, including Bash, Zsh, Fish, PowerShell, Nushell, Elvish, Xonsh, and more. It integrates tightly with the Cobra CLI framework and also supports custom specs and bridging other completion frameworks.

Use cases

• add tab completion to a cobra CLI for bash and zsh
• generate shell completions for multiple shells from one spec
• write custom completion specs for existing commands
• bridge completions from other frameworks
• add completions for nushell and elvish

When to choose

• you build Go CLIs with cobra and want rich multi-shell completions
• you need one completion definition that works across many shells
• you want to add completions for commands you don't control via custom specs

When to avoid

• your CLI is not written in Go and you don't want to ship a completion binary
• you only need a single shell and prefer that shell's native completion system
• you need Cmd, Ion, or Tcsh support, which are still experimental
