Go CUI Frameworks
Overview
Go, with its language design emphasizing simplicity and efficiency, is one of the best choices for CLI tool development. Features like compilation to single binaries, fast execution speed, and easy cross-compilation enable building CLI applications that are easy to distribute and highly performant. In addition to Go's standard library flag
package, a rich ecosystem of third-party libraries is available.
Major Libraries
Cobra
The most widely adopted CLI framework, used by many famous projects including Kubernetes and Docker. It provides comprehensive features including subcommands, flags, and help generation.
Urfave/cli
A CLI framework with a simple and intuitive API. It's suitable for quickly building basic CLI applications.
Kingpin
An expressive and type-safe command-line argument parser. Features a fluent API and excellent error messages.
Bubbletea
A framework for terminal UI applications, adopting a model based on the Elm Architecture. Perfect for building interactive CLI tools.
Promptui
A library that makes it easy to implement interactive prompts and selectors. Convenient for collecting and validating user input.
