Cliffy is a TypeScript-first, runtime-agnostic toolkit for building complex command-line applications on Deno, Node, and Bun. It provides a command framework, argument parser, interactive prompts, table builder, ANSI escape utilities, and keypress handling.
Use cases
- build a complex CLI with subcommands and type-safe options
- parse command line arguments and flags in TypeScript
- create interactive prompts with validation and autocompletion
- render unicode tables in the terminal
- add shell completions and auto-generated help to a CLI
- handle raw keypress events in a terminal app
When to choose
- you want a TypeScript-first CLI framework that works across Deno, Node, and Bun
- you need interactive prompts, tables, and ANSI utilities from one toolkit
- you want auto-generated help, input validation, and shell completions out of the box
When to avoid
- you only need a minimal argument parser without a full framework
- you are building a GUI or web app rather than a terminal tool
- your project is not TypeScript/JavaScript based
