What is cliffy?
Cliffy is a command-line toolkit for building complex CLI applications using TypeScript. It provides a suite of modular packages including a command framework, argument parser, interactive prompts, table generator, and ANSI utilities, designed to work across Deno, Node.js, and Bun runtimes. It solves the problem of creating robust, type-safe, and feature-rich command-line interfaces with consistent tooling.
Developers and teams building sophisticated command-line tools, utilities, or developer tooling who want type safety, modularity, and cross-runtime compatibility.
Developers choose Cliffy for its TypeScript-first design, runtime agnosticism, and comprehensive feature set that eliminates the need to piece together multiple CLI libraries. Its modular architecture allows using only the needed components while maintaining consistency.
