Oclif

Build command-line tools the Heroku way

Oclif is an open-source framework for building extensible command-line tools in TypeScript and JavaScript. Created by Heroku and now maintained by Salesforce, it provides a structured, plugin-based architecture for building single-command or multi-command CLIs with built-in flags, arguments, help generation, and testing utilities. Oclif powers tools like the Heroku CLI and Salesforce CLI, bringing enterprise-grade CLI patterns to Node.js.
