asdf is a command-line interface (CLI) tool designed to manage multiple runtime versions for various programming languages and tools. It provides a unified interface to install, switch, and manage different versions of tools like Node.js, Ruby, Python, and more, all from a single command. This eliminates the need for separate version managers for each language, simplifying development environment setup and maintenance.
The tool is ideal for developers, teams, and CI/CD environments that work with projects requiring specific or multiple versions of runtimes. It supports a large ecosystem of existing runtimes through its plugin architecture, allowing users to easily add support for new tools. Key benefits include streamlined project setup, consistent development environments across teams, and smooth migration with support for existing configuration files like `.nvmrc` and `.ruby-version`. It also integrates with GitHub Actions for CI/CD workflows.
