asdf

ELI5 — The Vibe Check

asdf is the 'one version manager to rule them all' — it manages versions of Node, Python, Ruby, Go, Terraform, and basically anything through a plugin system. Instead of having nvm for Node, pyenv for Python, and rbenv for Ruby, you have asdf for everything. It's like consolidating all your remote controls into one universal remote.

Real Talk

asdf is an extendable version manager that supports multiple languages and tools through a plugin architecture. It manages runtime versions via .tool-versions files, providing a unified interface for Node.js, Python, Ruby, Go, Terraform, and hundreds of other tools. Plugins handle installation and version switching per tool.
