If you **switch between development projects which expect different environments**, specifically different runtime versions or ambient libraries,
or **you are tired of all kinds of cumbersome environment configurations**, `vfox` is the ideal choice for you.
## Introduction
**`vfox` is a cross-platform version manager(similar to `nvm`, `fvm`, `sdkman`, `asdf-vm`, etc.), extendable via plugins**. It allows you to quickly install
and switch between different environment you need via the command line.
## Why use vfox?
- **cross-platform support** (**Windows**, Linux, macOS)
- **consistent commands** to manage all your languages
- supports **different versions for different projects, different shells, and globally**.
- simple **plugin system** to add support for your runtime of choice
- **automatically switches** runtime versions as you traverse your project
- support for existing config files `.node-version`, `.nvmrc`, `.sdkmanrc` for easy migration
- shell completion available for common shells (Bash, ZSH, Powershell, Clink)
