vfox is a cross-platform, plugin-extensible version manager (similar to nvm, sdkman, and asdf-vm) for installing and switching SDKs such as Java, Node.js, Go, Python, Flutter, and .NET. Written in Go, it unifies per-project, per-shell, and global version management behind one CLI and one .vfox.toml config, with a simple Lua plugin API and shell hooks for automatic version switching.

Use cases

• manage multiple java or node.js versions on windows without wsl
• switch sdk versions automatically when entering a project directory
• replace nvm, sdkman, fvm, and asdf with a single version manager
• install and switch between python, golang, and flutter from one cli
• share consistent tool versions across a team via one config file
• add version management for a custom runtime via plugins
• migrate from asdf keeping existing .tool-versions or .nvmrc files

When to choose

• You work across Windows, Linux, and macOS and want one consistent version manager everywhere
• You juggle many language runtimes and want a single CLI and config instead of per-language managers
• You need project-level, session-level, or global versions with automatic switching as you change directories
• You want to extend version management to any tool via a simple Lua plugin API
• You are coming from asdf/nvm/sdkman and want compatibility with .tool-versions, .nvmrc, .node-version, or .sdkmanrc

When to avoid

• You only need one language runtime, where a dedicated manager like nvm or pyenv may be simpler
• You rely on CMD, which only supports global scope and is not recommended
• Your CI/Docker pipelines are non-interactive and you prefer not to use vfox exec or container-native tooling
• You depend on a very specific asdf plugin ecosystem or shim-based behavior that vfox does not replicate
