Han Li

Han Li is an independent developer who maintains vfox, a cross-platform command-line utility designed to simplify the juggling of multiple language runtimes and toolchains on a single workstation. Written in Go, vfox acts as an extensible version manager that plugs into PowerShell, bash, or zsh and swaps entire SDK environments—Java, Node.js, Python, Go, Rust, Erlang, and more—through a single, uniform interface. Instead of manually editing PATH variables or nesting shell scripts, users install lightweight “plugin” bundles that fetch, compile, and isolate each SDK release in its own directory; a short command such as `vfox use java@21` then rewrites session variables so that compilers, package managers, and IDEs immediately see the requested version. The approach is popular with polyglot developers, CI maintainers, and classroom instructors who need reproducible builds across projects without container overhead, and it integrates cleanly with existing dot-file managers like starship or oh-my-shell. vfox also exposes Lua hooks for post-install configuration, supports proxy mirrors for enterprise networks, and stores everything under the user profile, eliminating the need for elevated privileges. Han Li distributes the binaries under an Apache 2.0 licence and publishes source, documentation, and plugin registry on the project’s website at vfox.dev. The publisher’s software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest release and permitting batch installation alongside other applications.
