Fast Node Manager (fnm) is a cross-platform Node.js version manager built in Rust. It allows for easy installation, instant startup, and works with .node-version and .nvmrc files. Installation can be done using a script or through package managers like Homebrew, Winget, Scoop, or Chocolatey. fnm also provides completions for supported shells and requires environment variable setup using fnm env.
