## What it is
zvm (Zig Version Manager) is a single-binary CLI tool for installing, upgrading, and switching between multiple versions of the Zig programming language, including master/nightly builds and the Zig Language Server (ZLS). It is written in Go and runs on Linux, macOS, Windows, BSD, Solaris, and Plan 9.

## Use cases
- install multiple versions of zig side by side
- switch zig versions per project
- keep up with zig master nightly builds
- install zig language server zls
- upgrade zig toolchain from the command line

## When to choose
- you work on multiple Zig projects pinned to different compiler versions
- you track Zig's fast-moving master branch and need frequent updates
- you want a static single-binary version manager that works across many platforms including Plan 9

## When to avoid
- you don't use the Zig language
- you prefer managing toolchains through your OS package manager
- you need a general-purpose version manager for many languages rather than Zig specifically
