## What it is
goenv is a Go version manager modeled after pyenv and rbenv, letting users switch global, per-project, and environment-variable-overridden Go versions via shims. Version 3 is a Go-based CLI rewrite, with new Go versions added automatically on a daily schedule.

## Use cases
- install and switch between multiple Go versions
- set a per-project Go version
- change the global Go version per user
- override Go version via environment variable in CI
- run commands against multiple Go versions at once

## When to choose
- you work on multiple Go projects requiring different Go toolchain versions
- you want a pyenv/rbenv-style workflow for Go
- you need automatic access to newly released Go versions

## When to avoid
- you only ever need one Go version and can use the official installer
- you prefer nvm-style version managers like gvm
- you need Go version management integrated into a single binary toolchain like asdf already provides
