asdf vs goenv

asdf is a free, open-source version manager for Linux and macOS. It gives project teams one command interface and a shared `.tool-versions` file for selecting exact versions of multiple tools and runtimes. Plugins support tools such as Node.js, Ruby, and Elixir, while the plugin API allows additional tools. When a command runs, asdf searches for configuration from the current directory upward toward the home directory, then uses shims to launch the selected executable. Existing `.ruby-version`, `.nvmrc`, and `.node-version` files can be supported per plugin. Listed shell support includes Bash, ZSH, Fish, and Elvish, with completions. A GitHub Action uses `.tool-versions` in CI/CD workflows. Installation options include Homebrew, Zypper, Pacman, precompiled binaries, Go, and source builds. asdf manages tool versions rather than system packages or upstream dependencies. If no version is set, execution errors unless the tool is configured as `system`.

goenv manages Go versions on Linux and macOS using a model similar to pyenv and rbenv. It supports global selections, per-project versions, and environment-variable overrides. Shim executables placed in PATH route Go commands to the selected installation, enabling automatic switching and project version pinning. The installation guide says goenv downloads prebuilt Go binaries provided by Google, while new Go versions are added automatically on a daily cron schedule. The project identifies v3 as its current stable version and recommends it for new installations; it says v3 is fully backward compatible with v2. Version 2 receives security patches and critical bug fixes, with support ending on or before December 31, 2028. Setup documentation covers Bash and Zsh, including a .bashrc note for Ubuntu. Installation options include Homebrew and ZPlug for Zsh, and the README includes AWS CodeBuild guidance. goenv is free under the MIT license.
