asdf is a single command‑line interface that manages multiple language runtime versions per project. It is extensible through a large ecosystem of plugins for languages such as Ruby, Node.js, Elixir, Erlang and many more.
Use cases
- Switch between different Node.js versions for each project automatically.
- Maintain separate Ruby versions for legacy and new applications in the same workspace.
- Add support for a new language by installing a community plugin without writing custom scripts.
- Keep a single .tool-versions file in a repository to ensure reproducible builds across CI/CD pipelines.
- Migrate existing .nvmrc, .ruby-version, or .node-version files to asdf without manual conversion.
When to choose
- You need a unified tool to manage many language runtimes across projects.
- You prefer a plugin‑based architecture that can be extended to any language or tool.
- You want per‑directory version switching integrated with your shell.
- You require a solution that works on Linux, macOS, Windows and BSD with the same commands.
When to avoid
- You only work with a single language and already have a dedicated manager that meets all your needs.
- You need a graphical user interface for version management.
- Your workflow depends on IDE‑specific version handling that cannot be scripted via the CLI.
