asdf[1] mentioned in the article is similar to anyenv but instead of being a wrapper around *env, it implements its own simple framework for creating a version manager (e.g. [2]). Usually asdf plugin uses the same underlying installer as its *env equivalent (e.g. asdf-python uses python-build, asdf-ruby uses ruby-build, asdf-erlang uses kerl).
