I am using it for python, erlang, elixir and nodejs. It works great on MacOS so far. I used to use a mix of homebrew versions of those tools and some language-specific install scripts like kerl or pyenv. One of my favorite things is to quickly start a new shell with a specific version to test something: 'asdf shell python $ver'. I did try direnv as others mentioned here, but I found it a bit too magical and eventually abandoned it.
