Yes, it is, as you can see by being under the `elixir-lang` github org

Here's a blog post a year ago announcing the merge of 3 LSP projects into an official one: https://elixir-lang.org/blog/2024/08/15/welcome-elixir-langu...

“Official” means built by the creators of Elixir itself

Elixir has more contributors than just Jose (though he is the OG / creator / leader)

As with my comment in another tree, no, none of the Elixir core team or Dashbit employees are directly involved with this effort, though they may be advising informally and will likely submit a PR here and there.

I'm a bit surprised by that. Isn't an LSP for a language like Elixir a close integration with the runtime, compiler, etc?

In an ideal world, yes, my belief is that that produces the best results.
