What I can recommend for now everything based on alchemist-server:
- Atom + https://github.com/msaraiva/atom-elixir
- Spacemacs + Alchemist plugin -> you can check forum Spacemacs - General Discussion, Blog Posts, Wiki
- vim + https://github.com/slashmili/alchemist.vim
- sublime https://github.com/smashedtoatoms/sublime-elixir-alchemist
Mayebe in future Intelij + elixir plugin https://github.com/KronicDeth/intellij-elixir
