I do the same thing: systemd to start the BEAM, and all other things are applications included in the BEAM so they don’t need to be started themselves.
If you have a lot of dependencies outside of Elixir (i.e. you do have to use Redis, an NPM server to serve a web-application that includes server-side rendering, and you have an SQL database) then I think any existing tooling should work well; what would an elixir-specific tool for something like this add?
