Comparing Elixir language servers: ElixirLS, Lexical, and Next LS
I frequently switch between ElixirLS, Lexical, and Next LS in order to test each out and compare/contrast. I decided to create a brief feature comparison matrix with some of my findings: Elixir Language Server Comparisons · GitHub
I reached out to some authors and devs familiar with each tool in order to be as fair as possible. Each of these tools is a large undertaking and takes tons of time and effort from the maintainers. A simple 2D comparison table can’t tell the whole story, so take it with a grain of salt. I’ll be doing my best to maintain and update the list as tooling evolves and adds/changes functionality.

That’s really cool. One thing I think none of the language servers support right now is working inside liveview sigils, things like go to definition, hover,…
That’s something that might be useful to track as well?

Thanks for putting that together!

Oh yes, go to definition on HEEX components would be magical

Seems to be in Sublime Text. This is the functionality I most depend on in my project; as you point out, back when I was using VSCode I had it working there, too.
To be honest, the way the different Elixir projects are used in my code base, per workspace directory LSP processes don’t bother me and is consistent with what I need to manage the monorepo in the editor.
