I've been using Phoenix for super basic things for a very long time since I first discovered it at the Elixir meetup in ATX.
I haven't touched it in a while, Since writing code these days, as most of us know, it's basically steering an LLM.
So I wonder how good are LLMs at writing Phoenix or Elixir so to speak? Time for me to create another side project... and figure it out.
They were pretty good a year ago, so I am sure it is even better than that now.
I'd argue that it's one of the best, especially with Tidewave:
I've built several production quality, mid-sized apps in Phoenix/Elixir over the last year using Claude Code (CC). In my experience, it's great, I had better results with this stack than I had with Django when using purely CC. It's token efficient (because of code generator), has great static analysis, and terse (because functional). Phoenix even generates an Agents.md The apps themselves are highly scalable and look great.
