Just build Mac apps then. Claude Code can help you whip up real native apps without any Glaze dependencies just fine. I’ve built 4 Mac and iOS apps in the last 6 months for my own use. I even have my own HN app for iOS and Mac.
LLMs absolutely understand and write good Elixir. I've done complex OTP and distributed work in tandem with Sonnet/Opus and they understand it well and happily keep up. All the Elixir constructs distinct from ruby are well applied: pipes, multiple function clauses, pattern matching, etc.
I can say that anecdotally, CC/Codex are significantly more accurate and faster working with our 250K lines of Elixir than our 25K lines of JS (though not typescript).
I have a `codex-review` skill with a shell script that uses the Codex CLI with a prompt. It tells Claude to use Codex as a review partner and to push back if it disagrees. They will go through 3 or 4 back-and-forth iterations some times before they find consensus. It's not perfect, but it does help because Claude will point out the things Codex found and give it credit.
I've been using a development server for about 9 years and the best thing I ever did was move to a machine with a low-power Xeon D for a time. It made development painful enough that I quickly fixed the performance issues I was able to overlook on more powerful hardware. I recommend it, even just as an exercise.
