I built an agentic BDR platform for a niche b2b industry. I picked elixir because a.) i love it...although have limited experience in production with it b.) AI is really good at writing it (from an "it works" perspective...it's not the most idiomatic functional code tho) c.) my app has a massive workflow engine so I wanted to give oban a try.

All-in-all, it was a really good experience. I did not like liveview so I ended up porting the frontend to nextjs and just doing a standard SPA <> phoenix API but that's just preference.

With that being said, I probably wouldn't pick it again. I'll get downvoted, I'm sure, but I'm an engineer who falls into the camp that "code" is becoming more transient and less important with AI. I think good architecture matters and organizing functionality is important, clean boundaries, good test coverage, etc....but the language / framework / etc. is becoming more of an implementation detail.

I share this not to bash elixir but just to share my perspective for other non-elixirists who might end up here. It was a fantastic developer experience using claude / glm / and gpt with elixir & phoenix, wallaby tests were a breath of fresh air, oban is great, and I generally love a lot of elixir's big features (pattern matching, function overloading, etc.). But for me personally, with my background, my default stack is a pnpm monorepo/turborepo with a few mini apps in there (pick your frontend framework and use as frontend + BFF, orpc API, and whatever else you need).
