There has been a thread to discuss the Stack Overflow Developer Survey on this forum every year since 2018, so here’s yet another one for 2025 :slightly_smiling_face:. This year, our ecosystem is once again well represented with Elixir, Erlang, Gleam, and Phoenix available as technology options!

The survey is said to remain open for just a few weeks.

I have to say I think this is probably the main reason that anyone would visit Stack Overflow these days. Well that and following some search results. AI is killing Stack Overflow and that’s a bit of a pity.

You’re not kidding Krister! Seems like every other question involved AI.

Should call it the “Stack Overflow AI Survey” instead of the Developer Survey. There were only about half a dozen questions about specific programming languages and tools :frowning: Next year I’ll get an LLM to fill it out.

The results are in! 2025 Stack Overflow Developer Survey

Highlights for the BEAM community:

  • 2.7% of respondents report having used Elixir for “extensive development work”, up from 2.1% last year
  • Similarly, 1.5% of the respondents used Erlang, up from 0.9% last year
  • Gleam and Elixir share the 2nd and 3rd spots for most admired programming languages
  • Phoenix is the most admired web framework in 2025, a trend since 2023

Erlang and Elixir used to be the top paying technologies in the 2024 survey, but they seem to have dropped the category entirely in 2025. Typically SO release the data sets for download later, so perhaps we’ll get to see more in the future for the categories not presented on the website.

Another curious meta-insight is that this year’s survey got 49_000+ respondents, last year’s survey got 65_000+, and 2023 boasted answers from 90_000+ developers.

I can only speak for myself but after I saw how many of their questions were tailored towards AI, I have dropped their survey and never finished it.

I have to admit, I was annoyed by them as well and forced myself through them.

Even though weighing models by preference was hard, as I don’t really care for the model used, but instead use some product or frontend, and do not care what model is used in the backend, as it might change at anytime, if the designers of the product think the product would benefit from it.

So I often left them at defaults or otherwise neutrally answered.
