Elm does not officially support server-side development. Evan does consider it a primary goal at this point, but progress on this front has been slow. Nevertheless, there are several independent projects which attempt to explore Elm on the backend.
The primary production-ready full-stack Elm platform is Lamdera, an open-core "unfork" of Elm.<ref>{{Cite AV media |url=https://www.youtube.com/watch?v=nSrucNcwlA8 |title=Mario Rogic - Elm as a Service |date=2019-11-28 |last=Elm Europe |access-date=2025-03-27 |via=YouTube}}</ref><ref>{{Cite AV media |url=https://www.youtube.com/watch?v=3Nn5meBieh4 |title=Building a Meetup clone on Lamdera - Martin Stewart |date=2021-07-23 |last=Elm Online Meetup |access-date=2025-03-27 |via=YouTube}}</ref><ref>{{Cite web |title=Episode 38: Lamdera |url=https://elm-radio.com/episode/lamdera/ |access-date=2025-03-27 |website=Elm Radio Podcast |language=en}}</ref> Evan has also teased Elm Studio, a potential alternative to Lamdera, but it isn't available to the public yet.<ref>{{Cite web |title=Elm Studio |url=https://www.elm.studio/ |access-date=2025-03-27 |website=www.elm.studio}}</ref> Current speculation is that Elm Studio will target C, use Emscripten to compile to WASM, and support type-safe [[Postgres]] table generation.<ref>{{Cite web |date=2021-11-03 |title=Status Update - 3 Nov 2021 |url=https://discourse.elm-lang.org/t/status-update-3-nov-2021/7870/3 |access-date=2025-03-27 |website=Elm |language=en}}</ref> <ref>{{Cite web |last=Cesarini |first=Francesco |date=22 May 2023 |title=@evancz tempting the demo gods… |url=https://xcancel.com/FrancescoC/status/1660591792780111872 |access-date=26 March 2025 |website=[[Twitter]]}}</ref>▼

There were also some attempts in Elm versions prior to 0.19.0 to use the [[BEAM (Erlang virtual machine)]] to run Elm, but they are stuck due to the removal of native code in 0.19.0 and changes to the package manager. One of the projects executed Elm directly on the environment<ref>{{Cite web |url=https://github.com/hkgumbs/elm-beam |title=Kofigumbs/Elm-beam |website=[[GitHub]] |date=24 September 2021}}</ref>, while another one compiled it to Elixir.<ref>{{Cite web |url=https://github.com/wende/elchemy |title=What is it? |website=[[GitHub]] |date=24 September 2021}}</ref>
Finally, the Gren programming language started out a fork of Elm primarily focused on backend support, although its goals have since shifted.
