Elixir can't run inline (yet)

Some languages need a real compiler or runtime that doesn't fit in a browser. But you can run Elixir instantly on these free platforms:

Open in Replit ↗ Open in OneCompiler ↗

Sample Elixir code:

Elixir example

# Phoenix LiveView counter
defmodule Counter do
    use Phoenix.LiveView
    
    def handle_event("inc", _, socket) do
        {:noreply, update(socket, :count, &(&1 + 1))}
    end
end

A note on this playground

Code runs in your browser using open-source engines (Pyodide for Python, native JS for JavaScript, AlaSQL for SQL). Nothing is sent to OneCity's servers. No accounts, no tracking. If you save your work, copy-paste it somewhere else — refreshing the page resets the editor.
