Online Elixir Compiler
Write Elixir in the browser and run it on our machines. The editor is opening.
Free online Elixir compiler and editor
JDoodle is an online IDE that has served the programming community since 2013. You write, compile, and run code in the browser for Elixir and many other languages, without installing a toolchain.
What you see on this page is JDoodle’s free Elixir compiler. Write Elixir in the editor, press Execute, and JDoodle runs it on its servers. You do not install Elixir, and you do not need a JDoodle account to run code.
Online Elixir editor
JDoodle’s Elixir editor on this page highlights syntax, completes as you type, matches brackets, and folds blocks. It is an online Elixir editor and a compiler together: you write here, then Execute runs your program on JDoodle’s servers.

Frequently asked questions
Is JDoodle’s online Elixir compiler free?
Yes. JDoodle lets you write and run Elixir without paying. A JDoodle account is only needed to save projects, use more AI credits, or unlock faster workspaces.
Do I need to install Elixir to use JDoodle?
No. JDoodle runs Elixir on its servers. Open this page in a browser and execute.
Which Elixir version should I pick on JDoodle?
Choose the version that matches the course or codebase you are working against from the version menu. The builds JDoodle has installed are 1.3.4, 1.5.2, 1.6.4, 1.9.1, 1.12.2, 1.15.7, and 1.19.5.
Can I run a multi-file Elixir project online?
Not on this page, which runs a single Elixir file. One file starts faster, so this page suits exercises and practice. For classes, packages and libraries split across files, open the JDoodle Elixir IDE. Everything else works the same on both.
Is this an online Elixir editor or a compiler?
Both. The page is an online Elixir editor and it compiles and runs what you write.
Input, interactive runs, files, and the rest of the editor work the same on every language. See the JDoodle IDE documentation.
