Free online Lua 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 Lua and many other languages, without installing a toolchain.
What you see on this page is JDoodle’s free Lua compiler. Write Lua in the editor, press Execute, and JDoodle runs it on its servers. You do not install Lua, and you do not need a JDoodle account to run code.
Online Lua editor
JDoodle’s Lua editor on this page highlights syntax, completes as you type, matches brackets, and folds blocks. It is an online Lua editor and a compiler together: you write here, then Execute runs your program on JDoodle’s servers.

Frequently asked questions
Is JDoodle’s online Lua compiler free?
Yes. JDoodle lets you write and run Lua without paying. A JDoodle account is only needed to save projects, use more AI credits, or unlock faster workspaces.
Do I need to install Lua to use JDoodle?
No. JDoodle runs Lua on its servers. Open this page in a browser and execute.
Which Lua 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 5.3.2, 5.3.4, 5.3.5, 5.4.3, 5.4.6, and 5.4.8.
Can I add Libraries on JDoodle?
Yes, if the package is public. Private or local packages are not supported on this JDoodle page.
Can I run a multi-file Lua project online?
Not on this page, which runs a single Lua file. For several files in one project, open the JDoodle Lua IDE. Everything else works the same on both.
Is this an online Lua editor or a compiler?
Both. The page is an online Lua 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.
