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