Frequently Asked Questions

Which Ruby version is supported?

We support Ruby 3.x with full access to the standard library including Array, Hash, String methods, and built-in classes.

Can I use Ruby gems?

The standard library is available. For external gems, you would need a local Ruby installation with Bundler.

Is Rails supported?

This is a Ruby code runner, not a full Rails environment. For Rails development, use a local setup or cloud IDE.

Can I test Ruby classes and modules?

Yes, you can define and test classes, modules, mixins, and all Ruby OOP features in the editor.
