Each course defines the lab environment learners practice in — the programming languages and compiler profiles behind the Dynamic Workspace.

​
Choosing languages

Pick the programming language(s) your course teaches. xKat supports many languages through configurable compiler profiles, so learners get authentic behavior for the language you choose.

​
Compiler profiles

A compiler profile defines how a learner’s code is built and run on the remote servers — the language, version, and execution settings. Selecting the right profile ensures:
  • Errors and output match the real toolchain.
  • Exercises behave consistently for every learner.

​
Workspace layout

Your choice of lesson type drives the workspace layout learners see:

Editor + Terminal

For backend and CLI lessons.

Editor + Preview

For frontend lessons.
Course cards display workspace badges based on this configuration, so learners know what to expect before enrolling.
