Learn how cpak works by making it decide.

Follow a course, edit real manifests and run cpak's decision code in the browser. Read everything without an account, then sign in when you want progress across machines or a credential.

Courses

Workspaces

Use cpak before touching your machine

These run a pinned build of cpak's own decision code in your browser. Write the input you would use on Linux and read the same validation, policy or migration answer.
