When to use Odyssey, ARC, or MUI

If you are building new page UIs

Use only the Odyssey Design Kit and the React library.


Don't use any ARC or Courage components — the styling and code will not be consistent, or work.

If you need a component that doesn't exist yet in Odyssey

Submit your request to the Design System team and substitute MUI components wrapped in our brand styles.

If you are using a pre-1.0 version of Odyssey

Work with your engineering partners to update to Odyssey 1.0 through the THI migration plan. Learn more about migration.

If you are working in ARC UIs and building a new component that will only be used in ARC

Continue designing with the ARC UI kit. At this time, Odyssey's React library can't be used within ARC.
