Design system

Postman uses one shared design system so the app feels consistent everywhere.

In simple terms, this means:

• Buttons, inputs, tables, and dropdowns should look and behave the same way across features.
• Spacing, colors, and typography should follow shared tokens, not random custom values.
• Teams should reuse existing UI patterns first, then create new ones only when needed.

In the postman-app codebase, this mostly maps to the platform-ui/ layer and the @postman-app/aether-components package.

If you are building or updating UI, start with Aether docs first:
