Atlassian User Interface (AUI) Library
AUI is an open source library. You can include it as a dependency in Atlassian add-on projects; You can also download it as a flat pack archive. To prototype, you can use the online Sandbox Tool directly or from within a flat pack download.
Note: The flat pack does not contain the AUI components that rely on backend functionality.
