Ah, my apologies, I thought I’d included the links 
Yeah @vit, that’s the correct link to the flatpack.
Links to the three distributions:
- NPM – @atlassian/aui - npm
- ZIP – https://packages.atlassian.com/maven-public/com/atlassian/aui/aui-flat-pack/8.0.0-alpha.3/aui-flat-pack-8.0.0-alpha.3.zip
- P2 – https://packages.atlassian.com/maven-public/com/atlassian/aui/auiplugin/8.0.0-alpha.3/auiplugin-8.0.0-alpha.3.jar
Because it’s on NPM, it will also end up on CDNs like unpkg: UNPKG - @atlassian/aui
