Hi @DataBeli ,
From what I understand, in the Free Edition, Databricks Apps can only be shared with authenticated Databricks users. As public or anonymous access isn’t supported, you can try adding the judges’ email addresses to your workspace and then share the app with them by granting “CAN USE” permissions, they’ll be able to open the link after signing in.
Alternatively, you can run the app locally by copying the code into VS Code (or another IDE) and share that demo with the judges instead.
