What is UI Builder?

UI Builder is a low/no code platform part of service-now that allows you to create portals and workspaces. They are mostly built for workspaces. They are built to be a friendlier place for fulfillers and users to manage and visualise the data within an application.

First of all, it is great ...for what it is built for. If you are building stuff that is out of the box then it is fantastic. However, if you want to customise it then it gets a bit more difficult. It is possible, but it'll be more work than you think.

Adding in a data broker but it isn't showing up on the list? You need to create an ACL with the SysId of the databroker with a type of ux_data_broker, it can be empty but there needs to be one or it will not show.
