You can currently only share an interface with people who are collaborators on the base. If you want to share the interface with someone who is not yet a collaborator, they will be made a collaborator (with the associated fees$.
Would love to see this feature also. Public, read-only access to an interface (via link) would solve a lot of communication issues. We keep our database up to date and frequently have to run sanitized exports of records to share with other teams. A live interface with those filters in place would be a dream.
Echoing what others have said here. Being able to create an interface to collect public responses would be super beneficial… think crowdsourcing resources without needing to invite each individual person to be a collaborator.
Being able to share interfaces publicly is an increasing need in my work too, since most of the times the public facing information you want to share is not tables with data but a nice visual summary.
+1. Public link is a critical feature to make use of Interfaces overall. We consider using dashboards for a huge set of freelancers and it does not make sense paying for them as collaborators.
