@silverpill it's the main thing fedilinks is concerned with, it's primarily an API project. sure, it exists to enable a particular UX, but ultimately the problem it solves is: how can apps implement the UX, if there are no suitable APIs yet?
however, there's a suggestion of adding an "Or open in an app" link within the "remote interaction dialog" shown to logged-out users on mastodon instances. as far as we know there are no implementations of such tho.
