JortJams is a music discovery tool for the fediverse. It looks like this:
JortJams follows hashtags seen on Mastodon, Pleroma, and GNU Social servers, finds music links in tagged public statuses, adds that music to a catalog, and helps you set up playlists from that catalog. In future releases, JortJams will be enhanced to speak enough of the ActivityPub protocol to follow accounts on servers that also speak ActivityPub.
There is lots of work to do on JortJams before an initial release can be made, but you can still download AppImages for Linux if you want to try out JortJams in its current state.
Please check out the quick start guide, a feature tour, or how it works.
