Self-hosted Koito[0] and glad I left Last.fm.

Not even a good first-party export, gotta use some hacked together third-party one to get your data out.

ListenBrainz[0] is a decent alternative if you don't want to self-host. You can import your Last.fm scrobbles there pretty easily.

A lot of people run both koito and listenbrainz

As someone doing exactly this, shoutout to FoxxMD/multi-scrobbler[0] for keeping all my music databases in sync.
