Rocksky is a decentralized, open-source alternative to Last.fm built on the AT Protocol — the same protocol that powers Bluesky. It tracks (“scrobbles”) the songs you play across your music apps and publishes them to your own decentralized identity, so your listening history belongs to you, not a single company.

Sign in to rocksky.app

The hosted version is the fastest way to get started. Sign in with Bluesky and connect a source.

Quick start

A 5-minute walkthrough: sign in, connect a source, start scrobbling.

​
Why Rocksky?

  • You own your data. Scrobbles live on your AT Protocol PDS, not on a vendor-controlled server. Export, migrate, or self-host whenever you want.
  • Works with what you already use. Spotify, Jellyfin, Navidrome, Kodi, Pano Scrobbler, WebScrobbler, plus anything that speaks the Last.fm or ListenBrainz protocol.
  • Real-time and social. A live Stories feed shows what people you follow are playing right now. Likes and shoutbox comments are first-class.
  • Open source. Self-host the whole stack, build integrations, or contribute on Tangled.

​
What is “scrobbling”?

Scrobbling means automatically recording the track you’re listening to — artist, title, album, timestamp, duration — and publishing it to your profile. Rocksky scrobbles from your music apps in real time and makes the history queryable, shareable, and portable.

​
How it works

1

Sign in with Bluesky

Use any AT Protocol identity. No separate Rocksky account to manage.
2

Connect your music sources

Spotify connects in one click. Self-hosted players (Jellyfin, Navidrome, Kodi) point their ListenBrainz/Last.fm scrobbler at the Rocksky endpoint.
3

Listen normally

Your plays show up on your profile and in the Stories feed within seconds.
4

Explore

Browse charts, find new neighbours, follow friends, react to shouts, or pull your data through the SDKs and API.
