**Rocksky** is a decentralized, open-source alternative to Last.fm built on the
[AT Protocol](https://atproto.com) — the same protocol that powers
[Bluesky](https://bsky.app). 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.

## 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.
- **Bring your own music and storage.** Upload music to your own S3-compatible
  bucket or use Rocksky storage. Stream your library with any
  [Navidrome / Subsonic client](/integrations/navidrome-server) or
  [Jellyfin client](/integrations/jellyfin-server).
- **Open source.** [Self-host the whole stack](https://tangled.org/@rocksky.app/rocksky),
  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

<Steps>
  <Step title="Sign in with Bluesky">
    Use any AT Protocol identity. No separate Rocksky account to manage.
  </Step>
  <Step title="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.
  </Step>
  <Step title="Listen normally">
    Your plays show up on your profile and in the Stories feed within seconds.
  </Step>
  <Step title="Explore">
    Browse charts, find new neighbours, follow friends, react to shouts, or
    pull your data through the [SDKs](/sdks/overview) and
    [API](/api-reference/introduction).
  </Step>
</Steps>
