Frequently asked questions
Questions about scrobbling, trackers and portable records.
Start with the practical difference. Follow the project link when an answer depends on current behaviour.
Anime is a separate filter because it helps people find projects that track episodes, specials, split releases, continuing titles and rewatches. It is a navigation choice, not a claim that anime sits outside film or television. A project can appear under anime and another media type.
Projects differ in media scope, capture method, hosting model and the records they keep. Some receive playback events, some provide a diary, some keep listening history, and some store a self-hosted record across several media.
| Project | Main scope | Typical record | Useful when |
|---|---|---|---|
| Fasti | 11 media types | Library, history and progress | A local-first, self-hosted cross-media record is required. |
| Last.fm | Music | Submitted listens | Players and services submit listening activity. |
| ListenBrainz | Music | Open listening history | An open-source service and exportable listening data are required. |
| Trakt | Film & TV | History, progress and playback | Media applications report playback activity. |
| Simkl | Film, TV & Anime | History, lists and episode state | One service covers its three advertised media areas. |
| Letterboxd | Film | Dated diary entry, rating, list | The task is film logging rather than live playback progress. |
| Ryot | All Media & Fitness | Multi-media tracking & workouts | Comprehensive self-hosted tracking with fitness. |
A portable record should preserve stable event identity, source-local media identity, event and recorded times, native progress in the medium's native unit, provenance (playback vs import vs manual), correction or deletion state, and idempotent deduplication keys.
- Stable event identifier: Content-addressed hash or UUIDv7.
- Source-local media identity: MusicBrainz, TMDB, OpenLibrary, or source provider coordinates.
- Event & recorded times: ISO 8601 timestamps capturing both the actual playback moment and storage commit.
- Native progress: Elapsed seconds, page counts, or episode offset before percentage loss.
- Provenance: Explicit indication of capture method (active playback, diary import, batch sync).
