Manga Sync is a personal-first layer between a canonical manga identity and the providers you read from. The public surface is intentionally small: use the docs to understand the workers, then use the API or Paperback source.
The production surface
There is one public hostname:
https://df.criccadamus.euThe router serves the Nimbus documentation at the hostname root and mounts the
health check and sync API under /api/*, plus the Paperback source repository
under /paperback/.
First steps
Read the worker map
Start with the router, then follow the links to the SyncApi and PaperbackCatalog pages.
Search canonically
Use GET /api/v1/canonical/search?q=... to search AniList and MyAnimeList
records before matching provider-specific entries.
Install the source
Add the production URL from the source repository page in Paperback, then configure its personal API token in the source settings. Save titles to your library before reading so chapter reads sync.
The sync model
The canonical record is the stable identity. MangaDex and Comix are provider adapters matched to that identity; neither provider owns the personal record. Changes are written to the personal Durable Object first, and remote sync is a separate operation.
Provider login state stays with the client that owns it. In particular, Paperback browser cookies are not sent through the sync API.
