Free & open source

Your manga server,
wherever you read

Kai-Shelf is a cross-platform reader for the manga & comics server you already self-host. Browse your library, read offline, and keep progress in sync — no accounts, no telemetry, just your server.

What it does

Built for reading, not for accounts

Auto server detection

Paste a server URL and Kai-Shelf figures out whether it's talking to Suwayomi, Komga, or Kavita — no manual setup.

Offline downloads

Queue single chapters or batch-download the next 5, next 10, or an entire series. Reading auto-caches upcoming pages in the background.

Paged & webtoon reading

Switch between traditional paged reading and continuous vertical scroll, with reading progress synced back to your server.

Discover new titles

Search installed Suwayomi sources right from the app and add new manga to your library without leaving Kai-Shelf.

Chapter management

Sort chapters ascending or descending, and mark any chapter read or unread manually — auto-marking still happens when you finish a chapter.

No accounts, no telemetry

Kai-Shelf talks directly to the server you already run. Nothing is collected, nothing is proxied.
