Add a LANraragi server

Koharia has a built-in LANraragi connection targeting LANraragi 0.9.70 and later. Each Archive is shown as an individual item, Tankoubon archives can be grouped as collections, and server Categories are available as shelf filters.

Prepare the details

• A LANraragi address reachable from the device.
• An API key. Leave it empty when authentication is disabled; servers that restrict access or allow progress writes generally require one.
• Optional public and Wi-Fi LAN addresses for the same server.

Steps

1. Open connection management and choose Add connection → LANraragi.
2. Enter a connection name, server address, and API key when required.
3. Choose a default Category and whether Tankoubon collections should be grouped.
4. Choose whether opening an Archive goes directly to the reader or first shows a page-preview grid.
5. Save the connection and synchronize the catalogue.

Cache and reading

Koharia caches catalogue metadata while online, so cached Archives remain browsable and searchable offline. Metadata cache is not page content; download an Archive manually when it must be readable offline.

Progress is synchronized per Archive. The server must enable progress tracking and grant the API key the required write permission. Mark unread resets local state only and does not clear server progress.

Common issues

• Categories are missing: save the connection and complete one catalogue sync before reopening its settings.
• The preview is empty: page thumbnails and content come from the server, so check that the Archive is still available.
• Progress cannot upload: enable server-side progress tracking and use an API key with write permission.
• Offline reading fails: confirm that the Archive finished downloading, rather than only its catalogue metadata being cached.
