A free and open source manga reader
Requires Android 6.0 or higher.
This fork was created for personal usage, the name Karasu is chosen in theme of my "paranormal" fork collection, all of them are made for personal purposes, to explore the language used to made them, explore new tech, or simply want to add my own twists that may not accepted by upstream as a PR.
Updates are sporadic, sometime fast, sometime slow.
As of the time of writing, this fork is currently focusing on migrating to a much more modern infrastructure, some features may be added, but most changes are happening behind the scene.
- Release calendar. Karasu learns each series' rhythm from the chapter list its source already returned, and shows what your library is expected to release — on its own screen and on a home screen widget. A series that misses its window says so instead of quietly disappearing, and one with too few chapters to guess from admits it has no estimate.
- Updates that ask about the right entries. Background updating checks what is actually due rather than walking the whole library on a timer, so a weekly series is asked once a week instead of six times for the same answer. A separate, cheap pass catches the handful whose window is open right now. Manual updates always ask, so an estimate can never be why you cannot see a chapter.
- Missing chapter detection. Gaps in the numbering are surfaced as ranges, so you can tell a source that is incomplete from a series that skipped a number.
- Yatagarasu — KOReader sync. Push chapters as CBZ to a self-hosted shelf server and read back what you finished on the e-reader. Mark what gets sent from the manga page.
- Merged sources. Read one entry across several sources at once. When a merge is not working, the UI names the reason — extension missing, entry gone, or chapter numbers that do not line up with the other source, which usually means the wrong entry was matched.
- Category rules. An IF / AND / THEN editor that moves entries out of a category on their own. Rules can be exported and imported.
- FlareSolverr support. Optional fallback for Cloudflare challenges the WebView cannot solve.
- Its own tracker credentials. MyAnimeList and AniList authenticate against OAuth apps
registered to Karasu on a
karasu://callback, so the login cannot be captured by another Tachiyomi fork installed on the same device. Shikimori and Bangumi were dropped rather than kept on upstream's credentials. - Protobuf extension index, with a fallback to the older JSON one.
- Disk-cached covers.
