rakuyomi is a manga reader plugin for KOReader.
Important
This is a maintained fork of rakuyomi, the continuation of @hanatsumi's original project that Tachibana Shin took over when she stopped using e-readers. Credit for both belongs to them.
The upstream repositories were deleted in 2026, so this fork hosts the releases, the update channel and this guide.
rakuyomi currently supports all Aidoku sources including sources written with legacy SDK or next SDK (Aidoku Community Sources...)
It also supports extensions from LNReader, Mangayomi (JavaScript and Dart), and Tachiyomi/Mihon (Keiyoushi), and plugin image DRM.
Releases are built for Kindle, Kobo, PocketBook, reMarkable, desktop Linux and Apple Silicon macOS.
Android needs the Rakuyomi Bridge companion app to load the Rust server through JNI, and that app went with the upstream account: nothing publishes RakuyomiBridge.apk anymore. The Android target is gone from CI for the same reason, so no rakuyomi-android.zip is released. Only the plugin zip was ever produced there, without the server it needs.

Rakuyomi includes a Telegram bot for syncing Cloudflare cookies from your Android browser to your e-reader.
- Open Telegram and start the bot: t.me/rakuyomi_bot (or your self-hosted instance)
- In KOReader, go to Rakuyomi → Settings → Cookie Sync

/link CODE NAMEto the bot - Install Get cookies.txt LOCALLY in Kiwi Browser
- When a source returns 403, export cookies via the extension and paste the JSON array into the bot chat
The Rust backend automatically syncs cookies on 403 and retries. If the retry also fails, the bot sends a notification so you know to refresh cookies.
See telegram-cookie-bot/README.md for deployment instructions.
