LightNovelReader

Project Overview

LightNovelReader is an open-source Android light novel app written in Kotlin and Jetpack Compose, lightweight and smooth to read. It offers caching with offline-first reading, multiple switchable data sources, a bookshelf system, and EPUB export, and supports custom data sources through plugins. The app ships no content; you add data sources yourself.

A Compose reader driven by multiple data sources, focused on light novels.

Key Features

• Multiple data sources: switch between sources with independent data, and even read manga
• Explore and recommendations: discover new books, ranking lists, tag categories, and keyword search
• Caching and offline: cache book content for an offline-first reading experience
• Bookshelf: create and name shelves, favorite books, and get update notifications
• EPUB export: export books as EPUB files
• Plugin extension: add custom data sources and plugins, with an official template and development guide
• Reading UI: built with Jetpack Compose, supporting Android 7.0 through 15

Target Audience

• Android users who read light novels
• Readers needing multiple sources and offline caching
• People who want to export favorites to EPUB
• Developers building custom data sources for the reader
