## What it is
Openlib is an open-source Flutter app for searching, downloading, and reading books from Anna's Archive, a shadow library. It includes a built-in reader supporting EPUB and PDF formats and works by scraping Anna's Archive responses since no official API exists.

## Use cases
- download free books from anna's archive on android
- read epub and pdf books with a built-in reader
- search and filter trending books from a shadow library
- open downloaded books in my favorite ebook reader app
- f-droid app to download ebooks from z-library and libgen mirrors

## When to choose
- you want an open-source, ad-free mobile app to access Anna's Archive books
- you need offline reading of EPUB and PDF books on Android
- you prefer installing from F-Droid or IzzyOnDroid rather than Play Store

## When to avoid
- you need iOS, desktop, or web support - it targets Android
- you require production stability - the app is in beta with known bugs
- you need formats beyond EPUB and PDF, such as CBZ or AZW3, which are not yet supported
- publishing or using such an app may violate local laws or store policies
