As comics are called strips in Dutch, and follow a flow, Wolf is the reverse of flow.

A cross-platform comic book reader built with Avalonia UI that supports offline reading and Komga integration.

• EPUB Support: On supported platforms you can import EPUB files either by converting them to CBZ on import or by converting pages on demand while you read

Installation

Android APK

Download the latest APK from the Releases page:

1. Download StripWolf-Android.apk from the latest release
2. On your Android device, enable "Install from unknown sources" in Settings > Security
3. Open the downloaded APK file and follow the installation prompts
4. The app is now ready to use

Note: If you are trying to build the APK yourself or run from Visual Studio, the app is signed with a development key for sideloading. This will conflict with the packages build officially, and you will lose your local comics and information.

Linux

Download the StripWolf-Linux-x64.tar.gz from the Releases page:

mkdir -p ~/StripWolf

• Intel Macs: StripWolf-macOS-x64.tar.gz
• Apple Silicon (M1/M2/M3): StripWolf-macOS-arm64.tar.gz

Extract the archive:

tar -xzvf StripWolf-macOS-*.tar.gz -C ~/Applications

Note: On first run, you may need to allow the app in System Preferences > Security & Privacy if macOS blocks it.
