Getting Started
Install a package for your platform, or run the web version at web.koodoreader.com. The README includes installation options, including package managers and Docker, plus development instructions. See the repository README for details.
Considerations
- The project is licensed under AGPL-3.0, which has licensing obligations to consider when modifying or distributing it.
- Sync and backup depend on configuring supported storage services or protocols. The README lists these integrations but does not imply they are configured automatically.
- Kindle and Mobipocket support is specified for DRM-free files, so it is not a general solution for DRM-protected books.
- The project supports several platforms, but setup and available installation methods may differ by platform. Consult the official download page and documentation before deployment.
