Since Kodoo Reader is an Electron-based app, it's no surprise that the GUI is modern and stylish. You can also read FictionBooks (FB2), Markdown, Rich Text Format (RTF), and the basic Office documents such as DOC and DOCX. It also support all the popular eBook formats out there such as PDF, Mobi, Epub, as well as most comic book-related formats CBR, CBZ, and CBT. One of the best aspects of Koodo Reader is that it runs on pretty much all major OSes out there, starting with Windows (7+), macOS (10.11+), as well as all Linux distributions (since it's available in a wide array of packages such as AppImage, DEB, SNAP, and RPM). To top it all off, it's also very good-looking, has nice organization options, and pretty much all features a typical user might want and need. It's also open-source, community-driven, cross-platform, and supports a wide array of formats.

Koodo Reader is one of the best eBook readers for Linux.
