Our verdict on Koma

Koma brings local comic collections and online manga into one desktop reader for Windows, macOS, and Linux. It suits solo readers who want to browse existing files alongside chapters, volumes, or series from online sources, then keep selected downloads in their library. Its file support spans CBZ/ZIP, CBR/RAR, CB7/7z, CBT/TAR, image folders, PDF, and fixed-layout EPUB, giving it a broad role as a personal collection reader rather than a tool focused only on one comic format.

Reading controls are a notable strength: Koma offers single-page, spread, continuous, webtoon, and presentation modes, plus left-to-right and right-to-left directions. Library scanning helps bring existing collections into view; bookmarks, page notes, reading history, and time tracking add ways to keep track of reading. Online access uses built-in MangaFire support and extensible connectors, and selected content can be downloaded into the library. AniList and MyAnimeList account linking can sync progress, while Discord Rich Presence is also listed as an integration. Readers choosing it for online sources should weigh that connector-based approach against their preferred services.

Koma is free, and the project is MIT-licensed. Its fit is clearest for desktop readers who want local files, online manga, multiple reading layouts, and tracking-service links without paying for the reader. The trade-off is platform scope: it is available on desktop, with no mobile builds released, so readers who need to continue on a phone or tablet should choose an alternative. Support is community-based, which may also be less suitable for anyone looking for a dedicated support channel.
