  • Calibre – New in Calibre 7.0
    Maybe have a look at Kavita or Ubooquity (possibly Komga, but that's more for comics) https://www.kavitareader.com/ https://vaemendis.net/ubooquity/ https://komga.org/. - Source: Hacker News / almost 3 years ago
  • Are there any iOS comic readers that let you "stream" cbz and cbr files?
    Another option might be Ubooquity – it’s simpler than Komga, but you can start it as a desktop application on your regular computer. Could be a good way to get your feet wet :). Source: over 3 years ago
