I'm running Komga as well. I'm finding Jellyfin is pretty plug and play. Komga takes a while to setup. For my collection it took about 2 days to run the setup. Jellyfin took about an hour. Jellyfin has a built in reader that works with web browsers plus they have clients for Android TV, Roku, etc. It's a media server/client application like Emby and Kodi.

Overall, it's fast to navigate and setting up faster even then Ubooquity I'm finding, however Ubooquity is still faster in loading comics once you find them. Jellyfin is easy to navigate. It reads comicinfo.xml (both comicrack and comicbooklover) in .cbz or side-cared comicinfo.xml which Marten requested. It allows for the publisher - volume navigation. It follows the same naming schema as Ubooquity. Sees and displays folder.jpg for Publishers and Volumes. It's open sourced so it can be customized. Of course, Jellyfin's main focus is in video and audio but I was surprised by how well it works. I don't think it has comictaggging ability but I use Mylar for comictagging and generation volume folder.jpgs. 

One negative is that there does not appear to be a zoom setting in the reader.

Tried Jellyfin with Bookshelf. It does the job and it is open sourced.

Thanks but a solution would be to have a database backup feature or fix the leak but without any updates nothing can be resolved.

Has this issue ever been resolved? 

So it's been a while since the last update, any idea or time frame for the next release?

I agree, For comics, having a publisher\series title simplifies navigation.

For metadata and organization check with For comic tagging use comictagger or equivalent.

EvilHero can help.

Comixology2 does not appear to be compatible with latest Mylar generated series.json Version 1.0.1

Sweet job. Impressed. Does it do publishers as well?

Is the there a guide on how to use PageBuilder for Windows 10. Mylar folder format.

Where to place the scripts?
