I have noticed some odd gaps. One being Home Inventory software. Multiple great options for Windows and Mac. Linux options are basically self host a web app or do the same thing with a spreadsheet.

That's why I selfhost a comic/manga reading app, and why I self-host media services in general. I use mango [1] but I see people discussing Komga [2] a lot. [1]: https://github.com/hkalexling/Mango [2]: https://github.com/gotson/komga. - Source: Hacker News / about 2 years ago

For comics and manga I recommend you this one https://github.com/gotson/komga which has nice integration with third app parties specially Tachiyomi. Source: over 2 years ago
