The Calibre alternative built for comics, not ebooks
Calibre treats your comics like spreadsheet rows. Shelf Republic treats the cover as the point.
Let's be clear: for EPUB, MOBI and e-reader syncing, Calibre is unbeatable and free, so keep it for your ebooks. But it's an ebook manager that also handles CBR/CBZ, and it shows: comics become second-class rows in a utilitarian database, covers shrunk to thumbnails. Shelf Republic does only comics, and is built to be looked at.

Calibre reorganizes; Shelf Republic respects. Calibre imports books into its own managed folder structure. Shelf Republic reads the structure you already built and never moves a file you didn't ask it to.
When Calibre is the better fit
Your library is mostly ebooks, or you need format conversion and e-reader sync.
When Shelf Republic is the better fit
Comics are the collection and you want to enjoy the covers, not audit a database.
