Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Affinity Publisher
- It cannot open native InDesign documents, only IDML exports, so inherited client archives either come across imperfectly or have to be rebuilt from scratch.
- There is no scripting or plugin interface, so studios that automate catalogue or variable data production still need InDesign alongside it.
- Signing in through a Canva account is now part of using the free application, which is a problem for regulated or offline environments that forbid cloud accounts.
- The roadmap belongs to Canva, and the 2025 relaunch already reset the licence model that earlier perpetual buyers paid for, so long-term direction is outside your control.
- Commercial printers and freelance collaborators still expect InDesign packages, so handoff usually means delivering flattened PDFs rather than editable files.
Calibre
- The interface is dense and widely described as unintuitive, with a great deal exposed at once
- Conversion between formats is imperfect, and complex layouts degrade
- Cannot remove DRM, so purchased books from most stores will not convert without third-party plugins
- Heavy for someone who only wants to read rather than manage a library

Only IDML interchange files, and complex layouts lose fidelity. Native INDD files cannot be opened at all.

Calibre: Does it work with Kindle?
Yes, it transfers to Kindle and most other e-readers and converts to the formats they use.
