I built an EPUB reader for macOS and iOS that implements Calibre's wireless device connection protocol, so I figured this was the right place to share it.
How it works:
- On your Mac, enable the Calibre server in BookShelves (Settings → Advanced → Calibre Wireless Server)
- In Calibre desktop, click Connect/Share — BookShelves shows up as a wireless device
- Send books over your local network. Metadata (title, author, series, tags) carries over intact
- iCloud sync means anything you send from Calibre on your Mac appears on your iPhone/iPad automatically
It handles EPUB, PDF, and comic archives (CBZ/CBR/CB7). The Calibre integration was one of the first things I built because I wanted to keep using Calibre for library management without needing cables or manual file transfers.

Happy to answer questions about the wireless protocol implementation or anything else.
