Copyparty is an absolutely incredible tour-de-force and has an absolutely insane feature set.

But if you want something rock solid that probably solves your actual problem, I'd recommend looking at rclone - specifically the 'rclone serve webdav' command.

Features of copy party I use regularly:

Search to find epubs for my phone

OPDS to downloads things to koreader

Download file as zip to quickly grab an album from my collection to load to a device

Rclone is great but not exactly the same

I use rclone to give me command line access to Google Drive from Debian. What would be the use case for webdav via rclone? Usually a cloud service like this has a native way to perform file transfers from a browser.

Mac, Windows, and most Linux desktops all support webdav for mounting folders.

That means you can mount, natively on your desktop, anything rclone supports.
