I’m using https://sftpgo.com/, which uses WebDAV. It’s as basic as can be but I like it because it’s so basic. I can mount drives in windows and Linux and it has a basic webui for file management. The only problem for me is mobile apps. I’m trying out OwlFiles on Android and iOS; the free version includes WebDAV support, which works well.
Spot on. You can’t self host without reading app and system logs.
