What services/tools are folks using for cross-platform file sharing? My household is cross-platform (wife is on #macOS, I have an old macOS system I keep around, and the rest of my systems are #Linux) and I don't foresee that changing any time soon.
@scottslowe For single file sharing now and then: #LocalSend https://localsend.org/ - works on Linux, Android, iOS, Windows, Mac.
For real folder sharing and syncing - #NextCloud.
LocalSend: Share files to nearby devices

LocalSend is a free, open-source, cross-platform file sharing tool that allows you to share files to nearby devices.

@cweiske I use LocalSend now for myself, but it's a good idea to get it installed on her Mac. I've also been looking at more self-hosting, so perhaps NextCloud is a good route there. Thanks!
