I use [https://syncthing.net/](Syncthing) because it's serverless, works on various Linuxes and Android, pretty easy to set up, and I trust it.

I trust it because I can get it from 3rd-party repos — Debian, Fedora, F-Droid — and I trust that they wouldn't all allow malicious software that claims all communication is encrypted.

Syncthing's forum uses Discourse. The whole thing just smells of competence.

Of course, it may not suit you.
