Can I self-host this? If not, then how can I be sure that your server is running the version of the software in the open-sourced repo?

Yes, see https://github.com/haiwen/ for all the seafile components.

Why would you need to be sure of that?

[stephenr]

Because they can say "hey look at our code here" when in fact they're running something else entirely.

But that does not matter if you trust your client and everything gets encrypted locally. That's the entire point of client-side encryption, not having to trust the server. Just review and then compile the client. And just self-hosting the server will not make you any saver because the client may be rogue and send your data to anyone.
