I have been working on, and using Portal to self-host my own "cloud" services at my domain (jeff393.com), to replace Google and other services.

https://portalplatform.net

This is what I'm running now:

- Files (Syncthing)

- Email (Mail Server + Thunderbird / Evolution)

- Chat (XMPP/Jabber + Weechat)

- VPN (OpenVPN)

- Blog (Ghost + Telescope)

- Etherpad (document creation / collaboration)

- Mumble (voice chat)

- Tor (privacy)
