Yep, I use KeePass synced over my selfhosted nginx server. But you can use Dropbox/Google Drive/etc. just as easily.

I would like to also recommend the Firefox extension 'Kee' for autofill. On Android there is the 'Keepass2Android' app. Both are open source and work well.

I also recommend the KeePass plugin 'Yet Another Favicon Downloader'. It downloads favicons from websites for your password entries.

Also 'Keebuntu' is a plugin that makes 'minimize to tray icon' work for me on Linux.
