I’ve been using CommaFeed for a while and I’m very happy with it. https://github.com/Athou/commafeed/ plus it is actively developed. I’ve reported a couple of small feature requests and the author implemented them very quickly.

As far as I know there are many third party android apps that you can use, but its responsive webUI is good enough, once you install it it is essentially as good as an app.

Devices are named after characters from books I recently read, trying to match the name with the character of the book. But for virtual hosts for services I use their purpose (wiki, files, feed…) because I wasted too much time updating all the bookmarks last time I migrated to a new server.

If security is one of your concerns, search for “HTTP client side certificates”. TL;DR: you can create certificates to authenticate the client and configure the server to allow connections only from trusted devices. It adds extra security because attackers cannot leverage known vulnerabilities on the services you host since they are blocked at http level.

It is a little difficult to find good and updated documentation but I managed to make it work with nginx. The downside is that Firefox mobile doesn’t support them, but Firefox PC and Chrome have no issues.

Of course you want also a server side certificate, the easiest way is to get it from Let’s Encrypt
