Unfortunately, I do not. I host my own via Docker. I initially started with the official TTRSS docker that had like a dozen containers but moved to http://ttrss.henry.wang/#about which has been super easy to manage and only has a couple containers.
You bring up a good point. Looking at the URL, it doesn’t reveal anything about saved posts. Bummer. Would be cool if lemmy implemented like Reddit does. I wouldn’t mind providing credentials as TTRSS has that ability. I’ll have to just keep an eye out for future development.
Immich is pretty much a self hosted version of Google Photos. I highly recommend it. It’s under very active development. I’ve been using it for a few months now and it’s been rock solid despite all the dev on it.
