And that was just going through top google results. Not all of them might still work, some of them now only work properly if you self-host with your own API key. I also found some apps on my phone that had recent reviews that said they still worked.

As I said, I’m not using reddit anymore I don’t really want to get into it that much. But it’s obvious they are still around (and of course … some people still love reddit and know how to code …).

If you genuinly want to find the best still working 3rd party reddit client, I’m not in a position to tell you which one it is. My entire point is that there is some “best 3rd party client” by what ever metric you choose. Even if it’s shitty compared to lemmy.
