is there is any app that combine several Reddit alternatives into one feed?
Is there is any app that combine all the reddit alternatives inton one feed the same way Openvibe combine Mastodon, Nostr and Bluesky or the same way that Grayjay combine all the YouTube alternatives into one feed.
Does it exist?
Afaik most such Reddit alternatives support RSS feeds, so a RSS reader could be an option.
I think Stealth on FDroid combines Reddit and Lemmy, but I don't really use it much or mess with Reddit anymore...
It supports Reddit only, also the app is dead anyway.
The source code repo had not been updated since more than one year.
Hm... It's out of date for sure, but I just tried it and it definitely works for both Lemmy and Reddit. You can add any instance you'd like to a custom feed.
