Mastodon for sure, you can even use mastodon bots from lemmy, and there will be limited compatibilty witth anything else using activity pub.

I don't know who upvoted my deleted comment, but yes, getting remindmebot names right at first try is hard 😶🌫️
I (on lemmy.world) still see your comment, I think delete sync takes a bit with large instances
Oh, that's slightly troubling ... eheh 😅
So apparently Peertube works well, in part because the structure of the two platforms map onto each other well. Communities -> Posts -> Comments = Channels -> Videos -> Comments.
I experimented once, and from memory you can definitely subscribe to a peertube channel here. But I don't know my way around peertube so I don't know how well it works.
What can Lemmy federate with?
Yes.
In theory, it should work with all of them, but in practice it's messy and clunky as all of them use ActivityPub in subtly different ways, with their own extensions and quirks.
Also Lemmy versions pre 0.18 (i want to say, unsure) won't work with GoToSocial or Mastodon instances with secure mode enabled. The recent versions should though.
I have summarized here what I have found out so far, but is currently only available in German https://handbuch.rollenspiel.monster/lemmy/communication/
Completely unrelated but I'm surprised how well Firefox Nightly's built-in translations worked here. Despite being made just by a few universities, working completely offline, and not having any AI bullshit or Google's infinite money and experience it was still comprehensible enough to understand.
There's also Diaspora, and I don't know if Lemmy can federate with that.
Diaspora doesn't use ActivityPub anymore, right? So probably not.
Diaspora* has never supported ActivityPub and doesn’t intend to.
well that was a long read, was interesting tho, think it's safe to say yes they won't be supporting it period, they just didn't wanna say it.
Very interesting read. Their criticism of the framework seems pretty valid. I’ve seen newer users be confused, how can they read Mastodon from Lemmy? Not as easily as reading Mastodon from Mastodon.
Usually it’s enough to explain that every application really is it’s own thing. If they are closely related enough and chose to use features in the same way, and more or less they are different applications for a similar purpose like Mastodon and Calckey, they will probably work well together. The more their functionality differs the more their interoperability will vary. Even Lemmy and Kbin had upvotes that were not interoperable until a few weeks ago, and federating Mastodon and Bookwyrm gets me status updates but that is not the real utility of Bookwyrm imo.
Diaspora could be made to work but they are right that every new federated product will work in unpredictable ways and can be confusing to users.
I've noticed that Lemmy has a hard time federating to non-Lemmy instances. Looking up a user/community on Calckey/Mastodon shows a lot of posts and random things missing.
I noticed this with the blender Peertube instance. Videos are missing.
In theory yes Lemmy should federate with them all of course to be sure if it works on a per instance level you could always try it, As not all mastodon instances seem to work with Lemmy for some reason
Does the mastodon instance need to be up to date for it to work?
Commenting works.
Posting kind of works, bit is kinda wonky because mastodon doesn't have a 'title' field so it just defaults to the first line of the post.
