Feddit.frActivity Pub: Can I join a PeerTube or Mastodon server using a Lemmy account?
submitted by
Hey, I am currently trying to understand a bit better what the Activity Pub allows and what it doesn't as I am preparing a presentation on that topic.
On Lemmy I can join other servers without having to recreate an account. Does that also work for across Activity Pub supporting software? Could I join a PeerTube page and then post there? Could I upload videos? Could I join Mastodon or Pixelfed and post images?
On piefed you can join :
- Peertube channel : https://tarte.nuage-libre.fr/topic/peertube/mondelibre and crosspost them.
- in late 2025 : follow mastodon account.
- follow Pixelfed : not supported.
- later in 2026, mobilizon : we can create event post. The base is ready for futur federation with mobilizon : https://codeberg.org/rimu/pyfedi/issues/291
On mbin, you can join :
- peertube channel
- mastodon account
- pixelfed (probably supported but i don't know well mbin)
Lemmy
- peertube : i got bad result with peertube but maybe over time they solved it, i haven't retested it. It was possible but you had to manually retrieve the video
- mastodon : not supported.
People from mastodon, pixelfed...can post on lemmy, mbin, piefed. They need to mention the forumverse community. Eg :
@forumlibre@jlai.lu
I often recommand this formatting on mastodon :
Another note : markdown may not be supported accross fediverse software. For example : https://piefed.social/post/1004603
Peertube on Lemmy was AFAIK recently fixed.
Great, i'm testing it. Well there is some federation issue. Some of these works. It's hard to give a good diagnostic.
Thank you! @VoxAliorum@lemmy.ml fyi
