At the current state it’s only single-user, but I’m working on a multi-user implementation. It should be available as soon as I have a proper implementation for the ActivityPub Group actor (similar to what WriteFreely already does, where you have a Group @blog actor that aggregates post from multiple Person actors). That would also unlock full compatibility with Lemmy/NodeBB and other threadiverse implementations. But it takes a while to get done right - and a multi-user set up is also a design challenge when your selling point is to have a blog running on a single folder with Markdown files.

About a free instance, it’s not currently available (you’ll need your own domain and host and then you can just spin up a Docker container), but AFAIK YunoHost is considering adding it to their offering.

I’ll test it just in case by giving @fabio@manganiello.blog a shout

–EDIT–

Interesting, this actually looks like a bug in my implementation. It’s not about Lemmy or Mastodon (at least in the case of receiving loose mentions), it’s about the REPLY type that was ignored. Should be fixed now 🙂

There’s an example with LaTeX here https://blog.platypush.tech/article/Build-an-open-source-drone-with-a-Raspberry-Pi-and-Platypush

It doesn’t fully work with Lemmy yet, but it should work from a Mastodon/Pleroma account.

Full federation with Lemmy is still an open point because it requires me to properly implement a Group actor for full threadiverse compatibility. From what I’ve seen so far even Akkoma hasn’t implemented it properly.
