Initially Webmentions and AP reactions were rendered on separate panels (with the Jinja rendering templates provided by the webmentions and pubby libraries respectively), but then I found that a bit confusing and cluttering, because there were basically two comment sections with two different time-sorted lists of threads. But if people prefer the other way around I could also add it as an option or a filter toggle 🙂

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.

Nextcloud is my best pick. Of course, it does much more than calendars, so if you’re looking for a calendar service that does only that it may be a bit overblown.

Big pros:

• Native WebDAV integration out-of-the-box - which means that you can easily export your calendars through WebDAV URLs in any supported app

• Support for importing external calendars

• If you also use other Nextcloud products (like mail, contacts or office) the integration betweren them is quite well designed

On Android then I use DAVx5 to synchronize calendars and contacts from Nextcloud with my phone, and Etar as a multi-provider calendar app.

You can find a good Searxng instance or run your own (it can also run on a RPi)
