Fedibook groups just got a major rewrite.

Groups now work as a ActivityPub group actors — meaning members from Mastodon, Pixelfed, and other Fediverse platforms can join and participate, not just Fedibook users.

Invite a @mastodon.social friend to your group, they accept the follow request, and group posts start appearing in their home timeline. They can post back via DM. It just works.

On Fedibook, groups looks just like that face-thing.

I've had an inspiring first week with Fedibook. Your feedback has been truly inspiring. It started as a provocation and an experiment — but I have decided to turn this into a proper open source project. My first ever!

If you tested on dev1.fedibook.dk — come to https://fedibook.net. The new showcase instance where we will run the latest released code. Or even better, run your own instance and friend request me @sindum@fedibook.net.

I'm heading off on holiday, but I wanted to share what I'm hoping we can build together:

Your Friendly Neighborhood Social Network... One that is there for you when you want to take a moment to connect and follow up. That shows your feed from friends, follows and groups. Nothing more. With a UI that focuses on that rather than keeping your attention.

Jump over to my blog for this post with a little more detail.

I’m disappointed, this doesn’t seem to be about books.

@Territorial sorry for that misunderstanding. It's a fediverse addressbook.

It's been a fun weekend building a new working fediverse applikation.

The tech stack so far..

Backend: Go — fast, simple, great concurrency. No magic, just code.

Frontend: SvelteKit — feels like writing HTML that actually works. SSR out of the box.

Database: PostgreSQL — boring in the best possible way.

Queue: Asynq + Redis — async ActivityPub delivery with retry logic. Workers run separately from the API.

Federation: ActivityPub — HTTP signatures, shared inbox, fan-out delivery for groups and followers.

Infra: Docker Compose — one file per instance, easy to spin up new nodes.

Everything self-hostable. No cloud dependencies. No vendor lock-in.

Still early days — but the foundation feels solid.

And yes - A lot of help fra Claude code. I decided to go all in an use big tech to fight big tech.
