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.

Meet Fedibook!

The idea came from thinking about what it actually takes to get regular users onto the fediverse. Mastodon is great (i love it), but the follow-based model feels unfamiliar to some. Friends and Groups though — that's something everyone already understands.

So Fedibook is a fediverse platform built around exactly that, using ActivityPub. Think federated address book meets social network, with the kind of social graph people are already used to.

Current status:

- Friend requests across servers working
- News feed working, with visibility levels: public, friends-only, or local server only

Hoping to open up for early testing and feedback soon. Open source of course.

Playing around with a proof of concept....

Hvordan får vi digital suverænitet ind i valgkampen? Hvor skal jeg stemme for få Microsoft ud af folkeskolen? Eller få offentlige applikationer på europæisk ejet og kontrolleret infrastruktur. Hvem er klar til at forbyde X.

Hvem er klar til at investere og lovgive om open source. Min stemme går til et #opensourcefirst parti der tør investere i vores fremtidige uafhængighed. Afhængighed af amerikansk IT er ikke anderledes end afhængighed af Amerikansk militær. Vi må opruste.
