That's it. Digitalocean over and out. The last droplets moved to UpCloud and DNS service moved to Hetzner.

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.
Fedibook this week is out.
A slow week of development — but an exploding week for users. 65 users are now using, testing, and giving feedback, becoming a valuable part of the ongoing direction.
I must admit to being both surprised, humble, and a little proud.

Jeg prædiker nok for koret her – men jeg har gjort en artikel om organisationers brug af udelukkende Big Social til at interagere med deres brugere.
Suveræn Public Service -
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.

A major Proof of concept for #fedibook.
Import your export from Facebook.
I left Facebook in january. AND just imported more than 1000 old post from single upload in a zip file.
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.

A month ago, I set out to build a new federated social network from scratch.
It’s been an incredibly inspiring journey, and today, Fedibook - The **Friends first** fediverse app -- is live, with a small but growing community forming around the showcase instance at https://fedibook.net
I’ve decided to try a weekly newsletter.
Here goes:

Thanks for your curiosity and feedback.

After another exciting 6th week of Fedibook, a somewhat brief weekly update is ready.
Thank you to everyone who has provided feedback and involved me in the interesting world of ActivityPub protocol challenges.

@michael I follow you and have though the same. But sometime a new take on the solution can show the way. This is a POC for now. If the result is a new drive for making e.i. Friendica better that would just as good. Sometimes it takes a new-kid-on-the-block to get things moving. I really really like to se a fediverse SoMe for the masses.

@kallekn@mastodonsweden.se beklager. En klassisk fejl fra min side. Mit betaling kort var udløbet og jeg er travlt optaget af at lave spejderlejr.

@julian Thanks!
Groups use the FEP-1b12 pattern — Group actors, Follow to join, Create to post, Announce to fan-out — but with one current limitation: group federation is Fedibook-to-Fedibook only for now. Non-Fedibook
instances get a Reject on Follow.
It's a pragmatic shortcut to get something working for now. Full cross-platform group support (Mastodon, Lemmy, etc.) is the goal if it proves feasible.

Playing around with a proof of concept....
Post 2 of 2 - Read the entire post at https://about.fedibook.net/friends-vs-mutual-follows/
I think I need to make "Friends" an active decision. Not just a mutual follow. I still wan't to be able to be "Friends" with another ActivityPub user - not only Fedebook.
Option 1 - Mark as friend / two feeds
Enable the user to make a mutual follow as friend. This will enable the user to post stuff to real Friends and then introduce a new feed page. The Home feed for friends and groups and a new for the follows feed. What would a good name be? News, The Fediverse, The world_
Option 2 - No follows only friends
Remote the follows concept all together. Users must jump to Mastodon or other to follow the rest of the world.
I'm leaning towards option 1. I still like to be able for a user to share someting from The world with friends.
What do you think - I like to be inspirred!

@leffe @jon_bon @leanderlindahl Som det er nu skal nye medlemmer godkendes. Det er et bevist valg for at undgå at gå lidt forsigtigt frem.
Fedibooks målgruppe er venner og grupper der arbejde sammen i et fællesskab. Ikke en stor debatforum. Det er der masser af andre løsninger til.
Når man skriver til gruppen står man selv som afsender. Du skal ikke indtaste noget brugernav og password for at være medlem af en gruppe. Hvis du vil oprette en gruppe skal du være bruger på en fedibook instans - men den kan du jo eventuelt drive selv eller sammen med nogle du har tillid til
At være bruger på en online tjeneste er en tillidssag - For fedibook er koden open source så du eller andre kan lave review og du kan vælge en udbyder du har tillid til.

Hi @julian thank for reaching out and good to see you in the meeting just now. I'm very new to this world so trying to understand all the concepts. I don't know if I solved it yet. At least I'm now able to include the author in the group message when seen on mastodon. I will post an update in the weekend with the status for this week.
@helo-grp@fedibook.dk test (sorry)

@madsenandersc@social.vivaldi.net great concept. How about friend and group in the same feed (tab). That is how Facebook does it right? - as fare as I recall.

Er det bare mig eller er disse super vigtige emner ikke rigtigt så interessante i disse dage. Jeg kan vælge at gøre noget ved grise, den grønne omstilling, drikkevand, formueskat - men hvad med Digital Suverænitet - hvem vil for alvor gøre noget?
Replying to
@arildsen The goal is to make it more simpel to use, install and look like something many will reconize right away. It not that different from Friendica - but perhaps more active and modern looking.

@leanderlindahl Goodmoring - Approved - please understand that this is very earlydays - Welcome.

@jens a docker host and with a proxy. It will come with a traefik container ready to you or your can use your own. I dont know performance requirements yet, but I a'm for it to be low. Right now running in 8GB host also running ghost,peertube,wordpress etc.

@madsenandersc Your are free to sign up at dev1.fedibook.dk or dev2.fedibook.dk but do understand that it is a playground and a peek into my dev system. Planning to deploy a demo env in the following week.

@julian This is what you mean right. This message should come from me and not the group?
I have spent the last long nights getting the Fedibook group feature proper working - A lot is working now.
