#ActivityPub #c2s #ActivityPubAPI #Fediverse

#FediHood should be easy to use, with a very simple interface. It fully uses #ActivityPub and is compatible with the #Mastodon API (tested with #Fedilab). It will of course bring extra endpoints related to how it works. The project reuses the combined work from #HolosSocial and #PawFed.

Here are some screenshots of the Web UI.

Alt...

FediHood's map set to an 8 km radius: an interactive map showing two count badges, each marking how many people are in that spot.

Alt...

FediHood's Nearby feed: a distance slider set to 10 km, then a few posts from people close by, each with a time, a city, a distance and a topic tag such as Sport or Events.

Alt...

FediHood's compose screen: a large message box, then four options: Visibility (who can see the post), Reach (how far it shows in Discover), Topic (its category) and Language (what you write in), plus Add image and Publish buttons.

Alt...

The topic list in FediHood: Chat, Meet people, Events, Help, Buy & sell, Transport, Local news, Politics, Sport and Culture.

Great day at #Fedicon yesterday. I met lots of new people from the #ActivityPub community. I've always thought that #XMPP and the #Fediverse are ideologically well-aligned, and that our developer communities should talk to each other more. In that regard, it was a big success.

Stefano Marinelli (creator of the excellent FediMeteo) is working on a new type of lightweight Fediverse server called "littleFedi".

It's still in its early days and under development, but the first test server is now open and Stefano is gathering feedback about it. More info in the quoted post at https://littleone.littlefedi.social/@stefano/a105002b-5749-437d-a3cd-da54dfa70395 and more detail at https://littleone.littlefedi.social/@stefano/4252ae6f-b949-42f8-a021-fd2b698f8b37

Stefano Marinelli - littleFedi » 🌐 2026-08-05
@stefano@littleone.littlefedi.social

Hi everyone, I'm Stefano

Also known as the BSD Cafe and illumos Cafe barista - @stefano@bsd.cafe and @stefano@illumos.cafe

This is the first post from littleOne (littleone.littlefedi.social), the first littleFedi instance open to outside users.

littleFedi is a new ActivityPub server, still in active development, written in Go and shipped as a single binary. It speaks standard ActivityPub, so it federates normally with Mastodon, snac, GoToSocial, Akkoma and the rest of the fediverse, and it exposes a Mastodon-compatible API, so most existing apps already work with it.

A few things about it that aren't the usual fediverse defaults:

• Catch-up instead of an algorithm. Timelines stay chronological, full stop. There's a separate /catchup page, visited on demand, that ranks what you missed using only signals this instance already has locally - who you follow boosted it, replies and favourites delivered here, hashtags you follow. No external popularity data comes in, nothing about what you read is tracked. It answers "what did I miss" without turning into a feed that decides for you.

• Static blogging built in. Any post can be marked as a blog post and gets published as a plain static page under /@username/blog/, with its own permalink, Atom feed, and no JavaScript or database hit per view, while still being a normal federated post underneath. A proper home for longer writing that doesn't need to compete with a timeline.

• Self-expiring posts. Any post can be given a timer and auto-delete on its own.

• Bubble timeline. A middle ground between local and federated: a timeline scoped to a set of instances you've chosen to group together, not just your own or everything.

• littleMesh. A way to federate without a public domain, certificate, or open port at all - meant for something like a Raspberry Pi behind NAT. Instances get an address derived from an Ed25519 key pair and reach each other through pinned relays that never see plaintext.

• No trends, no suggestions. These are intentionally left empty. Nothing here is trying to surface "popular" content or keep anyone scrolling longer.

• Security defaults taken seriously. Signed federation (HTTP Signatures), optional Object Integrity Proofs, TOTP MFA, audit logs, and full account export, migration and deletion if you ever want your data to live somewhere else.

This instance is here to test all of that with real accounts, not just a small group ones'. In the next few days I'll be reaching out to everyone who already told me they were interested, to set the first accounts up - an invite is coming. If you'd rather just follow along and see how it goes, that works too.

It's a test instance, so expect the occasional rough edge. If something breaks or feels wrong, tell me - that's exactly what this phase is for.

Five of Indonesia’s most powerful security officials declared the country secure while malls were fenced, unfenced, and a woman was arrested for a Facebook post. Eleven days before Independence Day, the government is managing memory to protect extraction and punish warning. That same government moved fast enough to make a dictator a national hero within a year of taking office; it has never moved that fast for anyone’s survival, anywhere.

🆕 blog! “Some updates to ActivityBot”

I couple of years ago, I developed ActivityBot - the simplest way to build Mastodon Bots. It is a single PHP file which can run an entire ActivityPub server and it is less than 80KB.

Previous edition: https://mitra.social/objects/019fba46-e7be-7ee0-ae8b-8a2a8daec431

Okay, so

https://docs.joinmastodon.org/spec/security/

According to resources linked in the #Mastodon docs, it seems that signature validation gets the entire #ActivityPub Actor (thus the `#main-key` which the server is supposed to ignore) and then within the Actor it gets the `publicKey` property.

Soooo back to the `#main-key` nomenclature, I guess

#snac2 #fediverse #frugalfediverse

The author of a replied post is no longer added to the CC: line, as it does not have much sense.

Fixed mentions for users with hyphens in their identifiers.

Unlisted replies to unknown posts were being skipped from the timeline, so don't do that.

If an actor marked as broken gets a post boosted (proving that is [back] functioning), it's unmarked as such.

Don't try (and fail) to parse non-UTC dates in posts (I'll provide a real fix eventually).

Fixed a redirection loop in the /users alias.

Mastodon API: fixed a bug that made changing the sensitive content string impossible, avatars and headers can be deleted (contributed by bm90).

Updated Czech and Italian translations (contributed by pmjv and fidiben).

I migrated from my self-hosted Mastodon instance to mastodon.social. Of course, I couldn't move my posts so I created a small server to provide the archive of my post history without changing any #ActivityPub URIs or media URLs. It seems to be working well. RAM usage is down from 1.2GB to 45MB (-97%) and disk usage down from 160GB to 15MB (-99.99% drop) compared to keeping the old server running. I've been surprised how many "hits" I'm seeing for old posts, so I'm glad the archive is available.

Turns out, #Mastodon 's implementation of #ActivityPub just has eveything in a Note's content and contentMap be HTML, so Markdown gets transcribed into <h*>, <strong>, <em>, <code>, etc.

But also, OPTIONALLY, some of those HTML Note also have a mediaType property with value "text/html" so maybe you can make an untranscribed markdown Note if you specify "text/markdown" maybe?

Inconclusive.

I'm looking for a freelancer or org who can help me set two Ghost instances in one virtual server, with ActivityPub. Only setting up the instances and the server, I can handle the web administration.

I'm almost there with the first instance but at every step there is something, I'm not a sysadmin, and I'm losing my patience. 😅 I bet this is straightforward for someone with experience.

I can give you more details -- and see https://the.socialmusic.network/t/a-music-selection-idea-welcomes-your-feedback/854

Seeking beta testers for a new opt-in Fediverse service - FediAdhan
https://fediadhan.org/

Have you ever felt your #Mastodon timeline was missing something? You get regular updates about the weather, the bongs of Big Ben on the hour; perhaps even that one account that toots like a chicken. But you've been missing timely updates about the Islamic call to prayer.

No longer: with FediAdhan, simply pick your location on the map and you'll get an account you can follow from your #ActivityPub client, which will drop a toot in your timeline when any of the five Islamic prayer times rolls around (and optionally for sunrise as well). And you get a neat pie chart of daylight/twilight for your location, as a bonus.

Explicitly opt-in, privacy focused, #HumanMade with no LLMs used at any stage in development. Try it out, let me know if you have thoughts, feedback, issues you run into.

Erst W, jetzt "Eurosky" - warum?
Es gibt doch schon ActivityPub und das Fediverse, wieso noch was neues entwickeln?

Implementing your own #Fediverse #ActivityPub server sounds like a good idea until you see the mush of half-implemented protocols that #Mastodon actually is. #ActivityStreams Link type? Profile? Tombstone? Whomst?

Why is there a webfinger endpoint? I don't want skeletal twinks fingering my web!?

And also an RSA key pair? Publicly being this embarrassing should be proof enough, nobody would dare pretend to be *this*!

We could table for #mastodon (the #activitypub platform) outside of the Mastodon (the #metal band) show. There could be swag. The #heavyMetal fans would be so confused but the subset of them that are also into #FOSS would be embarrassed for us but also would secretly cherish the chaotic energy. This is a terrible idea, which is why we must #bostodon #boston

I added a list of recommended libraries to the ActivityPub developer guide:

https://codeberg.org/ap-next/ap-next/src/branch/main/guide.md#libraries

- activity (Go, used in GoToSocial)
- Fedify (JavaScript, used in Hollo and Ghost)
- Fedipub (Ruby, used in Manyfold)
- activitypub_federation (Rust, used in Lemmy)
- APx (Rust, used in Mitra)

This list only includes libraries that are actually used somewhere. Libraries that are not used, or used in projects with too few users are not included.

#fedidev #activitypub

Welcome to Prismo revived!

Not so long ago, after a bit of encouraging from @dansup, I decided to revive this project using more modern stack. Apart from it being more modern, it is also way lighter than before and that's my main goal when working on it: everything should be as simple, light and independent as possible.

Technical stuff

New Prismo only depends on Ruby and sqlite. JS layer is minimal and based on importmaps so no heavy build step is needed anymore. CSS is being generated by native tailwind binary so produced stylesheet files are as small as possible and generation footprint is tiny.

When it comes to federation, old Prismo was based on a code extracted from Mastodon which was both messy and far from optimal to be used by such a small and simple website. Now we're using an excellent ruby library called Fedipub instead.

Why another link aggregator?

While other projects are focused on supporting multiple groups with massive amount of people in them, Prismo is more about small cozy federated single-topic instances. Being small and simple will let us perfect our feature set more easily.

What's next?

There is no any roadmap as of yet but, for starters, i will try to bring back original feature set (as you might feel like new Prismo is a downgrade from the old one - i just brought back the essentials for now). After that - we can discuss on what's needed and what would be good to have :)

There are obviously plenty of rough edges and issues but we will get there eventually. Let me know in the comments and, as usual, boosts highly welcome! :)

Let's talk!

• Mastodon
• Matrix

The network effect is crucial to every social platform, and what differentiates them is how they are able to match IRL connections with online ones, and we can do this, but it needs to be done carefully and in a way that preserves privacy and user autonomy across platforms and services.

No single software should have the ability to wall off access, or we become the thing we worked so hard to replace.

More details soon 👀

#ActivityPub #Discovery #FriendFinder

One boost.

40k followers.

Thousands of individual HTTP requests, each one signed, each one a fresh connection, each one saying hey to a server it talked to four milliseconds ago.

Mastodon, Pixelfed and Loops do better than most here.

We can still do significantly better.

What if two servers just... stayed on the line?

More details soon.

#ActivityPub

@dansup

A good feeling, hopefully?

#ActivityPub #SocialWeb #Fediverse #AtProto

In 1968 Dijkstra declared GOTO statements harmful.

In 2021 someone built them an entire social network anyway.

GotoSocial is a lightweight #ActivityPub server that can run on a potato, blocks scrapers by default, and with privacy defaults that would get a product manager fired at any real company.

Now it's one of the fastest growing on the fediverse.

Built by @dumpsterqueer under the name Super Serious Business, which is the most honest branding in tech right now.

https://gotosocial.org

It's a strange feeling, building something with no one to answer to but the people using it.

No walls to raise. No data to harvest. No quarter to hit.

Just a network of communities that actually belong to the people in them.

Happy to announce that federation bit is complete! Next step is purchasing a domain and spinning up a flagship instance which should happen in upcoming days :)

#fediverse #fedidev #activitypub #prismodev

I look forward to working with @benpate, @Bonfire and @evan from the SWF on E2EE Direct Messages in Loops, Pixelfed and Sup!

They’re doing some amazing work, and it makes a lot of sense to collaborate and widen compatibility across our platforms!

#ActivityPub #E2EE

Hello, and happy summer to you all.
Cookifed is an Open Source and federated recipe notebook and baking tracker.

Using us, you can keep track of your favorite recipes, plan when you can to cook/bake them, and keep track of each preparation/change you made in the recipe to get better next time.
We are federated over ActivityPub. So you can also share your recipes and bakings with anyone on the fediverse.

#cookifed #Fediverse #ActivityPub #cooking

The thing about the fediverse is that when one of us wins, we all win.

I couldn't be more proud to work alongside so many talented people who share the same belief: together we're stronger, and there's so much more we can build.

The corporate platforms had a decade and billions of dollars on us. They still can't build the one thing we did: a network nobody owns, nobody can sell, and nobody can take away.

A social home for the people. By the people.

❤️

#ActivityPub #Fediverse #SocialWeb

Today is announcement day 🔥

Bonfire is shifting its centre of gravity: from social features to community tools. Four things ship today, and the whole story is here: bonfirenetworks.org/posts/bo...

1. Bonfire for communities
Groups and topics, community rules, decision-making (from quick polls through structured consensus to weighted score voting, where an objection can count for more than an approval), events, shared organisation profiles, announcements.

A ready-to-use space you can then take apart: add what's missing, fork what almost fits, switch off what you don't need.

2. Our first Mosaic case study
Six months with Jacobin's German edition, building jacobin.social from the ground up: a home for 3,000+ readers, wired into their Ghost publication, in their language and their look and feel. Their readers crowdfunded the project, which included a reboot of the magazine and a new community space. Now every publisher can benefit. What one community funds, every community inherits. Details: bonfirenetworks.org/case-stu...

3. A deep Ghost integration
Keep publishing exactly as you do now, and Bonfire can become the home for everything that happens around the work: your archive imported, new articles followed, members and tiers synced, sign-in through Ghost, federated discussion under every piece. Details: bonfirenetworks.org/ghost/

4. The Telling
One script tag turns any web page into a federated conversation. Readers reply with an account they already have, on Bonfire, Mastodon, anywhere. The thread lives on your server, and you can take it with you. Details: bonfirenetworks.org/telling/

Being straight with you: this is a 1.0 beta. Groups work within a server and don't federate yet. We're designing that in the open with the W3C groups task force, because we'd rather it work across the whole fediverse than ship a dialect only Bonfire speaks.

Want to poke at it? Groups are live on the campground, our open test instance. Make an account and try it out: campground.bonfire.cafe

Finally, we've rebuilt the website to reflect the new direction: bonfirenetworks.org/

Now back to following up with crowdfunding backers to organise install parties, co-design workshops, and other rewards. Thank you for your patience 💛 #fediverse #ActivityPub

We are so proud of @dansup for being the only #ActivityPub developer to be accepted into the Sovereign Tech Standards cohort.

You've seen what he's done with Pixelfed, Loops, Fediverse.info and FediDB.

Just imagine what he can do for #ActivityPub standards work, having two major platforms that can steward and solve problems at scale and in the real world 🔥

https://www.sovereign.tech/news/meet-the-first-sovereign-tech-standards-cohort

Honored to be one of ten maintainers in the first @sovtechfund standards cohort.

I'll be representing #ActivityPub and the #fediverse at the w3c, bringing eight years of running Pixelfed and Loops at scale into the room where the spec gets written.

https://www.sovereign.tech/news/meet-the-first-sovereign-tech-standards-cohort

#SovereignTech

If there are any other #fediverse developers working on a TikTok like platform for the fediverse:

Maybe we can join forces and work together with Loops, and if not, lets keep in touch so we can work on #activitypub compatibility?

I'm already working closely with @stux on #Goldfish, which is shaping up to be a serious fedi TikTok contender!

#strongerTogether

@liaizon #Bridgy is the incumbent on the #ActivityPub / #ATProto bridging front, and currently the only "production grade" system available to te general user, right ?

Hashtag following also allow URLs to RSS feeds of ActivityPub objects (like e.g. https://mastodon.social/tags/ThankYouTuesday).

Users can now configure a webhook to receive an HTTP POST for every notification. This can be useful for implementing bots that react to activities, like autorepliers, chatbots or interactive textual games (see snac(1) for more information).

The number of pending follow confirmations is shown next to the "people" link.

Faster performance metrics (contributed by dandelions).

Improved lowercasing in hashtags (contributed by postscriptum).

A search-by-url tweak for implementations that return 200 for invalid webfinger queries (e.g. piefed).

Mastodon API: added follow confirmation endpoints, fixed collisions in attachment file names.

Fixed potential crashes in attachment uploads.

Notifications are now shown in a more compact way (i.e. all reactions are shown just above your post, instead of repeating the post ad nauseam for every reaction).

New command-line option unmute to, well, no-longer-mute an actor.

The private timeline now includes an approximate mark between new posts and "already seen" ones.

Fixed a spurious 404 error in the instance root URL for some configurations.
