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.

No movement whatsoever. I need $229 more to cover groceries for a month and $218 for meds. I need this ASAP.

Any amount helps. Sharing my request also goes a long way.

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

As of yesterday this instance is now pushing to the https://relay.toot.io #ActivityPub Relay

This should help spread @logisticsbot@social.eurybia.osx.ninja and @randomcomics a but further afield

My catch-all email address is getting spam emails for accounts on my self-hosted Mastodon instance. The spam scrappers must be confusing federation email-like user@instance account handles as email. #Mastodon #Spam #ActivityPub #Federation #MastoAdmin Anyone with a catch-all box seeing this? Interested if another instance with two or three dozen or more users on their instance is...

One of the best features of the open social web is the complete separation of backend protocol from mobile user interface.

On centralized platforms like X or Instagram, you're forced to use official ad-filled apps. In the Fediverse, your identity is yours, and you get to pick your ideal client! 📱

Here is a breakdown of the 5 best ActivityPub mobile apps in 2026:

1️⃣ Ivory (iOS & macOS): The gold standard from Tapbots. Unmatched fluid animations, custom tab layouts, and iCloud position sync.

2️⃣ Tusky (Android): 100% free and open-source. Extremely lightweight, fast, and battery-efficient with native Material design.

3️⃣ Ice Cubes (iOS & macOS): Fully open-source SwiftUI app with extensive feed customization, local timeline controls, and built-in AI translation tools.

4️⃣ Nootti (iOS): Lightweight client supporting custom reaction emojis, local posting, and multi-protocol accounts (ActivityPub, ATproto, Nostr).

5️⃣ OpenVibe (iOS & Android): Unified cross-protocol hub allowing you to view and cross-post across ActivityPub, Bluesky, and Nostr in a single timeline.

This has fixed/adjusted the certificate issue, and I have documented transfer of posts from my test nodebb -> friendica and nodebb->mastodon
and vice versa.

I'll let it run for another day or two, looking for more test subjects/connections and I'll push it to final barring any new issues.

#relay #fediverse #activitypub #relayservers

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!

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

All https://fedihost.co #Mastodon instances have been updated to v4.6.4

If you notice any issues please let us know.

@DeutscherWetterdienst fürher war Vimeo mal dabei, aber war jetzt seit Jahren schon nicht mehr auf der Seite.
Sonst benutze ich noch regelmäßig https://media.ccc.de/ vom @c3voc und https://media.freifunk.net/ von @freifunk, also was auf Basis von #voctoweb. (auch wenn voctoweb für euch zumindest alleine vermutlich eher uninteressant ist? leider kann voctoweb im Gegensatz zu #Peertube auch noch kein #ActivityPub / #Fediverse oder #WebRTC #P2P soweit ich weiß)

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

If you've been wanting to move your activity history from Strava to FitPub but dreaded dealing with the export files, I made a small browser tool that does the heavy lifting.

Drop in your Strava export files, it decompresses the .fit.gz files, splits everything into correctly-sized ZIP batches, and hands them back for upload. No install, no server, runs entirely in your browser.

👉 🏃🏻‍♀️ https://vast-ch.github.io/strava-archive-to-fitpub-batch-import/

Good morning Fedi friends,

I have been feeling a rising anxiety over the state of the open web and the fediverse - after seeing efforts by politicians all over the world (in Europe too!) to introduce age verification laws for social media.

My way of coping?

Teaching people how to self-host their own Fediverse profile (using the superb #GoToSocial) via #YunoHost.

Chapter 1 in this series is available here:

🔗 : https://blog.elenarossini.com/a-newbies-guide-to-self-hosting-gotosocial-part-1-installation-and-set-up/

#resist #blog #ActivityPub #selfhosting

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.
