After reading about a major #Funkwhale instance shutting down, I'm wondering whether I should keep my podcast on open.audio.

https://blog.liberta.vip/libertadmin/its-over-for-liberta-audio

However, the idea of an audio app that uses #ActivityPub to be part of the #Fediverse is excellent.

Any suggestions on where to host a #podcast?

P. S. I just discovered @CastopodCastopod , an alternative to @funkwhale

I want to inspect which one is more stable, and if there are good servers as well. Feedback welcome!

Gibt es eigentlich Plugins um sich seinen #ActivityPub Feed in einem eMail-Client wie #thunderbird anzuzeigen?

So ne Standard-Funktionalität wie Posts in Unterverzeichnisse zu sortieren oder Gelesenes auszublenden würde mir schon viel helfen.

#fediverse #activitypub #wordpress

Fun idea, a #e621 like imageboard with #ActivityPub protocol slapped on top of it.

Back to @captaincalliope.blueLyre Calliope's original pointsin this thread:

I want a new flagship #atproto app that isn't a Twitter clone on the surface.

Indeed -- Rudy Fraser talked a lot about this in his ATmosphereConf presentation. And the same is true here in fedi, where Mastodon is still dominant. I think of this in a couple dimensions

• getting beyond microblogging, but still skeumorphic to well-known centralized systems (Pixelfed and Lemmy here; Flashes, Skylight, and Streamplace in the ATmosphere). If done well, that's valiuable in terms of getting people to the ecosystem (from an activism perspective, the lack of a skeumorphic approximation to Facebook groups is a huge barrier) but my guess this is still likely to have somewhat limited impact. When was the last time when a better skeumorphic app ever really caught on and displaced an incumbent>

• less-skeumorphic software is where it really gets exciting. There's a lot of momentum here -- Bonfire, Bandwagon, Piefed are three good examples here in fedi, the stuff Blacksky is working in the ATmosphere -- but it's very hard to predict what will and won't catch on.

"I also want to see #activitypub get some of the primitives that #atproto has such as decentralized identifiers (except for real), personal data stores, content addresses, etc.

I want to see both protocols cross-pollinate with each other's strengths. And perhaps share infrastructure like identities."

Yeah, totally agree. I think t here's been some cross-pollination in both directions (Blacksky's local-only posts were directly inspired by Hometown, Mastodon's FASP and Fedisovery are somewhat influenced by AT's Relay-based architecture) but there's certainly a lot of room for improvement.

Successfully imported a #Mastodon archive into my #Wordpress blog with #ActivityPub plugin's Importer. Yay! One down, two to go...

@nathan @davidrevoy @dansup @indexBuilding ActivityPub @AffektJake @ploum

My opinion re: #ActivityPub compliance is that any #FOSS project is free to implement AS/AP in any way they want, with any level of #compatibility.

#Compliance is absolute best-practice, but a project has full choice here. It's all FOSS freedom. No blame should be put towards these projects where they follow their own path.

Highly encouraging compliance is among the duties of the Grassroots standardization process that exists in the ecosystem.

@glecharlesGuy LeCharles Gonzalez

#ActivityPub is a generalized protocol specification

#Mastodon is a specific implementation of the generalized protocol

In Mastodon distros >4.5.x it's possible for users to specify (and limit) the range of people/accounts that can quote their posts

See: Settings --> Preferences --> Posting defaults: "Who can quote"

And note: Mastodon, not Wordpress

@nathan @davidrevoy @dansup @indexBuilding ActivityPub @AffektJake

There's mention of 'respect for the protocol', but given the inherent flexibility of #ActivityPub we can say that the protocol is respectful of many interpretations. The respect @ploum asks for, boils down to current informal consensus for interoperability, which in turn is to large extent Mastodon's interpretation.

It is a pity that fedi is so app-centric, but each apps choices are valid. The protocol needs better grassroots standardization process.

Any idea what this means?

I don't see anything in the ActivityPub plugin to approve individual interactions, and it doesn't appear to be integrated with the regular Comments feature.

#FediTips #ActivityPub #WordPress

„Is Pixelfed sawing off the branch that the Fediverse is sitting on?“

Interesting article but I disagree with the premise:
The #ActivityPub protocol does not demand to display all messages.
Actually, it doesn’t make any sense even.

When I use #Pixelfed, I do that to see pictures only. That’s the whole point.
If I want to see more, I have to use a more generic platform, like #Mastodon.

"sharedInbox endpoints SHOULD also be publicly readable OrderedCollection objects containing objects addressed to the Public special collection..."
https://www.w3.org/TR/activitypub/#sharedInbox

I disagree with this SHOULD, would downgrade to a MAY.

Minor, mainly because consider a small instance, whose users do not show their Following collections, this could basically leak who the follows are.

That said, I haven't found any Software that does have a publicly readable sharedInbox!

#ActivityPub

I see quite some posts on the topic of #monetisation on the #Fediverse. My opinion, in its simplest form, is that #ActivityPub connects people. In open, transparent and, yes, free ways. Think of AP as TCP/IP, but for people

With that in mind, note that TCP/IP itself has no features for monetisation. That is done on top of the protocol. This is how I would like to see monetisation in the fediverse too. As a separate thing on top of AP, never as inherent part of AP. My 2 cents (pun intended)

1/3

I think I have identified a fairly significant flaw in how the #Fediverse currently operates. Hear me out.

The Fediverse currently consists of all sorts of different systems - #Mastodon, #Friendica , #Pixelfed , #PeerTube, #BookWyrm , and so forth. And while they are all connected via the #ActivityPub protocol, they all have different functionalities and different ways of presenting themselves. Which is as it should be, because Diversity Is Our Strength(TM).

However, it is here that the ActivityPub-based interactivity hits its limits - for usually, you can either experience the relevant system as it was intended, or you can interact with it, but not both - _unless_ you have an account on the same system (though not necessarily on the same instance).

Let's say that you are a Mastodon user who looks at another person's BookWyrm page. You scroll through their books, posts, and comments. Then you see some comment you want to comment on yourself, but can you do so?

Not directly. You need to figure out the URL of their comment, and then copy and paste that comment into the search bar of your Mastodon instance. Then it will show up in the same format as a Mastodon post, and you can interact with it - boost it, like it, comment on it.

Sure, it works, but it's a whole lot of tedious effort.

Or you can search for the user account in Mastodon and scroll through all their posts and comments as if they were a Mastodon user - and thus, you will miss out on all the unique user interface features of BookWyrm.

So what is missing?

Well, Mastodon already has an "Open original page" feature when looking at someone's post. What we need is an "Open original page AND AUTHENTICATE" feature. This way, the target instance (whatever software they are using) could acknowledge the viewer as an external user who could nevertheless fully interact with the local user interface, including the ability to boost, like, and make comments.

This is something that should be theoretically possible to implement, right? #FediHelp

Has anyone evaluated headless #activityPub servers? I'm thinking of something that could be used with Ghost subscriptions giving posting access to a site forum and blog comments. I suppose it doesn't have to be truly headless as long as there's some sort of authentication API.

Are there any combination #ActivityPub servers and #ATProto PDSs?
So one can post on both networks simultaneously?

@niklaskorz

I keep track of #ActivityPub based #calendar and #event applications on the delightful #fediverse experience curated list. See:

https://delightful.coding.social/delightful-fediverse-experience/#events-planning

There are a couple of apps that have fediverse support on the roadmap. And a new very interesting candidate to add to that list. See #Lauti:

https://lauti.org

https://codeberg.org/Klasse-Methode/lauti

#Eventbrite to be acquired by #BendingSpoons, following their acquisition of #Meetup.com which caused many users to migrate to Eventbrite in the first place. I think at this point it becomes very obvious that the #Fediverse is the best place to coordinate your meetups, and you have many options to choose from: #Mobilizon, #Gancio and even #Wordpress with the #ActivityPub Event Bridge plugin. Everyone knows Bending Spoon's playbook, enshittification is inevitable.

I also want to see #activitypub get some of the primitives that #atproto has such as decentralized identifiers (except for real), personal data stores, content addresses, etc. I want to see both protocols cross-pollinate with each other's strengths. And perhaps share infrastructure like identities.

End-to-end Encryption (E2EE) over ActivityPub

Encrypted direct messages supply the confidence that people need to connect with family, friends and colleagues privately over a social network. As part of the Summer of Protocols 2024, we explore the integration of end-to-end encryption (E2EE) into the ActivityPub protocol.

#supportrotation

BotKitは、ActivityPubボットを作るためのTypeScriptフレームワークです。既存のMastodon/Misskeyボットとの違いは、ボット自体が独立したサーバーとして動作すること。プラットフォームのアカウントは不要です。

文字数制限もなければ、APIレート制限に悩まされることもありません。

bot.onMention = async (session, message) => {
  await message.reply(text`こんにちは、${message.actor}さん！`);
};

フェデレーション、HTTP Signatures、配送キューといったActivityPub周りの処理はFedifyがすべて引き受けます。ボットのロジックを書くだけです。

DenoでもNode.jsでも動きます。

https://botkit.fedify.dev/

#BotKit #Fedify #ActivityPub #TypeScript #Deno #NodeJS

BotKit은 ActivityPub 봇을 만드는 #TypeScript 프레임워크입니다. 일반적인 Mastodon/Misskey 봇과 다른 점은, 봇 자체가 독립된 서버로 돌아간다는 겁니다. 플랫폼 계정이 필요 없습니다.

글자 수 제한도 없고, API 호출 제한에 시달릴 일도 없습니다.

bot.onMention = async (session, message) => {
  await message.reply(text`안녕하세요, ${message.actor}님!`);
};

연합(federation), HTTP Signatures, 메시지 전달 같은 #ActivityPub 관련 처리는 Fedify가 알아서 해줍니다. 봇 로직만 짜면 되는 거죠.

#Deno 및 #Node.js 둘 다 지원합니다.

https://botkit.fedify.dev/

#BotKit #Fedify

#BotKit is a #TypeScript framework for building #ActivityPub bots. The difference from typical Mastodon/Misskey bots? Your bot runs as its own independent server—no platform account needed.

This means no character limits, no rate limiting headaches, no API restrictions.

bot.onMention = async (session, message) => {
  await message.reply(text`Hi, ${message.actor}!`);
};

The ActivityPub stuff (federation, HTTP Signatures, delivery queues) is handled by #Fedify under the hood. You just write your bot logic.

Works with both #Deno and #Node.js.

https://botkit.fedify.dev/

I have a question for #ActivityPub fanatics. For the Social Web Devroom at FOSDEM 2026, we've reached out to over 50 different Fediverse projects to make sure they know about the event. Is there anyone else we need to reach? If you know someone working on Fediverse software development OR organisational and social issues, please share this call-for-proposals link. Our deadline is Dec 1, 2025 and we don't want to miss any part of this movement.

I've streamlined theme development in Ktistec. The theming system uses a hierarchy of CSS custom properties and fallbacks. Theme authors can customize a theme at multiple levels:

Base Colors Only

Define only base colors like --text-primary, --bg-primary, --bg-input, --semantic-primary, etc. Derived colors will auto-generate using color-mix formulas. For example:

:root { --semantic-primary: #ffa500; }

From this one line, theme-appropriate colors like --bg-accent-code, --anchor-color, etc. auto-generate.

Base Colors Plus Derived Colors

Define base colors and derived colors. Derived colors use custom values when defined. Undefined derived colors auto-generate. For example:

:root {
    --text-primary: #333;
    --text-primary-2: #ff0000;  /* red for this specific shade */
}

Given this theme, derived shades like --text-primary-1, --text-primary-3, and --text-primary-4 auto-generate. --text-primary-2 is red.

The simplest possible interesting theme redefines the primary semantic color. The single line above (in Base Colors Only) would result in the following, with button color, link color, disabled, selected, and hover states all derived automatically:

These changes will be in the upcoming release. Existing themes will continue to work, as is.

Loops has a poor mobile web UI.

So I spent the past 6 hours refactoring it to better match our mobile app layout, while keeping it consistent, and improving the desktop layout too.

You don't need to install an app to enjoy Loops, and we will be implementing proper PWA support with Push Notifications and better Offline mode.

Hey #fediverse, is there an activitypub application similar to meetup? I would really like to add a trail ride planning platform to Dirt Social and i'm curious if something already exists.

I thought i remembered seeing one somewhere. but i can't find it now.

Thanks!

#mastoadmin #activitypub

My experimental #ActivityPub #SolidProject agent now listens to POSTs to a list of inboxes and outboxes and processes activities asynchronously as they arrive.

Next I plan to dynamically define the inboxes and outboxes.

The agent would be given access to a config, subscribe to the listed topics and connect them to the appropriate handler.
It would also set the public key on the named actor. e.g.

:myactor_inbox a :WebHookRegistration;
:topic </inbox/>;
:handler :InboxModified;
:actor </actor>.
