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:

#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.

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>.

Stegodon v1.3.0 is out. Massive performance improvements!

In a wide-ranging interview with @GargronEugen Rochko, creator of the decentralized social network @Mastodon, Rochko shared why Threads federation fell flat, why #ActivityPub and #ATProto will likely never merge, and what it will take to grow the #Fediverse.

Could I ask #fediverse for some #fedihelp? What is currently best technical solution for writing a #blog where each blog post is an #ActivityPub message that is fully displayed on Mastodon? Last time I tried the #wordpress #integration #plugin, only links to the blogposts were displayed on Mastodon.

The ideal solution would actually be some integration with #quarto so I can flexibly integrate the blog in my page but other solutiona are just as welcome. Thank you in advance!

I've proposed two possible outlines for a document about #SolidProject #Activitypub integration

https://github.com/solid-contrib/activitypub-interop/issues/2#issuecomment-3590595603

The first is more note/tutorial/primer like, because a large part of the content is just redescribing ActivityPub for a Solid audience.

The second assumes prior knowledge of ActivityPub and primarily describes what is needed to integrate ActivityPub with Solid, based on three architectures:

- Server support
- External processing
- External endpoints

Experimenting with x-ray mode for ktistec.

A while back I mentioned the idea of “Fedify Studio”—a web-based toolkit for #ActivityPub debugging and development. I've been quietly working on shaping that idea into something more concrete.

Nothing to announce yet, but it's looking like this might become a team effort rather than a solo project, which would be nice. We'll see how it goes.

#Fedify #fedidev #fediverse

I am looking for a tutorial about #activitypub for beginer

any links or advice welcome

I plan something very simple in #php

Eurosky dawns: Building Infrastructure for Sovereign Social Media – Open Future

Not sure how to take this: Mastodon already exists, it’s a European project and it’s struggling to take off.

I don’t think that the problem with Mastodon’s lack of adoption is the ActivityPub protocol. What advantages does the ATProtocol have that will lead to wider adoption?

developing alternative social media infrastructure that is not controlled by Big Tech or venture capital-backed US corporations, anchored within EU jurisdiction, and designed to foster a more pluralistic information ecosystem.

Short video isn't the villain, it’s just how we share our lives today. More people are capturing and sharing raw, human moments than ever before, and that’s beautiful ✨

The problem isn't the format; it's the surveillance and toxicity built into the big platforms.

We’re trying to keep the joy (sharing + remixing + community) and ditch the stuff that harms people (manipulative feeds, creepy tracking, lock-in).

In case you missed it, we released a new version of Surf last week, with a redesigned Home. Here are a few cool new Surf feeds to celebrate (and to keep you occupied if you're enjoying a few days off for the U.S. Thanksgiving holiday).

Fun fact: I bought my own social network at around the same time Elon bought his.

#Mastodon #ActivityPub

I have a side project baking app for which I'm adding federation. I'm pretty far from full #ActivityPub implementation (it's a side project), but I'm pretty excited about the potential.
Should I present it at #FOSDEM anyway?

What Is The Fediverse?

If you’re not familiar with the name “#Fediverse” – that’s okay. It is is an open society of web services that is already serving millions of people all around the world. They do this through a common language called #ActivityPub that lets news and events flow from one site to the next. So, instead of checking in to 5 or 6 different corporate sites, you can find, follow, like, and share across many, many sources – all from your own, singluar Fediverse profile.

Does anyone else have this issue with their Ghost 6.9.0 blog?

I can write posts, I can follow other people, but the explore tab is completely empty and even when I follow other accounts, I cannot read their messages in the "Reader" section.

No matter if I try to use "top" or any other topic. I always get a "404". ActivityPub initialization seems to be fine though.

What am I missing? (yes, the domain name is redacted)

Collections are the most under-specified entities in #ActivityPub. I've started documenting them in a FEP:
