There we go. #Snac2 up and running with the preferred installation process. Added custom styling to boot. One confusion point with styling is that it does NOT affect the root page (greeting.html) only the profile pages. So I thought I had done something wrong, but finally figured it out.

ActivityPub object identifiers are not IRIs. They are URIs:
https://www.w3.org/TR/activitypub/#obj-id
Unicode characters are not allowed there.
After reviewing FEP-5624: Per-object reply control policies and GoToSocial's interaction policy spec, I find myself leaning toward the latter for long-term considerations, though both have merit.
FEP-5624 is admirably focused and simpler to implement, which I appreciate. However, #GoToSocial's approach seems to offer some architectural advantages:
The three-tier permission model (allow/require approval/deny) feels more flexible than binary allow/deny
Separating approval objects from interactions appears more secure against forgery
The explicit handling of edge cases (mentioned users, post authors) provides clearer semantics
The extensible framework allows for handling diverse interaction types, not just replies
I wonder if creating an #FEP that extracts GoToSocial's interaction policy design into a standalone standard might be worthwhile. It could potentially serve as a more comprehensive foundation for access control in #ActivityPub.
This is merely my initial impression though. I'd be curious to hear other developers' perspectives on these approaches.

With just 32 hours left to go...I can't believe it...they are less than $500 away from meeting the $55k goal, which will add in-app live streaming capabilities.
Let's make this happen. 💪🏼
<p>We’re excited to share this roadmap — there’s a lot happening with the ActivityPub plugin, and we can’t wait to show you what’s coming next.</p>
<p>We often refer to this roadmap in GitHub issues and discussions, but until now, we haven’t published a full roadmap post — nor a formal changelog. This post is a first step toward keeping the community more informed about what’s planned and what’s coming up next.</p>
<p>Our goal for this year is to finalize the full ActivityPub experience […]</p>
I'm glad to announce the release of version 2.75 of #snac, the simple, minimalistic #ActivityPub instance server written in C. It includes the following changes:
Added support for scheduled posts (for this to work correctly, users will have to set their time zone, see below).
The user can now select a working time zone. This will be used to correctly parse the local date and time of a scheduled post.
Fixed incorrect poll vote format, which was causing problems in platforms like GotoSocial.
Mastodon API: added support for /api/v1/instance/peers.
Added a new snac-admin helper script (contributed by shtrophic).
In the web UI, posts are separated by the <hr hidden> tag; it's invisible in graphical browsers, but it separates post clearly in text-based browsers.
Some Finnish, Spanish, Czech and Russian translation updates and fixes.

I've been wrestling with implementing #multilingual content support in Hackers' Pub, our #ActivityPub-powered platform for software engineers.
While ActivityPub theoretically supports multilingual content through the contentMap property, the reality is that most server implementations (Mastodon, Misskey, etc.) don't properly handle this content as of April 2025. This creates a significant challenge for us.
We want our users to share their knowledge in multiple languages, but we need to ensure compatibility with existing ActivityPub servers. I'm considering several approaches:
Creating separate posts for each language with clear language indicators, linking them through inReplyTo relationships (so translations appear as replies to the original post)
Using the primary language in content while storing translations in contentMap
Adding "View in other languages" links at the bottom of each post
Implementing inline language dividers that degrade gracefully on non-supporting servers, for example:
<div lang="en"> <h3>English</h3> <p>This is the English content…</p></div><hr><div lang="ko"> <h3>한국어</h3> <p>한국어 내용입니다…</p></div>
I'm leaning toward a hybrid approach—showing content in the user's preferred language when possible while providing easy access to other language versions.
Has anyone tackled this problem effectively? I'd love to hear about your experiences or ideas for making multilingual content work well in the fediverse, especially when dealing with server implementations that don't fully support ActivityPub's multilingual features.
Fediverse Report #115 - This week's #fediverse news:
- @peertube launches v1 of their mobile apps
- @Mastodon shares more information on their team is growing
- @swf launches places.pub, a way to put OpenStreetMap data directly on #activitypub
I've been considering what to add in the next version of BotKit (v0.2.0) and wanted to share my current plans. After reviewing feedback and examining the #ActivityPub ecosystem, I've identified three key features that would significantly enhance the framework's capabilities:
Custom emoji support. This would allow bots to use server-defined custom emojis in their messages, making communication more expressive and allowing better integration with instance culture.
Emoji reactions. I plan to implement both sending and receiving emoji reactions to messages. This provides a lightweight interaction model that many users prefer for simple acknowledgments or responses. This would manifest as new event handlers (like Bot.onReaction) and methods (like Message.react()).
Quote posts. The ability to reference other posts with commentary is an important discourse feature in the fediverse. Supporting both sending quotes and detecting when bot posts have been quoted would enable more sophisticated conversational patterns.
These additions should make #BotKit more capable while maintaining its simple, developer-friendly API. I expect implementation to involve extending the Message class and adding new Text processing capabilities, all while keeping backward compatibility with existing bots. Having built both Hollo and Hackers' Pub, I already have deep familiarity with how various ActivityPub implementations handle these features across the fediverse. I welcome any community feedback on priorities or implementation details before I begin coding.
As someone who has developed several #ActivityPub software implementations (Fedify, Hollo, BotKit, and Hackers' Pub), I believe one of the most frustrating features to implement in the #fediverse is #custom_emoji.
The challenges are numerous:
First, there's no standardization. ActivityPub specifications don't define how custom emoji should work, leading to inconsistent implementations across different servers like Mastodon and Misskey.
Rendering is particularly problematic. Emojis must display properly across different contexts (in text, as reactions, in emoji pickers) while maintaining quality at various sizes. Animated emojis add another layer of complexity.
Perhaps most concerning is the poor #accessibility. Most implementations simply use the emoji code (like :party_blob:) as the alt text, which provides no meaningful information to screen reader users (in particular, non-English speakers) about what the emoji actually depicts or means.
What really dampens my motivation to implement this feature is knowing I'm investing significant effort into something that ultimately creates accessibility barriers. It's disheartening to work hard on a feature that excludes part of the community.
Just rolled out some fediverse-related improvements:
- Now you can follow Write.as blogs from Ghost! There was a tiny bug with this that we just fixed. (WriteFreely PR: https://writefreely.org/pull/1373)
- We now support the `preview` property as a fallback for Articles. This will make your posts look much nicer as more platforms support it! (WriteFreely PR: https://writefreely.org/pull/1374)

We're excited to introduce emoji reactions in the upcoming #BotKit 0.2.0 release!
With the new Message.react() method, your bot can now react to messages using standard Unicode #emojis:
await message.react(emoji`👍`);
#Custom_emoji support is also included, allowing your bot to react with server-specific emojis:
const emojis = bot.addCustomEmojis({ // Use a remote image URL: yesBlob: { url: "https://cdn3.emoji.gg/emojis/68238-yesblob.png", mediaType: "image/png", }, // Use a local image file: noBlob: { file: `${import.meta.dirname}/emojis/no_blob.png`, mediaType: "image/webp", },});await message.react(emojis.yesBlob);
Reactions can be removed using the AuthorizedReaction.unreact() method:
const reaction = await message.react(emoji`❤️`);await reaction.unreact();
Want to try these features now? You can install the development version from JSR today:
deno add jsr:@fedify/botkit@0.2.0-dev.84+c997c6a6
We're looking forward to seeing how your bots express themselves with this new feature!
I'm glad to announce the release of version 2.76 of #snac, the simple, minimalistic #ActivityPub instance server written in C. It includes the following changes:
Added Webmention support for links (Markdown-style or direct) written in a post.

Display custom emoji in more places (contributed by dandelions).
Mastodon API: fixed infinite scroll in many clients (thanks to cheeaun for giving me the clue), added /api/v1/accounts/.../lists endpoint (contributed by dandelions).
Email notifications can now be sent via libcurl SMTP instead of spawning the /usr/sbin/sendmail program. To use this new feature, some additional server configuration is needed, see snac(8) (contributed by shtrophic).
