<p>Make your events more discoverable, expand your reach effortlessly while being independent of other (commercial) platforms, and be a part of the growing decentralized web (the Fediverse). With the Event Bridge for ActivityPub Plugin for WordPress, your events can be automatically followed, aggregated and displayed across decentralized platforms like <a href="https://joinmastodon.org" rel="nofollow ugc">Mastodon</a> or <a href="https://gancio.org" rel="nofollow ugc">Gancio</a>, without any extra work. Forget the hassle of managing multiple social media accounts just to keep your audience informed.</p>
<p>This plugin is not an event managing plugin but an add-on to popular event plugins. It extends their functionality to fully support the <a href="https://wordpress.org/plugins/activitypub/" rel="ugc">ActivityPub plugin</a>. With the ActivityPub plugin people can follow your website directly and engage with your events just as they would on social media: liking, boosting and even commenting if you enable it. You retain full ownership of your content. By integrating into your existing setup, it ensures no extra work is needed while enhancing your events’ visibility across the web.</p>
<h4>Supported Event Plugins</h4>
<p>Full support (including importing events from the Fediverse):</p>
<ul>
<li><a href="https://de.wordpress.org/plugins/the-events-calendar/" rel="nofollow ugc">The Events Calendar</a></li>
<li><a href="https://de.wordpress.org/plugins/very-simple-event-list/" rel="nofollow ugc">VS Event List</a></li>
<li><a href="https://gatherpress.org/" rel="nofollow ugc">GatherPress</a></li>
</ul>
<p>Basic support (outgoing events):</p>
<ul>
<li><a href="https://de.wordpress.org/plugins/events-manager/" rel="nofollow ugc">Events Manager</a></li>
<li><a href="https://de.wordpress.org/plugins/wp-event-manager/" rel="nofollow ugc">WP Event Manager</a></li>
<li><a href="https://de.wordpress.org/plugins/wp-event-solution/" rel="nofollow ugc">Eventin</a></li>
<li><a href="https://webnus.net/modern-events-calendar/" rel="nofollow ugc">Modern Events Calendar Lite</a></li>

<li><a href="https://wordpress.org/plugins/eventprime-event-calendar-management/" rel="ugc">EventPrime – Events Calendar, Bookings and Tickets</a></li>
<li><a href="https://wordpress.org/plugins/eventon-lite/" rel="ugc">EventON – Events Calendar</a></li>
</ul>
<h4>How It Works</h4>
<p>With the Event Bridge for ActivityPub WordPress plugin, sharing your events is effortless and automatic! Once you create an event on your WordPress site, it is seamlessly shared across the decentralized web using the ActivityPub protocol.</p>
<div class="embed-vimeo" style="text-align: center;"><iframe loading="lazy" src="https://player.vimeo.com/video/1043105544" width="750" height="422" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe></div>
<p>Your events can be automatically delivered to platforms that fully support events, such as <a href="https://joinmobilizon.org/" rel="nofollow ugc">Mobilizon</a>, <a href="https://gancio.org" rel="nofollow ugc">Gancio</a>, <a href="https://friendi.ca" rel="nofollow ugc">Friendica</a>, <a href="https://hubzilla.org" rel="nofollow ugc">Hubzilla</a>, and <a href="https://pleroma.social/" rel="nofollow ugc">Pleroma</a>. These platforms create public event calendars by pulling in events from various sources, including your website. Any updates you make to your events are synced across these platforms—so you only need to manage your events on your own site, with no extra work required.</p>
<div class="embed-vimeo" style="text-align: center;"><iframe loading="lazy" src="https://player.vimeo.com/video/1043104445" width="750" height="422" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe></div>
<p>Even platforms that don’t yet fully support events, like <a href="https://joinmastodon.org" rel="nofollow ugc">Mastodon</a>, will still receive a detailed, well-composed summary of your event. The Event Federation plugin ensures that users from those platforms are provided with all important information about an event.</p>
<h4>Features for Your WordPress Events and the Fediverse</h4>
<p><strong>ActivityPub-Enabled Event Sharing:</strong> Your WordPress events are now compatible with the Fediverse, using the ActivityStreams format. This means your events can be easily discovered and followed by users on platforms like Mastodon and other ActivityPub-compatible services.</p>
<p><strong>Automatic Event Summaries:</strong> When your event is shared on the Fediverse, platforms like Mastodon that don’t fully support events will display a brief HTML summary of key details — such as the event’s title, start time, and location. This ensures that even if someone can’t view the full event on their platform, they still get the important info at a glance, with a link to your WordPress event page. Advanced users can create custom summaries via a set of shortcodes.</p>
<p><strong>Improved Event Discoverability:</strong> Your custom event categories are mapped to a set of default categories used in the Fediverse, helping your events reach a wider audience. This improves the chances that users searching for similar events on other platforms will find yours.</p>
<p><strong>Event Reminders for Your Followers:</strong> Often, events are planned well in advance. To keep your followers informed right in time, you can set up reminders that are supposed to trigger the events showing up in their timelines right before the event starts.</p>
<p><strong>External Event Sources:</strong>  This functionality is only available for a subset of the supported event plugins. It enables your WordPress site to act as a hub for displaying events from other ActivityPub profiles, aggregating them into a cohesive calendar view.</p>

<p>Enter the fediverse with <strong>ActivityPub</strong>, broadcasting your blog to a wider audience! Attract followers, deliver updates, and receive comments from a diverse user base of <strong>ActivityPub</strong>-compliant platforms.</p>
<p><span class="embed-youtube" style="text-align:center; display: block;"><iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/QzYozbNneVc?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe></span></p>
<p>With the ActivityPub plugin installed, your WordPress blog itself functions as a federated profile, along with profiles for each author. For instance, if your website is <code>example.com</code>, then the blog-wide profile can be found at <code>@example.com@example.com</code>, and authors like Jane and Bob would have their individual profiles at <code>@jane@example.com</code> and <code>@bob@example.com</code>, respectively.</p>
<p>An example: I give you my Mastodon profile name: <code>@pfefferle@mastodon.social</code>. You search, see my profile, and hit follow. Now, any post I make appears in your Home feed. Similarly, with the ActivityPub plugin, you can find and follow Jane’s profile at <code>@jane@example.com</code>.</p>
<p>Once you follow Jane’s <code>@jane@example.com</code> profile, any blog post she crafts on <code>example.com</code> will land in your Home feed. Simultaneously, by following the blog-wide profile <code>@example.com@example.com</code>, you’ll receive updates from all authors.</p>
<p><strong>Note</strong>: If no one follows your author or blog instance, your posts remain unseen. The simplest method to verify the plugin’s operation is by following your profile. If you possess a Mastodon profile, initiate by following your new one.</p>
<p>The plugin works with the following tested federated platforms, but there may be more that it works with as well:</p>
<ul>
<li><a href="https://joinmastodon.org/" rel="nofollow ugc">Mastodon</a></li>
<li><a href="https://pleroma.social/" rel="nofollow ugc">Pleroma</a>/<a href="https://akkoma.social/" rel="nofollow ugc">Akkoma</a></li>
<li><a href="https://friendi.ca/" rel="nofollow ugc">friendica</a></li>
<li><a href="https://hubzilla.org/" rel="nofollow ugc">Hubzilla</a></li>
<li><a href="https://pixelfed.org/" rel="nofollow ugc">Pixelfed</a></li>
<li><a href="https://socialhome.network/" rel="nofollow ugc">Socialhome</a></li>
<li><a href="https://join.misskey.page/" rel="nofollow ugc">Misskey</a></li>
</ul>
<p>Some things to note:</p>
<ol>
<li>The blog-wide profile is only compatible with sites with rewrite rules enabled. If your site does not have rewrite rules enabled, the author-specific profiles may still work.</li>
<li>Many single-author blogs have chosen to turn off or redirect their author profile pages, usually via an SEO plugin like Yoast or Rank Math. This is usually done to avoid duplicate content with your blog’s home page. If your author page has been deactivated in this way, then ActivityPub author profiles won’t work for you. Instead, you can turn your author profile page back on, and then use the option in your SEO plugin to noindex the author page. This will still resolve duplicate content issues with search engines and will enable ActivityPub author profiles to work.</li>
<li>Once ActivityPub is installed, <em>only new posts going forward</em> will be available in the fediverse. Likewise, even if you’ve been using ActivityPub for a while, anyone who follows your site will only see new posts you publish from that moment on. They will never see previously-published posts in their Home feed. This process is very similar to subscribing to a newsletter. If you subscribe to a newsletter, you will only receive future emails, but not the old archived ones. With ActivityPub, if someone follows your site, they will only receive new blog posts you publish from then on.</li>
</ol>
<p>So what’s the process?</p>
<ol>
<li>Install the ActivityPub plugin.</li>
<li>Go to the plugin’s settings page and adjust the settings to your liking. Click the Save button when ready.</li>
<li>Make sure your blog’s author profile page is active if you are using author profiles.</li>
<li>Go to Mastodon or any other federated platform, and search for your profile, and follow it. Your new profile will be in the form of either <code>@your_username@example.com</code> or <code>@example.com@example.com</code>, so that is what you’ll search for.</li>
<li>On your blog, publish a new post.</li>
<li>From Mastodon, check to see if the new post appears in your Home feed.</li>
</ol>
<p><strong>Note</strong>: It may take up to 15 minutes or so for the new post to show up in your federated feed. This is because the messages are sent to the federated platforms using a delayed cron. This avoids breaking the publishing process for those cases where users might have lots of followers. So please don’t assume that just because you didn’t see it show up right away that something is broken. Give it some time. In most cases, it will show up within a few minutes, and you’ll know everything is working as expected.</p>


ActivityPub

A lovely way to properly follow blog users from mastodon

Great way to start WordPress joining the Fediverse


With this plugin your posts appear automatically on Mastodon.



Replies on Mastodon becomes comments on your post.



Really, it couldn't be easier.


Brilliant


The indieweb and fediverse communities are doing great work and need to be acknowledged



this plugin works well and the devs are constantly improving it


Great concept and responsive devs


Love this plugin. Recent updates with threaded comments and now federated replies are just excellent - keeping the plugin moving in exactly the right direction. It's reinvigorated my interest in blogging! Hoping that some kind of support for displaying likes and boosts will come in the future, but otherwise it's getting to feel very complete.


Great plugin getting even better


The plugin works as described, providing a full ActivityPub integration from the moment you activate it.



There are a lot of options, some of which require a bit of extra research to understand (I recommend watching the Fediverse Files series on YouTube), but the defaults are solid and in most situations you won't want to change them.


Incredibly Powerful, a bit Complex, Solid Defaults


Great plugin, which evolves quickly and gets even better with every release!


Future of the Web


Not just an auto-poster - it it turns your WordPress blog into its own instance like a Mastodon server, so people can follow and reply to your blog directly from their Mastodon/GoToSocial/whatever account.



Images are attached to the Fediverse view, and remote replies show up locally as comments. People can boost your post directly instead of just linking to it. And they're still adding more capabilities with each release.



Note that a lot of the settings aren't in the plugin config page, they're put in the relevant categories. Followers show up on your user profile. You ban an instance by putting it in the general comments blocklist.



Works well with ClassicPress too.


(Almost) seamlessly connects your blog to the Fediverse.


Great plugin with regular updates. Does what it says on the label, and does it well. It makes my WP posts look great in the fediverse and boost, replies, and likes quickly make their way back to my site. 


Makes my WP posts look great in the fediverse

Great project

Connect your site to the Open Social Web and let millions of users follow, share, and interact with your content from Mastodon, Pixelfed, and more.
