FediBoost extends the ActivityPub plugin by automatically boosting your WordPress posts on your connected Mastodon accounts when they are published.
When you publish a new post on your WordPress site, FediBoost will automatically boost (reblog) that post on your linked Mastodon account, helping increase visibility across the fediverse.
Features:
<ul>
<li>Automatic boosting of new posts to connected Mastodon accounts</li>
<li>Seamless integration with the ActivityPub plugin</li>
<li>No additional configuration required after setup</li>
</ul>
Requirements:
<ul>
<li>The <a href="https://wordpress.org/plugins/activitypub/" rel="ugc">ActivityPub plugin</a> must be installed and configured</li>
<li>A connected Mastodon account via ActivityPub</li>
</ul>
<h3>Developer Hooks</h3>
FediBoost provides several filters that allow developers to customize its behavior. All filters follow WordPress coding standards and can be added to your theme’s functions.php file or a custom plugin.
<h4>fediboost_should_boost_post</h4>
Control whether a specific post should be boosted. Return false to skip boosting for the given post. Default: true.
Parameters:
<ul>
<li><code>$should_boost</code> (bool) — Whether the post should be boosted.</li>
<li><code>$post</code> (WP_Post) — The post object being published.</li>
</ul>
Example:
<pre><code>add_filter( 'fediboost_should_boost_post', function( $should_boost, $post ) {
 // Don't boost posts in the "internal" category.
 if ( has_category( 'internal', $post ) ) {
 return false;
 }
 return $should_boost;
}, 10, 2 );
</code></pre>
<h4>fediboost_boost_delay</h4>
Delay in seconds after ActivityPub federation completes before the boost is executed. This delay is only used when the federation completion hook fires successfully. Default: 30.
Parameters:
<ul>
<li><code>$delay</code> (int) — The delay in seconds.</li>
</ul>
Example:
<pre><code>add_filter( 'fediboost_boost_delay', function( $delay ) {
 // Wait 2 minutes after federation before boosting.
 return 120;
} );
</code></pre>
<h4>fediboost_fallback_delay</h4>
Delay in seconds before a boost is executed when the ActivityPub federation completion hook does not fire. This acts as a safety net for older versions of the ActivityPub plugin that do not support the <code>activitypub_outbox_processing_complete</code> hook. If the federation hook fires first, the fallback is cancelled and <code>fediboost_boost_delay</code> is used instead. Default: 300 (5 minutes).
Parameters:
<ul>
<li><code>$delay</code> (int) — The fallback delay in seconds.</li>
</ul>
Example:
<pre><code>add_filter( 'fediboost_fallback_delay', function( $delay ) {
 // Wait 10 minutes in the fallback path.
 return 600;
} );
</code></pre>
<h4>fediboost_manage_capability</h4>
WordPress capability required to manage FediBoost settings. Default: ‘manage_options’. Note: a floor of ‘edit_others_posts’ is enforced regardless of this filter’s return value, so you cannot lower the requirement below that capability.
Parameters:
<ul>
<li><code>$capability</code> (string) — The required capability.</li>
</ul>
Example:
<pre><code>add_filter( 'fediboost_manage_capability', function( $capability ) {
 // Allow editors to manage FediBoost settings.
 return 'edit_others_posts';
} );
</code></pre>
<h4>fediboost_max_accounts</h4>
Maximum number of connected Mastodon accounts. Default: 10.
Parameters:
<ul>
<li><code>$max</code> (int) — The maximum number of accounts.</li>
</ul>
Example:
<pre><code>add_filter( 'fediboost_max_accounts', function( $max ) {
 // Allow up to 25 connected accounts.
 return 25;
} );<h3>External Services</h3>
</code></pre>
FediBoost connects to external Mastodon instances that you configure (e.g., mastodon.social). This communication is essential for the plugin to function and is initiated only with the instance you explicitly provide.
During setup:
<ul>
<li>FediBoost registers an OAuth application on your Mastodon instance and performs an authorization flow so it can act on your behalf.</li>
</ul>
When a post is published:
<ul>
<li>FediBoost searches for the post on your Mastodon instance and performs a reblog (boost) via the Mastodon API.</li>
</ul>
Data sent to your Mastodon instance:
<ul>
<li>Your instance URL</li>
<li>OAuth authorization codes</li>
<li>Search queries to locate your posts</li>
<li>Reblog (boost) requests</li>
</ul>
Data stored locally on your WordPress site:
<ul>
<li>Encrypted OAuth tokens</li>
<li>Your Mastodon username</li>
<li>Your Mastodon instance URL</li>
</ul>
Each Mastodon instance has its own privacy policy and terms of service. You can find a list of instances and their policies at <a href="https://joinmastodon.org/servers" rel="nofollow ugc">joinmastodon.org/servers</a>.
This plugin does not send data to any third-party service other than the Mastodon instance(s) you explicitly configure.

FediBoost


This plugin solves a core frustration in the fediverse: Sites have their own identities, but most of us already have separate identities in the fediverse, too. FediBoost automatically boosts posts from your site’s identity from your own identity in the fediverse.



It does what it says on the label, and it even works with custom post types if ActivityPub is enabled for them. It has wp-cli support, too.



If you federate your blog posts with the ActivityPub plugin and want to automatically boost them from your main account, give it a try!

Enter the fediverse with ActivityPub, broadcasting your blog to a wider audience! Attract followers, deliver updates, and receive comments from a diverse user base of ActivityPub-compliant platforms.
<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>
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.
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>.
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.
Note: 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.
The plugin works with the following tested federated platforms, but there may be more that it works with as well:
<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>
Some things to note:
<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, only new posts going forward 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>
So what’s the process?
<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>
Note: 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.

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

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.
