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.

With the ActivityPub plugin installed, your WordPress blog itself function as a federated profile, along with profiles for each author. For instance, if your website is, then the blog-wide profile can be found at, and authors like Jane and Bob would have their individual profiles at and, respectively.

An example: I give you my Mastodon profile name: 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

Once you follow Jane’s profile, any blog post she crafts on will land in your Home feed. Simultaneously, by following the blog-wide profile, 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:

Some things to note:

  1. 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.
  2. 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.
  3. 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.

So what’s the process?

  1. Install the ActivityPub plugin.
  2. Go to the plugin’s settings page and adjust the settings to your liking. Click the Save button when ready.
  3. Make sure your blog’s author profile page is active if you are using author profiles.
  4. 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 or, so that is what you’ll search for.
  5. On your blog, publish a new post.
  6. From Mastodon, check to see if the new post appears in your Home feed.

Please note that 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.

Què és «ActivityPub for WordPress»

ActivityPub for WordPress amplia el WordPress amb algunes característiques del Fedivers, però no competeix amb plataformes com Friendica o Mastodon. Si voleu executar una xarxa social descentralitzada, utilitzeu Mastodon o GNU social.

Què passa si esteu executant el vostre blog en un subdirectori?

Perquè WebFinger funcioni, s’ha d’assignar al directori arrel de l’URL on resideix el vostre blog.


Afegiu el següent al fitxer .htaccess al directori arrel:

RedirectMatch "^\/\.well-known/(webfinger|nodeinfo|x-nodeinfo2)(.*)$" /blog/.well-known/$1$2

On «blog» és el camí al subdirectori on resideix el vostre blog.


Afegiu el següent a site.conf a sites-available:

location ~* /.well-known {
    allow all;
    try_files $uri $uri/ /blog/?$args;

On «blog» és el camí al subdirectori on resideix el vostre blog.

What if you are running your blog in a subdirectory, but have a different [wp_siteurl](

In that case you don’t need the redirect, because the index.php will take care of that.


The plugin uses PHP Constants to enable, disable or change its default behaviour. Please use them with caution and only if you know what you are doing.

  • ACTIVITYPUB_REST_NAMESPACE – Change the default Namespace of the REST endpoint. Default: activitypub/1.0.
  • ACTIVITYPUB_EXCERPT_LENGTH – Change the length of the Excerpt. Default: 400.
  • ACTIVITYPUB_SHOW_PLUGIN_RECOMMENDATIONS – show plugin recommendations in the ActivityPub settings. Default: true.
  • ACTIVITYPUB_MAX_IMAGE_ATTACHMENTS – Change the number of attachments, that should be federated. Default: 3.
  • ACTIVITYPUB_HASHTAGS_REGEXP – Change the default regex to detect hashtext in a text. Default: (?:(?<=\s)|(?<=<p>)|(?<=<br>)|^)#([A-Za-z0-9_]+)(?:(?=\s|[[:punct:]]|$)).
  • ACTIVITYPUB_USERNAME_REGEXP – Change the default regex to detect @-replies in a text. Default: (?:([A-Za-z0-9\._-]+)@((?:[A-Za-z0-9_-]+\.)+[A-Za-z]+)).
  • ACTIVITYPUB_CUSTOM_POST_CONTENT – Change the default template for Activities. Default: <strong>[ap_title]</strong>\n\n[ap_content]\n\n[ap_hashtags]\n\n[ap_shortlink].
  • ACTIVITYPUB_DISABLE_REWRITES – Disable auto generation of mod_rewrite rules. Default: false.
  • ACTIVITYPUB_DISABLE_INCOMING_INTERACTIONS – Block incoming replies/comments/likes. Default: false.
  • ACTIVITYPUB_DISABLE_OUTGOING_INTERACTIONS – Disable outgoing replies/comments/likes. Default: false.
  • ACTIVITYPUB_SHARED_INBOX_FEATURE – Enable the shared inbox. Default: false.
  • ACTIVITYPUB_SEND_VARY_HEADER – Enable to send the Vary: Accept header. Default: false.

Where can you manage your followers?

If you have activated the blog user, you will find the list of his followers in the settings under /wp-admin/options-general.php?page=activitypub&tab=followers.

The followers of a user can be found in the menu under “Users” -> “Followers” or under wp-admin/users.php?page=activitypub-followers-list.

For reasons of data protection, it is not possible to see the followers of other users.

The next great social network is just the Web. This plugin is the most important feature in WordPress. It enables over 40% of the entire Web to directly own their social profiles, relationships with their audiences, and distribution. I look forward to the continued iteration of this plugin. Each release brings new features that lessen the need for creators to have a separate Mastodon account.

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.

Version 2.0 takes this plugin from "good" to "amazing," with full reply federation, which means: 1: You post.2: Someone sees your post on, say, Mastodon, and replies to it, and that reply shows up in your comments on Wordpress.3: You reply to their comment from wordpress...4: ...and they see it back on Mastodon, in their timeline, like any other Mastodon reply. You can even tag Federation people into discussions in replies, the same way you'd tag in anyone else. (By mentioning them with their full account - @ user @ instance - like you would normally.) Depending upon what you want out of federated social media, this means Wordpress could be your only Federation portal... and you'd be fine.This is a big deal.
