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:

Algunas cosas a tener en cuenta:

  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.

¿Cuál es el proceso?

  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.

Ten en cuenta que la nueva entrada puede tardar unos 15 minutos en aparecer en tu feed federado. Esto se debe a que los mensajes se envían a las plataformas federadas utilizando un cron con retraso. De este modo se evita interrumpir el proceso de publicación en los casos en que los usuarios tengan muchos seguidores. Así que, por favor, no asumas que porque no lo hayas visto aparecer inmediatamente es que algo está roto. Dale un poco de tiempo. En la mayoría de los casos, aparecerá en unos minutos, y sabrás que todo está funcionando como se esperaba.

What is «ActivityPub for WordPress»

ActivityPub for WordPress extends WordPress with some Fediverse features, but it does not compete with platforms like Friendica or Mastodon. If you want to run a decentralized social network, please use Mastodon or GNU social.

What if you are running your blog in a subdirectory?

If you are running your blog in a subdirectory, but have a different wp_siteurl, 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.

There isn’t rating scale that I would like to leave here – Max isn’t enough. A wise man’s words are worth their weight in gold. The plugin is designed for all platforms using the ActivityPub protocol, but maybe one day there will be a feature that will allow me to create a comment (toot) in Mastodon from a form on my blog page when WordPress local commenting system is disabled 🙂

Nice when it works, sadly most of the time it just doesn’t work.

I was an early(ish) adopter of the plugin when I first learned of it. I installed it on a couple of self-hosted sites that I wanted to officially federate, and now I am at the point where every site I have has Activitypub installed.
