ActivityPub

This is BETA software, see the FAQ to see the current feature set or rather what is still planned.

The plugin implements the ActivityPub protocol for your blog. Your readers will be able to follow your blogposts on Mastodon and other federated platforms that support ActivityPub.

The plugin works with the following federated platforms:

Follow the normal instructions for installing WordPress plugins.

Automatic Plugin Installation

To add a WordPress Plugin using the built-in plugin installer:

Go to Plugins > Add New.
Type “activitypub” into the Search Plugins box.
Find the WordPress Plugin you wish to install.
1. Click Details for more information about the Plugin and instructions you may wish to print or save to help setup the Plugin.
2. Click Install Now to install the WordPress Plugin.
The resulting installation screen will list the installation as successful or note any problems during the install.
If successful, click Activate Plugin to activate it, or Return to Plugin Installer for further actions.

Manual Plugin Installation

There are a few cases when manually installing a WordPress Plugin is appropriate.

If you wish to control the placement and the process of installing a WordPress Plugin.
If your server does not permit automatic installation of a WordPress Plugin.
If you want to try the latest development version.

Installation of a WordPress Plugin manually requires FTP familiarity and the awareness that you may put your site at risk if you install a WordPress Plugin incompatible with the current version or from an unreliable source.

Backup your site completely before proceeding.

To install a WordPress Plugin manually:

Download your WordPress Plugin to your desktop.
- Download from the WordPress directory
- Download from GitHub
If downloaded as a zip archive, extract the Plugin folder to your desktop.
With your FTP program, upload the Plugin folder to the wp-content/plugins folder in your WordPress directory online.
Go to Plugins screen and find the newly uploaded Plugin in the list.
Click Activate to activate it.

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 are the differences between this plugin and Pterotype?

Compatibility

ActivityPub for WordPress is compatible with OStatus and IndieWeb plugin suites. Pterotype is incompatible with the standalone WebFinger plugin, so it can’t be run together with OStatus.

Custom tables

Pterotype creates/uses a bunch of custom tables, ActivityPub for WordPress only uses the native tables and adds as little meta data as possible.

What if you are running your blog in a subdirectory?

In order for webfinger to work, it must be mapped to the root directory of the URL on which your blog resides.

Apache

Add the following to the .htaccess file in the root directory:

RedirectMatch "^\/\.well-known(.*)$" "\/blog\/\.well-known$1"

Where ‘blog’ is the path to the subdirectory at which your blog resides.

Nginx

Add the following to the site.conf in sites-available:

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

Where ‘blog’ is the path to the subdirectory at which your blog resides.

Just installed on my Robotics Team's blog and it works. Haven't played with it much yet. I hope this only gets better!

Works very well out of the box.

As a person who believes that federation achieved with ActivityPub or a similar protocol is the future, I think this plugin is a must if you are using WordPress to run a blog. Wish that every single WordPress site starts using this plugin.

My blog appeared promptly on the fediverse. That's a nice addition to allow people to follow me on their terms.

I've tested it with Mastodon and it allows people to follow my blog via ActivityPub. I do wish that when I reply to comments it would also notify people though.

Experimenting with the Fediverse (Mastodon et al), I found this plugin and it worked nicely. Waiting eagerly for new updates/festures... Keep the good work!
