Overview
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 functions as a federated profile, along with profiles for each author.

Makes my WP posts look great in the fediverse
by Chuck Grimmett·2 months ago
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.
Thank You for Making Fediverse Connections Possible

As someone working on the Korean translation of this plugin, I have seen first-hand how important it is for WordPress users to connect with the Fediverse. This plugin provides a bridge that makes such integration possible. Thanks to the developers, Korean users can now more easily explore and join the open social web. I deeply appreciate the effort, vision, and continuous improvements behind this project.
Worked out of the box. Brilliant.

I’ve installed and setup other ActivityPub servers usually some time & testing required along with tweaks.
However with the WP ActivityPub plug-in it, surprisingly, functioned properly <gasp!> right after install. What a joy. Thank you.
Excellent plugin, easily join the Fediverse in minutes!

Great plugin (actively maintained!), great support, a very nice way to join the Fediverse and automatically share posts and any kind of CPT to the Fediverse audience.
I was initially sharing posts using my personal Mastodon account, but it’s much nicer to have your dedicated account for your blogs (and/or authors).
Thanks for this plugin!
Best thing since WordPress
