WordPress.com owner Automattic acquires an ActivityPub plugin so blogs can join the Fediverse

WordPress.com sites now have an easier way to integrate with the Fediverse, including Mastodon. Automattic, the company behind WordPress.com, Tumblr, and other web publishing tools is the new owner of the ActivityPub for WordPress plugin and has also recruited its developer to come work for the company, according to Automattic CEO Matt Mullenweg.

The newly acquired plugin allows WordPress.org and WordPress.com blog owners to reach readers on federated platforms, like the Twitter rival Mastodon and others. Once installed, readers are able to follow the WordPress blogs on their preferred federated platform, view the blog posts, and reply with comments. The replies posted to a federated site like Mastodon then become blog post comments.

The developer has been working to improve the plugin’s WordPress integration and add support for threaded comments, among other things, the plugin’s webpage notes.

At present, the ActivityPub plugin supports federated platforms including Mastodon, Pleroma, Friendica, HubZilla, Pixelfed, SocialHome, and Misskey. It’s been downloaded over 35,000 times to date, according to its statistics page.

By going in-house with Automattic, the developer, Matthias Pfefferle, will have access to further resources and support to make the plugin more functional over time. Mullenweg says the plan now is to test and experiment with the plugin — much as the company previously did with the Gutenberg editor — which is the first step to any major changes to the platform.

Mullenweg has been bullish on the promises of the Fediverse — the decentralized web powered by interconnected servers running open source applications, including the newly popular Mastodon, the Instagram-like Pixelfed, and others. Late last year, for example, the CEO said Tumblr would add support for ActivityPub, the protocol that powers Mastodon and other decentralized social apps. However, he had not declared any specific plans for WordPress.com.

ActivityPub is not the only protocol Automattic is testing, Mullenweg says. The company has been digging into a variety of protocols and has been testing Nostr, and Bluesky along with ActivityPub.

“I’m still curious about Nostr and other protocols,” Mullenweg told TechCrunch. “It’s all very nascent right now.”

Terms of the plugin’s acquisition aren’t being disclosed, but this was not a large purchase as the plugin is a small, one-person operation.

Mullenweg also notes his company has not been directly impacted by the SVB crisis but had reached out to various companies and partners with offers to help.
