Event Bridge for ActivityPub

Make your events more discoverable, expand your reach effortlessly while being independent of other (commercial) platforms, and be a part of the growing decentralized web (the Fediverse). With the Event Bridge for ActivityPub Plugin for WordPress, your events can be automatically followed, aggregated and displayed across decentralized platforms like Mastodon or Gancio, without any extra work. Forget the hassle of managing multiple social media accounts just to keep your audience informed.

This plugin is not an event managing plugin but an add-on to popular event plugins. It extends their functionality to fully support the ActivityPub plugin. With the ActivityPub plugin people can follow your website directly and engage with your events just as they would on social media: liking, boosting and even commenting if you enable it. You retain full ownership of your content. By integrating into your existing setup, it ensures no extra work is needed while enhancing your events’ visibility across the web.

How It Works

With the Event Bridge for ActivityPub WordPress plugin, sharing your events is effortless and automatic! Once you create an event on your WordPress site, it is seamlessly shared across the decentralized web using the ActivityPub protocol.

Your events can be automatically delivered to platforms that fully support events, such as Mobilizon, Gancio, Friendica, Hubzilla, and Pleroma. These platforms create public event calendars by pulling in events from various sources, including your website. Any updates you make to your events are synced across these platforms—so you only need to manage your events on your own site, with no extra work required.

Even platforms that don’t yet fully support events, like Mastodon, will still receive a detailed, well-composed summary of your event. The Event Federation plugin ensures that users from those platforms are provided with all important information about an event.

Features for Your WordPress Events and the Fediverse

ActivityPub-Enabled Event Sharing: Your WordPress events are now compatible with the Fediverse, using the ActivityStreams format. This means your events can be easily discovered and followed by users on platforms like Mastodon and other ActivityPub-compatible services.

Automatic Event Summaries: When your event is shared on the Fediverse, platforms like Mastodon that don’t fully support events will display a brief HTML summary of key details — such as the event’s title, start time, and location. This ensures that even if someone can’t view the full event on their platform, they still get the important info at a glance, with a link to your WordPress event page. Advanced users can create custom summaries via a set of shortcodes.

Improved Event Discoverability: Your custom event categories are mapped to a set of default categories used in the Fediverse, helping your events reach a wider audience. This improves the chances that users searching for similar events on other platforms will find yours.

Event Reminders for Your Followers: Often, events are planned well in advance. To keep your followers informed right in time, you can set up reminders that are supposed to trigger the events showing up in their timelines right before the event starts.

External Event Sources: This functionality is only available for a subset of the supported event plugins. It enables your WordPress site to act as a hub for displaying events from other ActivityPub profiles, aggregating them into a cohesive calendar view.
