Title: My FOSDEM 2024 Talk: Migrating the WordPress Community from Slack to Matrix Author: Alex Kirk Published: February 16, 2024 --- # My FOSDEM 2024 Talk: Migrating the WordPress Community from Slack to Matrix February 16, 2024 When I submitted my application for a talk at [FOSDEM 2024](https://fosdem.org/2024/), we were still on for [migrating the WordPress community to Matrix](https://make.wordpress.org/project/2023/11/30/embracing-matrix-for-enhanced-communication/). Alas, there were many factors that led us to [pause the transition](https://make.wordpress.org/project/2023/12/12/update-on-matrix-migration-pausing-the-transition/) indefinitely, [announced by Matt at the Q&A of State of the Word 2023](https://youtu.be/S01uBD2pyQY?feature=shared&t=665). The most important factors were [accessibility problems](https://github.com/Automattic/matrix-react-sdk/pulls), some important feature-imparity compared with Slack, and the [license changes at Element](https://element.io/blog/element-to-adopt-agplv3/)( to AGPL, with the requirement to sign a CLA when contributing). The WordPress community has [collected their issues in a Github repository](https://github.com/WordPress/Matrix/issues). We tried hard to overcome the issues, through [documentation](https://make.wordpress.org/chat/matrix/), education (some things just work differently in a federated environment), and upstream patches (for example to [address some of the accessibility problems](https://github.com/matrix-org/matrix-react-sdk/pulls/akirk)). In the end, I did not cancel but [held my talk on February 4 at FOSDEM 2024 in Brussels](https://fosdem.org/2024/schedule/event/fosdem-2024-2824-embracing-matrix-for-enhanced-communication-migrating-the-wordpress-community-from-slack-to-matrix/), explaining all the things we did to lower the barrier of entry: * Allow authenticating with WordPress using SSO via OpenID Connect, by creating the [WP OpenID Connect Server plugin](https://wordpress.org/plugins/openid-connect-server/). * Directly embed a Matrix chat in a WordPress page with a block, by creating the [Chatrix plugin](https://wordpress.org/plugins/chatrix/). As well as bots and integration we created to fulfill the specific needs, such as these Maubot plugins: * [Post to room](https://github.com/WordPress/matrix-bots/blob/main/plugins/post_to_room/): post messages via webhook * [Relay](https://github.com/WordPress/matrix-bots/blob/main/plugins/relay/): an integration can react to room messages via webhook * [Group mentions](https://github.com/wordpress/matrix-bots): upon command a bot mentions many people * [Watchdog](https://github.com/WordPress/matrix-bots/blob/main/plugins/watchdog/): alert about community created rooms Also, we held [weekly meetings in the WordPress meta chat](https://make.wordpress.org/meta/chat/) throughout the year, and [published meeting notes](https://make.wordpress.org/meta/tag/matrix/) afterwards. There is a lot more in my presentation, I hope that [my presentation slides](https://alex.kirk.at/fosdem2024/) can be helpful to other communities (or companies) trying to migrate from Slack to Matrix. Maybe some things that were a blocker for the WordPress community are not so important for other communities. Finally, here is the [video of the ~30 minutes presentation](https://fosdem.org/2024/schedule/event/fosdem-2024-2824-embracing-matrix-for-enhanced-communication-migrating-the-wordpress-community-from-slack-to-matrix/): [https://video.fosdem.org/2024/h1309/fosdem-2024-2824-embracing-matrix-for-enhanced-communication-migrating-the-wordpress-community-from-slack-to-matrix.av1.webm](https://video.fosdem.org/2024/h1309/fosdem-2024-2824-embracing-matrix-for-enhanced-communication-migrating-the-wordpress-community-from-slack-to-matrix.av1.webm) [FOSDEM 2024 talk by Alex Kirk: Embracing Matrix for Enhanced Communication: Migrating the WordPress Community from Slack to Matrix](https://fosdem.org/2024/schedule/event/fosdem-2024-2824-embracing-matrix-for-enhanced-communication-migrating-the-wordpress-community-from-slack-to-matrix/) Kudos to my colleagues [Paulo Pinto](https://profiles.wordpress.org/psrpinto/) and [Ashish Kumar](https://profiles.wordpress.org/ashfame/) who did a lot of the heavy lifting in the effort.

[@alex](https://alex.kirk.at/author/alex/) Thank you for giving you talk "again" at FOSDEM, Alex! I was surprised to see it on the schedule again after already heading you talk under the same title at matrix community summit 2023, when instead you gave a follow-up talk that was extremely insightful as to why a migration might fail and bringing a LOT of these little issues to light. Thank you also for all these small bot snippets etc that look very interesting for use in other communities too! 5. a. ![Alex Kirk Avatar](https://alex.kirk.at/wp-content/uploads/sites/2/2025/06/cropped- 2025.Alex-512x512-1-48x48.jpg) b.

My thinking was that there would be enough people in the room who hadn’t seen the community summit talk so that it would still be new to them, along with the intro-part of the talk (which was very similar to the summit indeed). So, to make it worthwhile for everyone, I made it a follow-up talk given the events that had taken place since the first one. I’m glad you found it useful! e.
