Tune in this Wednesday to learn more about the latest WordPress Core Performance Team efforts, including the View Transitions plugin!

Looking back at 10 years of contributions to WordPress Core, I feel extremely grateful, but I also feel proud. It made me think about how much giving back to open source can give back to you. I put together some related thoughts and personal stories: felix-arntz.me/blog/open-sour…

I am so excited to share our roadmap and approach for AI + the @WordPress Project. Earlier today, the team published a series of articles detailing what we’re building, why, and how you can get involved. make.wordpress.org/ai/2025/07/17/…

View Transitions 1.1.0 is out! Adding view transitions for WP Admin (opt-in), control over the transition duration, better interoperability with theme support, and compatibility with reduced motion preferences for accessibility. Give it a try: wordpress.org/plugins/view-t…

10 years ago today, I got my first props for contributing to WordPress Core. I've been contributing ever since, and it changed my life in so many ways. Here's 10 valuable lessons learned, which will hopefully help other current and future contributors: felix-arntz.me/blog/10-lesson…

Things you do as a web developer: Tell your landlord that the garage keypad is not working and you can't _toggle_ the door. 🤣

In 24 hours, @jameswlepage, @jeffpaul, @swissspidy and myself will be discussing AI and WordPress in a panel as part of the #TheAgencyAdvantage virtual conference. Happening on June 24 at 12pm ET. Join us: cloudways.com/en/agency-adva…

I like this take by @KentBeck on how AI-assisted programming changes the balance of which skills are most important

The WordPress AI Team is building a PHP AI Client SDK and needs your input. Let's say there was a method `textResult(p)`, which returns a complex LLM result object for a text generation request. If you only want the candidate text as string, what API is more intuitive to you?

We used to build websites. Now we build pipelines, frameworks, and hydration strategies - just to publish text. This isn’t progress. It’s complexity, by design. We need to escape the JavaScript framework trap. jonoalderson.com/conjecture/jav…

I recently migrated the ~80 file JavaScript codebase of the AI Services WordPress plugin to TypeScript - a perfect use-case for AI assistance, for such a beneficial yet tedious task. Read more about how using Cline and Gemini sped things up substantially: felix-arntz.me/blog/migrating…

Coming soon in the View Transitions plugin for WordPress: View transitions for WP Admin! This idea started at the #WCEU Contributor Day, and @mukeshpanchal27 has been bringing it to fruition. 🎉 Making WP Admin feel like an SPA without it suffering the complexity of being one.

Just a casual Swarm check in at my neighborhood cafe. 😂🤯

New profile picture (about time)! Thanks to @NiloVelez for capturing me at #WCEU!

Curious on how to build a WooCommerce AI Bundle Generator with React & AI Services? Of course you are, and @briancoords has got your back in this video tutorial youtube.com/watch?v=wqVD-W…
