November 2, 2025 — ‘It works on my machine’, ‘We can’t test that in staging’, ‘It seems to have been broken for a while’… This sounds familiar to many of us, and this is what I want to fix with this talk! I will share practical & easy ways to approach observability in WordPress, and move beyond logs to investigate and fix issues on websites, plugins & themes. I’ll demonstrate how modern observability turns reactive firefighting into proactive problem-solving, drawing from our experience maintaining some of WordPress’s most popular plugins.

June 7, 2025 — It works on my machine’, ‘We can’t test that in staging’, ‘It seems to have been broken for a while’… This sounds familiar to many of us, and this is what I want to fix with this talk! I will share practical ways to approach observability in WordPress, and move beyond logs to investigate and fix issues on websites, plugins & themes. I’ll demonstrate how modern observability turns reactive firefighting into proactive problem-solving, drawing from our experience maintaining some of WordPress’s most popular plugins. The audience will discover:

– How to implement error monitoring platforms like Sentry to catch issues before users do (thanks to an open-source & free WordPress plugin!)
– Using Metabase for data-driven insights to proactively observe and understand issues (open-source & free!)
– Visual regression testing with BackstopJS to prevent UI breaks (open-source and free!)
– Real-world examples of how these tools helped our teams manage daily deployments effectively

Whether you’re a plugin/theme developer or managing WordPress sites at scale, you’ll learn practical approaches to spend more time building features instead of fixing bugs. Audiences from website/business owners (even not technical), to developers & agencies can join!
