I write about building themes, Astro, and what makes websites fast. Everything here was learned building my own themes and websites.
Hans Martens, Astro theme developer in Veghel: building websites since 2010, from WordPress to Astro, the open-source Astro Rocket theme, and computers since 1992.
What it takes to build an Astro theme, from someone who shipped one: the discipline, the architecture, the documentation, the official directory, and maintaining it in the open.
Why Claude Code — running on Fable 5 — has become the coding partner I reach for on every Astro build. What it is, how I actually use it, and where it earns its keep.
Core Web Vitals explained in 2026 — what LCP, INP, and CLS measure, the thresholds Google uses, and how I improve Core Web Vitals on every Astro build.
A plain-language guide to Google's Lighthouse report: what the four scores measure, how to test any website in thirty seconds, and why the sites I build score 100 across the board.
Why Astro is the only web framework I reach for. What it is, how it works, and why everything I build — my website, my themes — is built on it.
