I build lightning-fast Astro 7 themes — like Astro Rocket, my starter theme to build anything on. Based in Veghel, the Netherlands.
MIT licensed, made for the Astro community.
Interfaces that feel obvious. Every component designed to look right in every colour theme, in light and dark mode, on every screen.
Astro, Tailwind, and a clean architecture: lightning-fast on day one, easy to maintain on day 500, with SEO and accessibility built in.
New features ship opt-in, so existing sites keep working. Everything is documented, and every GitHub issue gets a real conversation.
My beautiful and fast theme to build your next website with.
95 stars and 47 forks from developers around the world, built in the open.
Listed in the official Astro themes directory, used by developers worldwide.
It powers the website you're looking at right now: every page, every component.

The free, open-source Astro theme I built — a complete starter with a living colour system, born from my own website and listed on Astro's official directory.
The developer website I designed and built — hansmartens.dev — and the project my open-source Astro Rocket theme grew out of.
Web design and development are my craft — and my favourite way to spend a day. I build with Astro because it matches how I think about the web: lean, purposeful, and built to last. Every detail matters to me: a site should look great, load fast, and get found by Google and AI assistants.
On the blog, I write about building themes, Astro, and what makes websites fast.

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.
