Why I Built This

After building the marketing site for Apatero and achieving perfect Lighthouse scores, I extracted the blog architecture into a reusable, open-source template. The goal was to give developers a starting point that is genuinely fast and SEO-optimized out of the box, not just "good enough."

Outcome

The template delivers sub-second page loads and perfect SEO scores, making it an ideal starting point for developer blogs, company blogs, and content-driven sites. Open-sourced for community use.
