Pulsar is a fast, modern blog theme built with Tailwind CSS, ready to use out of the box and easy to personalize through a single config file.
It ships minimal JavaScript and pre-renders all pages as static HTML. Your blog posts are type-safe and validated at build time through Astro Content Collections.
Images are automatically served as WebP with fallbacks for older browsers.
Dark mode works without a flash of unstyled content and persists across sessions. SEO is handled comprehensively: meta tags, Open Graph, Twitter Cards, JSON-LD structured data, automatic sitemap generation, and canonical URLs. Syntax highlighting uses Prism with the GitHub Dark theme. Google Analytics 4 and social links for GitHub, Twitter, LinkedIn, and YouTube are supported out of the box.
Named after pulsars, the rotating neutron stars that emit powerful beams of radiation, because it's fast, reliable, and a little dramatic.
