Built for developers shipping APIs, dashboards, and dev tools. Four WCAG AA themes, 57 typed components, cosmic backgrounds, and perfect Lighthouse scores. Free forever, MIT licensed.
Built with the best of the modern web
No shopping for components, no waiting for accessibility audits. Galaxis ships the whole stack — themed, typed, and tested.
100/100/100/100 on every page. Self-hosted fonts with metric-adjusted fallbacks, optimized images, zero runtime JS on static routes.
Four curated purple-family themes. Every brand-on-background pairing verified by the contrast audit script.
Zod-validated collections for blog, projects, authors, FAQs.
Opt-in internationalization with locale-prefixed routes, hreflang tags, and a typed t() helper. Turn it on with one flag — off by default so single-locale sites pay nothing for it.
Aurora, Starfield, DotGrid, OrbitRings — pure CSS, reduced-motion safe, themed by your active brand colour.
JSON-LD, sitemap, robots, OG images, RSS — all wired.
One git clone, one site.config.ts, and your dev-tool marketing site is live. No design tools needed — the logo, favicon, and brand colours generate from one file. No license keys. No paid tiers.
Performance, accessibility, best practices, and SEO — every score perfect on mobile and desktop. What does this score mean?
Placeholder quotes — replace with testimonials from devs who shipped on Galaxis.
"We shipped our API status page in a weekend. The bento grid and the cosmic backgrounds did all the visual heavy lifting — we just swapped the copy and deployed."

Indie dev, ping-mate
"Best free Astro theme I've used for a dev-tool launch. The WCAG AA audit script alone saved us a week of contrast tuning — and we didn't have to argue about license terms."

CTO, Stackform
