Every Wumty developer tool is designed to work seamlessly with your Astro + SolidJS templates. These are not generic plugins — they’re purpose-built systems that integrate with content collections, theme tokens, and the monorepo architecture.
The Performance Toolkit handles image optimization with sharp, font loading with display:swap and preconnect hints, per-component CSS scoping, and bundle analysis. It’s the system behind every Wumty template’s 100/100 Lighthouse scores.
The SEO Toolkit generates Schema.org structured data, Open Graph tags, XML sitemaps, and canonical URLs automatically from your content collections and config files. Define your business info once — the toolkit generates valid JSON-LD for every page type.
The Theme System controls your entire site’s visual identity from theme.json. Define light and dark color palettes, typography, and spacing as JSON tokens. Every shared component reads tokens via CSS custom properties. Dark mode switching works with zero flash of unstyled content, even with Astro view transitions.
All tools are included with Pro and Agency kits. The SEO Toolkit and Theme System are also available with the free Starter Kit.
