Ultimate Astro is an open-source Astro starter template that showcases hybrid multi-framework development by combining React, Vue, Svelte, and SolidJS components in a single project. Built on the Astro platform with TypeScript and styled with Tailwind CSS, it provides a preconfigured project structure with separate component folders for each framework, a shared UI directory, layouts, data files, icons, and global styles.
What is Ultimate Astro?
Ultimate Astro is a starter template for the Astro static site generator that integrates four frontend frameworks — React, Vue, Svelte, and SolidJS — into one codebase. The template takes a fresh Astro project and adds framework-specific component directories, shared UI components, layouts, pages, data files, icons, and global styles, producing a development-ready site that demonstrates cross-framework coexistence. It is maintained by GitHub user Marve10s, listed on the Astro Themes directory, and deployed as a live demo on Vercel at ultimate-astro-template.vercel.app.
Key Features
- Multi-framework support — React, Vue, Svelte, and SolidJS components each have their own directory under
src/components/, so you can build and compare components in four frameworks within one project. - Astro partial hydration — Use
client:*directives to hydrate only the interactive islands, keeping the rest of the page as static HTML for fast load times. - Tailwind CSS styling — Global styles and custom utilities are configured via
tailwind.config.cjs, giving you control over color schemes, breakpoints, typography, and custom utilities. - Organized project structure — Separate folders for assets, components, data, icons, layouts, pages, and styles, plus a
ui/directory for shared cross-framework components. - High PageSpeed scores — The live demo reports 99/100 performance, 97/100 accessibility, 100/100 best practices, and 100/100 SEO on PageSpeed Insights.
- MIT-licensed open source — Free to use, modify, and redistribute under the MIT License.
- Community showcases — The README features modifications from contributors, including custom orb background colors and a DevContainer setup.
Who is it for?
- Astro developers who want to experiment with mixing multiple frameworks in one project without configuring each integration from scratch.
- Frontend framework explorers who want to compare React, Vue, Svelte, and SolidJS side-by-side in a real, buildable codebase.
- Starter template users looking for a preconfigured, high-performance base with Tailwind CSS and TypeScript for a landing page or personal site.
- Learners of Astro's islands architecture who need working examples of
client:*directives and multi-framework component integration.
What can you do with Ultimate Astro?
- Build a landing page — Use the existing pages and layouts to assemble a marketing or portfolio site, then customize content and styling.
- Test framework interoperability — Create components in any of the four frameworks and embed them in the same Astro page to see how they interact and share data.
- Customize design tokens — Edit
tailwind.config.cjsto change colors, breakpoints, and typography across the entire site. - Contribute a showcase — Fork the repository, make modifications, and share your result via a GitHub issue; the README encourages community showcases.
How does Ultimate Astro work?
