Capri lets you build static sites with interactive islands. There are no new APIs or patterns to learn.
It was created in search of the most carbon-friendly way to build a medium-sized website with mostly static content.
This is free and open source software.
Key Features
- Components-based – Capri sites are built with components. Use a framework like React, Preact, Svelte, Vue or SolidJS rather than a templating language.
- A Capri site does not contain any Capri-specific code at all. If you remove the Capri plugin from your Vite config, you end up with a fully functional application, albeit no longer static.
- Use the ecosystem of your favourite framework directly, without any detours.
- Ships zero KB of JavaScript to the browser by default.
- Live CMS previews.
- If parts of your site need to be interactive, you turn them into islands by simply naming your components
*.island.(tsx|vue|svelte).
