Build with HTML again.

The HTML, CSS, and JavaScript you know, with components, routing, and server rendering powered by the next generation of HTML.

Write HTML. Style it with CSS.

Your pages are .html files. Components declare their props and state in HTML. Write their styles in CSS and add behavior with JavaScript or TypeScript.

Give every page a home.

A folder of pages becomes your routes. Share layouts, load data, and add API endpoints when your application needs them. MarkupKit handles development, builds, and delivery.

Build for the browser and the server.

Prerender pages for a static host, or render them on each request. HTML Next connects the page's components and browser behavior. Choose how to deploy for your application.

Built on the next generation of HTML.

MarkupKit uses HTML Next, the implementation of the Next Web Working Group's declarative components proposal. These proposed capabilities are available through its runtime today.

From Threadlabs, alongside Markupress.

Markupress builds documentation on MarkupKit. It powers this site, too. MarkupKit handles the application; Markupress handles Markdown, navigation, and documentation versions.
