Marko is a declarative, HTML-based language and framework for building dynamic, reactive web user interfaces, where nearly any valid HTML is valid Marko. It features an optimizing compiler, streaming and resumable server-side rendering, and a tiny runtime, and is used in production at eBay.

Use cases

• build reactive web apps using HTML-like syntax
• server-side render pages with streaming and resumability
• create reusable UI components for isomorphic apps
• minimize client-side JavaScript shipped to the browser
• build a full-stack app with Marko Run and file-based routing
• progressively enhance static HTML with interactive islands

When to choose

• you want an HTML-first declarative UI language with minimal new concepts
• you need fast first paint via streaming SSR with little or no client JS
• you are building high-traffic production sites where performance matters
• you want compile-time optimizations and automatic asset lazy loading

When to avoid

• your team is invested in a mainstream ecosystem like React, Vue, or Svelte with large community support
• you need a vast ecosystem of third-party components and libraries
• you prefer JSX or a JavaScript-centric component authoring model
• you are building native mobile or desktop apps
