Web frameworks give you the scaffolding for building anything from a static blog to a full application with server rendering, routing, and state management already worked out. This category covers UI libraries like React and Svelte, meta-frameworks like Next.js, Nuxt, and Astro that add routing, data fetching, and build tooling on top, and full-stack frameworks such as core that handle backend concerns too. Some repos here are minimal and unopinionated, leaving architecture decisions to you; others ship with conventions for file-based routing, data loading, and deployment baked in.
Choosing between them depends on what you're building and how much structure you want. A content-heavy site with mostly static pages fits well with Astro's island architecture, where JavaScript ships only where needed. An app with frequent client-side interactivity and a large team already familiar with React works well with Next.js, which adds server rendering, API routes, and image optimization on top of React. Svelte and its Nuxt-adjacent counterparts compile away much of the runtime overhead, producing smaller bundles at the cost of a smaller ecosystem than React's. Nuxt plays a similar role for Vue that Next.js plays for React.
When comparing projects, look at:
Most of these projects are permissively licensed (MIT), so licensing is rarely the deciding factor. The bigger tradeoff is usually between flexibility and convention, and between bundle size and ecosystem maturity.
