Executive Summary
Choosing the right UI framework is a critical technical and business decision that impacts development velocity, application performance, team hiring, and long-term maintainability. This guide compares the leading frameworks across rendering capabilities, performance characteristics, developer experience, and ecosystem maturity to help you make informed decisions aligned with your project requirements and organizational constraints.
Framework Landscape Overview
The modern framework ecosystem divides into two categories: core UI libraries (React, Vue, Svelte, Angular, Solid, Qwik) and meta-frameworks that add routing, rendering, and deployment features (Next.js, Remix, Nuxt, SvelteKit, Astro, Qwik City). Core libraries focus on component architecture and reactivity, while meta-frameworks provide full-stack capabilities including SSR, SSG, and API routes.

| Vue 3 (standalone) | ✓ Native | Via meta-framework | Via meta-framework | Full hydration | Composition API, reactivity system |
| Nuxt 3 (Vue) | ✓ | ✓ Native | ✓ Native | Full hydration | Auto-imports, hybrid rendering |
| Svelte (standalone) | ✓ Native | Via meta-framework | Via meta-framework | Full hydration | Compile-time optimization, no virtual DOM |
| SvelteKit (Svelte) | ✓ | ✓ Native | ✓ Native | Full hydration | File-based routing, adapters for deployment |
| Angular | ✓ Native | ✓ Native | ✓ Native | Full hydration | Full framework, dependency injection, RxJS |
| Solid | ✓ Native | ✓ Native | ✓ Native | Full hydration | Fine-grained reactivity, no virtual DOM |
| Qwik / Qwik City | ✓ | ✓ Native | ✓ Native | Resumability (no hydration) | Zero JavaScript by default, lazy execution |
| Astro | ✓ | ✓ Native | ✓ Native | Partial hydration | Multi-framework, islands architecture |
