How do React, Vue, and Angular stack up in terms of bundle size and initial load time in 2025?

Compares gzipped bundle sizes and First Contentful Paint (FCP) metrics to evaluate initial load performance.

Real-world data indicates: • Vue: Smallest bundle (~34.7 KB), fastest load time (~1.2 s FCP). • React: Moderate bundle (~44 KB), fastest FCP (~0.8 s) with Server Components and Concurrent Mode optimizations. • Angular: Largest bundle (~62 KB) with slower FCP (~1.1 s) unless optimized with AOT/Ivy.
