How do React, Vue and Angular differ in bundle size and initial load time in 2025?

This compares gzipped bundle sizes and First Contentful Paint (FCP) times across the three frameworks.

Real-world metrics indicate: • Vue: Smallest bundle (~20–35 KB), fastest load (~150–300 ms FCP). • React: Moderate bundle (~30–50 KB), quick load (~200–400 ms FCP). • Angular: Largest bundle (~50–65 KB) and slower initial load (~400–800 ms FCP), though AOT and tree-shaking help improve performance ([turn0search0]turn0search6]turn0search2]).
