How do React, Vue, and Angular compare in bundle size, initial load, and memory usage?

This question examines benchmark data comparing initial bundle size, initial load times (e.g. First Contentful Paint), and runtime memory usage as of 2025.

According to 2025 benchmarks ([turn0search2]): • Vue wins performance for small footprint: bundle size ~20–40 KB, initial load times ~150–300 ms, and most efficient memory usage. • React follows closely with moderate bundle (~30–50 KB) and load times (~200–400 ms). It benefits from concurrent rendering and automatic batching. • Angular typically has the largest footprint (~50–100 KB) and slower initial load (~400–800 ms), but enterprise optimization mechanisms (AOT, OnPush) improve runtime speed ([turn0search2]).
